2.4 Working on machines with permanent magnets
A5E02446774A AB
14 Siemens AG Operating Instructions V2.00 1PH8
2.4 Working on machines with permanent magnets
On machines with permanent magnets, the magnetic field is guided in an assembled state in
the magnetic circuit of the motor. This means that no magnetic fields, which may be to your
health, are detectable outside the machine.
WARNING
Strong magnetic field when the machine is open
A strong magnetic field is always present inside the machine. If the housing is open, e.g.
when maintenance openings are open or when working inside the machine, magnetic
objects can be suddenly attracted by this magnetic field. This can result in death, severe
injury or material damage.
Working in the vicinity of the rotor is only permitted in exceptional circumstances.
Unambiguous access rules must be established in accordance with the magnetic fields
prevailing in the workplace. Clearly mark the boundaries of the areas where standing is
permitted.
People who need to use electronic or magnetic medical aids such as pacemakers, hearing
aids, implants or similar devices, are at particularly high risk. Such persons must undergo
an industrial medicine assessment.
Observe the following measures.
Personal protective measures
● Ensure that you never wear or carry any of the following objects and that they are kept a
safe distance from the machine:
– All kinds of magnetic metal parts such as, keys, glasses, tools, knives, scissors, tape
measures, etc.
– Magnetic jewelry such as rings, chains, needles, watches, etc.
– Electronic devices and data carriers such as service cards, check cards, credit cards,
calculators, cell phones, etc.
– Wallets or other iron-containing objects
– Electrically conductive foreign bodies
● Do not use any magnetic tools or lifting devices.
● Wear only occupational safety items without magnetic metal parts, e.g. occupational
safety shoes with non-magnetic protective caps and soles.
● Keep your shoes and clothing free from chips and waste containing iron.
● Exercise caution when installing accessories. Ensure that no parts fall into the inside of
the machine.
● Do not perform any cutting at the machine, e.g. manufacturing threaded holes. Any
exceptions require written approval from the manufacturer.

Fixing by means of motor feet
● The contact surfaces of the motor feet must lie on one plane. If the motor needs to be
aligned, position metal shims underneath the feet in order to prevent machine
deformation.
The number of shims should be kept as low as possible i.e. stack as few as possible.
● Select foot screws as per ISO 898-1 in compliance with the load conditions and machine
type:
Type Foot screw size
1PH818. M12
1PH822. M16
Fixing by means of flange only
The flange is only used to transfer the torque. Due to the empty weight or as a result of
vibrations that arise if the flange is too soft, the motor can be damaged if it is only fastened
via the flange.
1. Fasten the flange motors via a stable motor suspension and support them via the end
shield feet (foot flange type of construction).
2. During commissioning, ensure that the permitted vibration values are maintained in
accordance with ISO 10816-3.
If the machine is only to be secured via the flange, with a rigid base the maximum speed
is lowered as follows:
– Max. 3000 1/min for 1PH818.
– Max. 2500 1/min for 1PH822.
5.6 Pushing on the power output elements
Balance quality
The rotors are balanced dynamically. For shaft extensions with featherkeys, the balancing
type is specified using the following coding on the face of the drive end of the shaft:
● "H" means balancing with a half feather key
● "F" means balancing with a whole feather key.

Pushing on the power output elements
● Make sure that the balancing method of the output element is correct!
● If the power output element is shorter than the feather key with balancing type "H", then
you must machine off the section of feather key protruding from the shaft contour and
output element in order to maintain the balance quality.
● Power output elements may only be pushed on or pulled off with the correct equipment.
WARNING
The feather key can fall out
The featherkeys are only secured during transport to prevent them from falling out. If a
machine with two shaft extensions does not have an output element on one shaft
extension, the feather key can fall out during operation.
Death or serious injury can result.
On shaft extensions without output element, make sure that the feather key cannot fall
out and shorten it by approximately half for balance type "H".

6.2.11 Connection to a converter
Selecting and connecting the cable
● Use Motion Connect cables or symmetrically constructed, shielded cables to connect the
motor to a converter. The cable shielding, made up of as many strands as possible, must
have good electrical conductivity. Braided shields made of copper or aluminum are well
suited.
● The shield must be connected at both ends to the motor and the converter; unshielded
cable ends must be kept as short as possible.
● To ensure effective discharge of high-frequency currents, make the shield contact over
the largest possible area, i.e. as a 360° contact on the converter and motor, e.g. using
EMC glands at the cable entry points.
Measures to reduce bearing currents
To specifically reduce and prevent damage caused by bearing currents, you must consider
the system as a whole, which comprises the motor, converter, and driven machine. The
following precautions help to prevent bearing currents:
● Setting up a properly meshed grounding system in the system as a whole, with low
impedance for high-frequency currents
● No potential difference between the motor, converter, and working machine.
– Use symmetrical, shielded connecting cables.
– Connect the cable shield at both ends over the greatest possible surface area (360°
contact).
– Use equipotential bonding conductors between the motor and driven machine, motor
and converter and inside the motor
● Use iron cores mounted above the motor connecting cable at the converter output. These
help to reduce common-mode components. The Siemens sales representative is
responsible for selection and dimensioning.
● Limit the voltage rate of rise by using an output filter to dampen harmonic components in
the output voltage

Observe the general safety instructions (Page 11) for all work on the machine.
WARNING
Driving the motor via the system
During a short circuit of a cable or converter, a short-circuit current is driven by the induced
voltage which is present at the motor terminals due to the rotation of the permanent magnet
rotors. The motor can rotate unexpectedly at any time, which can result in death, serious
injury, or material damage.
If it is possible for the motor to be passively driven during system operation, ensure that
short-circuit-resistant cables are used.
Optionally, you can use circuit breakers near the motor for protecting the sections of
cable during a short circuit.
WARNING
Dangerous voltage at the motor terminals when the rotor is rotating
There is always a magnetic flux in the motor due to the permanent magnets in the rotor.
With each rotation of the rotor, a voltage occurs at the motor terminals. As a result of this,
there is also a voltage at the converter output terminals via the connecting cable. Contact
with them can cause death, serious injury or material damage.
When working on the drive system, you must prevent any rotational movement of the
motor shaft.
WARNING
Dangerous voltage via the converter
As long as the feeding converter is switched on, or the DC link of the converter is not
discharged, there can be a voltage at the motor terminals even when the rotor is not
moving. Contact with them can cause death, serious injury or material damage. The voltage
is up to 1000 V, depending on the converter type.
Maintain the five safety rules (Page 11)at all times when operating the machine.

