Cooling and ventilation
The machines of this series are three-phase asynchronous machines with a closed primary
(internal) cooling circuit and an open secondary cooling circuit (surface cooling). The surface
cooling varies depending on the version.
3.3.3.1
Machines with a fan
Self-ventilation (standard): Cooling IC 411 in accordance with EN / IEC 60034-6
Located at the ND end of the stator housing is an air intake cowl that guides the external air
on its way to the motor. The external air is drawn in through openings in the air intake cowl
and flows axially across the outer cooling ribs of the motor frame. The fan wheel for the
external flow of cooling air is attached to the machine shaft.
The fan wheels are bidirectional.
Check the cooling effect below rated speed in the case of frequent switching or braking – or
if the speed is controlled continually below the rated speed.
The motors have a metal fan.

3.3.4
Bearings
In order to support the machine shaft and maintain its position in the non-moving part of the
machine, only 2 rolling-contact bearings are used. One roller bearing performs the function
of a location bearing that transfers axial and radial forces from the rotating machine shaft to
the non-moving part of the machine. The second roller bearing is implemented as floating
and support bearing in order to allow thermal expansion inside the machine and transfer
radial forces.
The nominal (calculated) useful life of the bearings according to ISO 281 is at least 20,000
hours with utilization of the permissible radial/axial forces. However, the achievable useful
life of the bearings can be significantly longer in the case of lower forces (e.g. operation with
self-aligning couplings).
Roller bearings with permanent lubrication are maintenance-free.

Risk of dropping and swinging when transported suspended
If you transport the motor suspended from cables or ropes, the cables or ropes can break,
e.g. as a result of damage. Further, if not adequately attached, the motor can swing. This
can result in death, serious injury, or material damage.
• Use additional, suitable lifting equipment for transport and during installation.
• Two cables alone must be able to carry the complete load.
• Prevent the lifting equipment from sliding by appropriately securing it.
WARNING
Toppling over or slipping of the motor
The motor can slide or topple over if it is not correctly lifted or transported. This can result in
death, serious injury, or material damage.
• Use all the lifting eyes on the machine.
• When using the lifting eyes on the machine, do not attach any additional loads or
weight. The lifting eyes are only designed for the weight of the machine itself.
• Any eyes that are screwed in must be tightly fastened.
• Eyebolts must be screwed in right up to their supporting surface.
• Comply with the permissible eyebolt loads.

NOTICE
Damage to the motor
Damage can occur if incorrectly stored.
Take all precautions to protect the motor under extreme climatic conditions, e.g. salt-laden
and/or dusty, moist/humid atmospheres.
Choose a dry storage location which is safe from flooding and free from vibration. Repair any
damage to the packaging before putting the equipment into storage if this is necessary to
ensure proper storage conditions. In order to ensure protection against ground moisture,
locate machines, equipment and crates on pallets, wooden beams or foundations. Prevent
equipment from sinking into the ground. Do not impede air circulation under the stored items.
Covers or tarpaulins used to protect the equipment against the weather must not come into
contact with the surfaces of the equipment. Use wooden spacer elements to ensure that air
can circulate freely around the equipment.
Storing indoors
The storage rooms must provide protection against extreme weather conditions. They must
be dry, free from dust, frost and vibration and well ventilated.
Preparing for use
4.5 Transport and storage
Smoke extraction motors
26 Operating Instructions, 03/2016, 5 610 80000 40 018
Bare metal surfaces
For transport, the bare surfaces (shaft ends, flange surfaces, centering edges) should be
coated with an anti-corrosion agent which will last for a limited amount of time (<6 months).
Apply suitable anti-corrosion measures for longer storage times.
Condensation drain hole
Open any condensation drain holes to drain the condensation depending on the
environmental conditions, every six months at the latest.
Storage temperature
Permissible temperature range: -20 °C to +50 °C
Maximum permissible air humidity: 60%
For machines that have a special design regarding the coolant temperature in the operating
state or the installation altitude, other conditions could apply regarding the storage
temperature. In this case, refer to the machine rating plate for data on the coolant
temperature and installation altitude.
Storage time
Turn the shaft once every year to avoid bearing brinelling. Prolonged storage periods reduce
the useful life of the bearing grease (aging).
Open bearings
● For open bearings, e.g. 1Z, check the status of the grease when stored for longer than 12
months.
● Replace the grease if it is identified that the grease has lost its lubricating properties or is
polluted. The consistency of the grease will change if condensation is allowed to enter.
Closed bearings
● For closed bearings, replace the DE and NDE bearings after a storage time of 48 months.
NOTICE
Storage
The motor can be damaged if you use it or store it unprotected outdoors.
• Protect the motor against intensive solar radiation, rain, snow, ice and dust. Use a
superstructure or additional cover, for example.
• If required, contact the Siemens Service Center, or technically coordinate outdoors use.

Operating Instructions, 03/2016, 5 610 80000 40 018 27
4.6
Electromagnetic compatibility
Note
If the torque levels are very unequal (e.g. when a reciprocating compressor is being driven),
a non
-sinusoidal machine current will be induced whose harmonics can have an
impermissible effect on the supply system and
cause impermissible interference emissions
as a result.
Note
Converter
•
If operated with a frequency converter, the emitted interference varies in strength,
depending on the design of the converter (type, interference suppression measures,
manufacturer).
•
Avoid that the specified limit values stipulated for the drive system (consisting of the
motor and converter) are exceeded.
•
You must observe the EMC information from the manufacturer of the converter.
•
The most effective method of shielding is to conductively connect a shielded machine
supply cable to the metal terminal box of the machine (with a metal screw connection)
over a large surface area.
•
On machines with integrated sensors (e.g. PTC thermistors), disturbance voltages
caused by the converter may occur on the sensor cable.
When used in accordance with their intended purpose and operated on an electrical supply
system with characteristics according to EN 50160, the enclosed machines comply with the
requirements of the EC Directive concerning electromagnetic compatibility.
Immunity to interference
The machines in principle fulfill the requirements of interference immunity in conformity with
EN / IEC 61000-6-2 . If machines with integrated sensors (e.g. PTC thermistors) are used,
the operating company must ensure sufficient interference immunity by selecting a suitable
sensor signal lead (possibly with shielding, connected in the same way as the machine
feeder cable) and a suitable evaluation unit.
When operating the machines from a converter at speeds higher than the rated speed, then
the mechanical speed limits must be carefully observed (safe operating speed
EN / IEC 60034-1).

Converter operation
4.7.1
Parameterizing the converter
● If the design of the motor requires connection to a particular converter type, the rating
plate will contain corresponding additional information.
● Correctly parameterize the converter. Parameterizing data can be taken from the
machine rating plate (not the supplementary rating plate with the operating data when
connected to a converter).
You can find parameter data here:
– In the operating instructions for the converter.
– In the SIZER engineering tool
– In the SINAMICS Configuration Manuals.
– For explosion-protected machines, also in the declaration of compliance with the order
2.1.
● Do not exceed the specified maximum speed limit nmax. You can either find this on the
rating plate nmax, on the supplementary plate for converter operation as the highest
speed, or in the type-specific catalog.
● Operate the machine only for a short period at the maximum speed. Operating the
machine for an extended period at the maximum speed may cause vibrations with an
increased frequency and consequently higher noise levels.
● Check that the machine is cooled sufficiently for commissioning purposes.
4.7.2
Reducing bearing currents during operation with converter (low voltage)
Taking the following actions will reduce the bearing currents:
● Ensure that the contacts are established over a large area. Solid copper cables are not
suitable for high frequency grounding because of the skin effect.
Equipotential bonding conductors:
Use equipotential bonding conductors:
● Between motor and driven machine
● Between motor and converter
● Between the terminal box and the RF grounding point at the motor enclosure.
Preparing for use
4.7 Converter operation
Smoke extraction motors
Operating Instructions, 03/2016, 5 610 80000 40 018 29
Selecting and connecting the cable
:
As far as possible, use symmetrically arranged, shielded connection cables. The cable
shielding, made up of as many strands as possible, must have good electrical conductivity.
Braided shields made of copper or aluminum are very suitable.
● The shield is connected at both ends, at the motor and converter.
● To ensure good discharging of high-frequency currents, provide contacting over a large
surface area:
– as contact established through 360° at the converter
– at the motor, for instance with EMC glands at the cable entries
● If the cable shield is connected as described, then it ensures the specified equipotential
bonding between the motor enclosure and converter. A separate RF equipotential
bonding conductor is then not necessary.
Concentric copper or aluminum shield
Steel armor
● If the cable shield is not connected due to special secondary conditions, or not
adequately connected, then the specified equipotential bonding is not provided. In this
particular case, use a separate RF equipotential bonding conductor:
– Between the motor enclosure and protective ground rail of the converter.
– Between motor enclosure and driven machine
– Use braided flat copper straps or high-frequency cables with finely-stranded
conductors for the separate RF equipotential bonding cable. Solid copper cables are
not suitable for high frequency grounding because of the skin effect.
– Ensure that the contacts are established over a large area.
Overall system design
To specifically reduce bearing currents, you must consider the system as a whole, which
comprises the motor, converter, and driven machine. The following measures support you
when reducing bearing currents and help to avoid damage:
● In the overall system, set up a properly meshed grounding system with low impedance.
● Use the common-mode filter (damping cores) at the converter output. The Siemens sales
representative is responsible for selection and dimensioning.
● Limit the rise in voltage by using output filters. Output filters dampen the harmonic content
in the output voltage.

Insulation resistance and polarization index
Measuring the insulation resistance and polarization index (PI) provides information on the
condition of the machine. It is therefore important to check the insulation resistance and the
polarization index at the following times:
● Before starting up a machine for the first time
● After an extended period in storage or downtime
● Within the scope of maintenance work
The following information is provided regarding the state of the winding insulation:
● Is the winding head insulation conductively contaminated?
● Has the winding insulation absorbed moisture?
As such, you can determine whether the machine needs commissioning or any necessary
measures such as cleaning and/or drying the winding:
● Can the machine be put into operation?
● Must the windings be cleaned or dried?

Testing the insulation resistance and polarization index
WARNING
Hazardous voltage at the terminals
During and immediately after measuring the insulation resistance or the polarization index
(PI) of the stator winding, hazardous voltages may be present at some of the terminals.
Contact with these can result in death, serious injury or material damage.
• If any power cables are connected, check to make sure line supply voltage cannot be
delivered.
• Discharge the winding after measurement until the risk is eliminated, e.g. using the
following measures:
– Connect the terminals with the ground potential until the recharge voltage drops to a
non-hazardous level
–
Attach the connection cable.
Measure the insulation resistance
1. Before you begin measuring the insulation resistance, please read the operating manual
for the insulation resistance meter you are going to use.
2. Make sure that no power cables are connected.
3. Measure the winding temperature and the insulation resistance of the winding in relation
to the machine enclosure. The winding temperature should not exceed 40° C during the
measurement. Convert the measured insulation resistances in accordance with the
formula to the reference temperature of 40° C. This thereby ensures that the minimum
values specified can be compared.
4. Read out the insulation resistance one minute after applying the measuring voltage.
Limit values for the stator winding insulation resistance
The following table specifies the measuring voltage and limit values for the insulation
resistance. These values correspond to IEEE 43-2000 recommendations.

Halving/doubling of the insulation resistance with 10 K
T
Measuring/winding temperature in °C
In this case, doubling or halving the insulation resistance at a temperature change of 10 K is
used as the basis.
● The insulation resistance halves every time the temperature rises by 10 K.
● The resistance doubles every time the temperature falls by 10 K.
For a winding temperature of approx. 25° C, the minimum insulation resistances are 20 MΩ
(U ≤ 1000 V) or 300 MΩ (U > 1000 V). The values apply for the complete winding to ground.
Twice the minimum values apply to the measurement of individual assemblies.
● Dry, new windings have an insulation resistance of between 100 and 2000 MΩ, or
possibly even higher values. An insulation resistance value close to the minimum value
could be due to moisture and/or dirt accumulation. The size of the winding, the rated
voltage and other characteristics affect the insulation resistance and may need to be
taken into account when determining measures.
● Over its operating lifetime, the motor winding insulation resistance can drop due to
ambient and operational influences. Calculate the critical insulation resistance value
depending on the rated voltage by multiplying the rated voltage (kV) by the specific
critical resistance value. Convert the value for the current winding temperature at the time
of measurement, see above table.
Measuring the polarization index
1. To determine the polarization index, measure the insulation resistances after one minute
and ten minutes.
2. Express the measured values as a ratio:
PI = Rinsul 10 min / Rinsul 1 min
Many measuring devices display these values automatically following the measurement.
For insulation resistances > 5000 MΩ, the measurement of the PI is no longer meaningful
and consequently not included in the assessment.

Machines with type of construction IM B15, IM B9, IM V8 and IM V9
Types of construction without bearings on the drive side
These machines do not have their own bearing system for the machine shaft at the drive end
(DE). The machine shaft is accepted by the (hollow) shaft or coupling of the system or driven
machine.
● Using the centering edge, the machine is aligned with respect to enclosures, flanges or
driven machines.
● Note that the temperature of the motor and motor shaft increases during operation. The
thermal expansion of the machine shaft must be compensated by the customer by
applying suitable measures.
Use the spring washers provided to locate the NDE bearing without any play.
NOTICE
Damage to the motor
Material damage can occur if the following notes are not carefully observed:
• The IM B3 bearing shield with built-in distance ring mounted at the DE is only used as
transport lock. A warning label is attached to this bearing shield.
• The spacer ring is not a roller bearing.
• Remove the bearing shield and the spacer ring.
• Remove the transport lock before commissioning.

Foot mounting
Note
Only authorized retrofit partners must be employed to relocate the bolted on mounting feet at
the machine enclosure.
After attaching the mounting feet, you must note the following in order to avoid stressing and
deforming the machine.
● Ensure that the foot mounting surfaces are aligned in one plane and are parallel to the
machine shaft.
● Post-machine the foot mounting surfaces or use thin shims, for example.
● Professionally touch up damaged painted surfaces.
● Observe the information provided in Chapter Aligning and mounting
5.4.5
Balancing
The rotor is dynamically balanced. The balancing quality corresponds to vibration severity
grade "A" for the complete machine as standard. The optional vibration severity grade "B" is
indicated on the rating plate.
The declaration regarding the type of featherkey for balancing is generally marked on the
rating plate and optionally on the face of the shaft end.
Designation:
● As a standard measure, balancing is carried out dynamically with a half featherkey (code
"H") in accordance with ISO 8821.
● "F" means balancing with a whole featherkey (optional version).
● "N" means balancing without a featherkey (optional version).
CAUTION
Incorrect installation or removal
To avoid injury and material damage, carefully observe general touch protection measures
for output transmission elements:
• The general touch protection measures for drive output elements must be observed.
• Drive output elements may only be pushed on or pulled off with the correct equipment.
• The feat
her keys are only locked against falling out during shipping. If you commission a
machine without a drive output element, the feather keys must be secured to prevent
them from being thrown out.
Assembly
5.4 Installation
Smoke extraction motors
42 Operating Instructions, 03/2016, 5 610 80000 40 018
The featherkey data on the shaft and transmission element must indicate the correct type of
balancing in each case and must be correctly mounted.
The balancing quality corresponds to vibration severity grade "A" for the complete machine;
vibration severity grade "B" is possible as an option, i.e. in order to ensure the desired
balancing quality, it must be ensured that the featherkey data on the hub and machine shaft
complement each other in the case of a shorter or longer output transmission element.
WARNING
Risk that the function will not be able to be maintained in the case of a fault/fire
Temperature-related fan imbalance and temperature-related changes to mounting
resonance points in the equipment result in vibration levels that automatically increase. This
can result in material damage, injury and death.
Before balancing, anneal the output transmission elements (fans) to relieve any internal
stress. Avoid any mounting resonance points in the equipment close to operating speeds.
Align the offset at the coupling between electrical machines and the driven machines so that
the maximum permissible vibration values according to ISO 10816 are not exceeded.

Avoid inadmissible vibration caused by imbalance, for example (drive output element),
external vibration or any resonance over the complete speed range.
It may be necessary to completely balance the machine with the drive output element or
the system resonance frequency must be shifted.
●
Foot mounting/flange mounting
– Use the specified thread sizes laid down in EN 50347 when flanging the machine to a
foundation or a machine flange.
– Mount the machine at four foot or flanged holes that are at right angles to one another.
The customer is responsible for selecting the strength (property class) of the mounting
elements.
For mounting elements up to and including frame size 160, property class 5.6 or
higher is recommended, from frame size 180, property class 8.8 or higher.
– Select the correct screw length for IM B14 flanges.
●
IM B30 pad mounting (duct fans or fans installed in pipes)
To install the motor in the equipment, use all DE and NDE mounting brackets or all 8
bores in the enclosure.
Use suitable locking measures to prevent the connections from being released in normal
operation and operation under fault/fire conditions.

Hazardous voltages
Death, injury or material damage can occur. Note the following safety information before
connecting-up the machine:
• Only qualified and trained personnel should carry out work on the machine while it is
stationary.
• Disconnect the machine from the power supply and take measures to prevent it being
reconnected. This also applies to auxiliary circuits.
• Check that the machine really is in a no-voltage condition.
• Establish a safe protective conductor connection before starting any work.
• If the incoming power supply system displays any deviations from the rated values in
terms of voltage, frequency, curve form or symmetry, such deviations will increase the
temperature and influence electromagnetic compatibility.
• Operating the machine on a line supply system with a non-
grounded neutral point is only
permitted over short time intervals that occur rarely, e.g. the time leading to a fault being
eliminated (ground fault of a cable, EN 60034-1).
Observe the information in EN / IEC 60034-1 (VDE 0530-1) regarding operation at the limits
of the A zones (±5 % voltage difference and ±2 % frequency difference) and the B zones,
especially in respect of temperature increase and deviation of the operating data from the
rated data on the rating plate. Never exceed the specified limits!
Connect up so that a permanently safe electrical connection is guaranteed (no protruding
wire ends); use the assigned cable-end fittings (e.g. cable lugs, end sleeves).
Connect up the line supply voltage and arranged the disconnecting link in accordance with
the circuit diagram provided in the terminal box.
Select connecting cables according to DIN VDE 0100 taking into account the rated current
and the system-dependent conditions (e.g. ambient temperature, routing type etc. according
to DIN VDE 0298 or EN / IEC 60204-1).

6.2.3
Connection with/without cable lugs
In the case of terminals with terminal clamps, distribute the conductors in such a way that the
clamping heights on both sides of the fillet are about the same. This method of connection
requires that you must bend a single conductor in a U shape or use a cable lug. The same
applies to the inner and outer terminals of the ground conductor.
When connecting up using cable lugs, select their size corresponding to the required cable
cross-section and the stud size. An inclined arrangement is only permitted provided the
required air clearances and creepage distances are carefully maintained.
Remove insulation from the ends of the conductors so that the remaining insulation almost
reaches the cable lug.
Note
The di
rect contact between the cable lug surfaces and the contact nuts or contact screws
ensure that the connection can conduct current.
6.2.4
Connecting protruding cables
In the case of connection cables brought out of the machine, no terminal board is installed

● Start the machine without a load. To do this, close the circuit breaker and do not switch
the machine off prematurely. Switching the machine off again while it is starting up and
still running at slow speed should be kept to a bare minimum, for example for checking
the direction of rotation or for checking in general. Allow the machine to run to a standstill
before switching it back on again.
● Check mechanical operation for noise or vibration at the bearings or end shields.
● If the machine is not running smoothly or is emitting abnormal noises, switch it off, and
determine the cause of the fault as it runs down.
● If mechanical operation improves immediately after the machine is switched off, then the
cause is magnetic or electrical, e.g. voltage imbalance, magnetic imbalance. If
mechanical operation does not improve immediately after switching the machine off, then
the cause is mechanical, e.g. an imbalance in the electrical machines or in the driven
machine, inadequate alignment of the machine set, operation of the machine with the
system resonating (system = machine + base frame + foundations etc.).
● If the machine runs perfectly in terms of its mechanical operation, switch on any cooling
devices present and continue to monitor the machine for a while as it idles.
● If it runs perfectly, connect a load. Check that it runs smoothly.
Read off and document the values for voltage, current, and power.
Where possible, read off corresponding values for the driven machine and document
them as well.
● Monitor the bearing temperature, winding temperature, etc. until the system reaches a
steady state.
Document these, provided this is possible with existing measuring instruments.
Commissioning measures for smoke extraction motors according to EN 12101-3
● The procedures laid down in EN 12101-3 must be complied with when testing the motors,
installed in the fan unit.
● Plot the input power curve and temperature-time characteristic in the fire testing room.
Record the vibration response at the end shields radially in at least one direction
according to ISO 10816 throughout the entire test period.
Do not exceed the values specified in the Balancing chapter.
● When installing in the fire testing room, avoid directly exposing the unit, machine and
cable to flames.
Avoid abrasion points of connection cables and cables on metallic components.

Re-greasing
For machines with regreasing system, relubrication intervals, grease quantity and grease
grade are provided on the lubricant plate. Additional data can be taken from the main
machine rating plate.
Grade of grease for standard motors (IP55) UNIREX N3 - ESSO.
Note
It is not permissible to mix different types of grease.
Prolonged storage periods reduce the useful lifetime of the bearing grease. Check the
condition of the grease if the equipment has been in storage for more than 12 months. If the
grease is found to have lost oil content or to be contaminated, the machine must be
immediately relubricated before commissioning. For information on permanently-greased
bearings, please refer to the section titled Storage (Page 76).
Procedure
To relubricate the roller bearings, proceed as follows:
1. Clean the grease nipples at the drive end and non-drive end.
2. Press-in the specified grease and amount of grease according to the data stamped on the
lubrication plate.
– Please observe the information on the rating and lubricant plates.
– Regreasing should be carried out when the motor is running (max. 3600 rpm).
The bearing temperature can rise significantly at first, and then drops to the normal value
again when the excess grease is displaced out of the bearing.
NOTICE
This invalidates the warranty and operational safety
Mixing different types of grease can lead to material damage on the machine.
If you use or mix types of grease other than UNIREX N3, this invalidates the warranty and
standard conformity with the EN 12101-3 test standard.
Only use UNIREX N3 for re-lubrication purposes.
9.4.3
Cleaning
Cleaning the grease ducts and spent grease chambers
The spent grease collects outside each bearing in the spent grease chamber of the outer

The machines consist mainly of steel and various proportions of copper and aluminum.
Metals are generally considered to be unlimitedly recyclable.
Sort the components for recycling according to whether they are:
● Iron and steel
● Aluminum
● Non-ferrous metal, e.g. windings
The winding insulation is incinerated during copper recycling.
● Insulating materials
● Cables and wires
● Electronic waste
Process materials and chemicals
Sort the process materials and chemicals for recycling according to whether they are for
example:
● Oil
● Grease
● Cleaning substances and solvents
● Paint residues
● Anti-corrosion agent
● Coolant additives such as inhibitors, antifreeze or biocides
Dispose of the separated components according to local regulations or via a specialist
disposal company. The same applies for cloths and cleaning substances which have been
used while working on the machine.
Packaging material
● If necessary, contact a suitable specialist disposal company.
● Wooden packaging for sea transport consists of impregnated wood. Observe the local
regulations.