A5E02446774A AB
Siemens AG Operating Instructions V2.00 1PH8 45
7.2 Trial run
● If you want to start the motor for a trial run, connect it to the cooling water supply.
WARNING
Risk of burning from hot steam
If the cooling water supply fails, the motor will overheat. If cooling water runs into the hot
motor, hot steam suddenly forms, which escapes under high pressure. The cooling
water system can burst. This can result in death, serious injury or material damage.
Do not connect the cooling water supply until the motor has cooled down.
7.3 Checking insulation resistance
Safety note
WARNING
Only expert personnel should be entrusted with work on power installations.
Checking the insulation resistance
After long storage or shutdown periods, the insulation resistance of the windings must be
measured to ground with direct voltage.
CAUTION
Before you begin measuring the insulation resistance, please read the manual for the
insulation resistance meter you are going to use.
WARNING
Hazardous voltage
During the measurement, and immediately afterwards, hazardous voltage levels are
applied on some of the terminals and they should not be touched. Touching live
components can be result in death or serious injury.
Never touch the terminals when measuring or immediately after the measurement.
Check the supply feeder cables connected in order to ensure that the line supply voltage
cannot be connected.
● Always measure the insulation resistance of the winding to the motor enclosure when the
winding temperature is between 20 and 30°C.
● When measuring, wait until the final resistance value is reached; this takes approximately
one minute.

7.3 Checking insulation resistance
A5E02446774A AB
46 Siemens AG Operating Instructions V2.00 1PH8
Limit values
The table below specifies the measuring circuit voltage as well as the limit values for the
minimum insulation resistance and the critical insulation resistance with a rated motor
voltage of UN < 2 kV:
Table 7-1 Stator winding insulation resistance at 25 °C
Rated voltage UN < 2 kV
Measuring circuit voltage 500 V (at least 100 V)
Minimum insulation resistance with new, cleaned or repaired
windings
10 MΩ
Critical specific insulation resistance after a long operating
time
5 MΩ/kV
Note the following:
● Dry, new windings have insulation resistance of between 100 and 2000 MΩ, or possibly
values that are even higher.
If the insulation resistance is close to the minimum value, then the cause could be
humidity and/or fouling.
● Over its operating lifetime, the motor winding insulation resistance can drop due to
ambient and operational influences. The critical insulation resistance for a temperature of
25°C on the winding can be calculated by multiplying the rated voltage (kV) by the
specific critical resistance value (5 MΩ/kV);
Example: Critical resistance for a rated voltage (UN) of 500 V:
500 V x 5 MΩ/kV = 2.5 MΩ
NOTICE
Cleaning and/or drying the windings when reaching critical insulation resistance
If the critical insulation resistance is less than or equal to this value, the windings must
be dried or, if the fan is removed, cleaned thoroughly and dried.
Note that the insulation resistance of dried, clean windings is lower than that of warm
windings. The insulation resistance can only be evaluated accurately when measured
on a winding that has been cooled down to room temperature (approx. 20 to 30°C).
NOTICE
Measured value close to critical value
If the measured value is close to the critical value, the insulation resistance should be
subsequently checked at appropriately frequent intervals.
Values apply for measurement at a winding temperature of 25 °C.

11.1 Introduction
Protecting the environment and preserving its resources are corporate goals of the highest
priority for us. Our worldwide environmental management system to ISO 14001 ensures
compliance with legislation and sets high standards in this regard. Environmentally friendly
design, technical safety and health protection are always firm goals even at the product
development stage.
Recommendations for the environmentally friendly disposal of the machine and its
components are given in the following section. Be sure to comply with local disposal
regulations.
11.2 Preparing for disassembly
Disassembly of the machine must be carried out and/or supervised by qualied personnel
with appropriate expert knowledge.
1. Contact a certified waste disposal organization in your vicinity. Clarify what is expected in
terms of the quality of dismantling the machine and provision of the components.
2. Follow the five safety rules (Page 11).
3. Disconnect all electrical connections.
4. Remove all liquids such as oil, water, …
5. Remove all cables.
6. Deatch the machine fixings.
7. Transport the machine to a suitable location for disassembly.
Refer also to the information in the section headed "Maintenance" (Page 55).
11.3 Working on machines with permanent magnets
On machines with permanent magnets, the magnetic field is guided in an assembled state in
the magnetic circuit of the motor. This means that no magnetic fields, which may be to your
health, are detectable outside the machine.
Disposal
11.4 Disposing of permanent magnets
A5E02446774A AB
78 Siemens AG Operating Instructions V2.00 1PH8
WARNING
Strong magnetic field when the machine is open
A strong magnetic field is always present inside the machine. If the housing is open, e.g.
when maintenance openings are open or when working inside the machine, magnetic
objects can be suddenly attracted by this magnetic field. This can result in death, severe
injury or material damage.
Working in the vicinity of the rotor is only permitted in exceptional circumstances.
Unambiguous access rules must be established in accordance with the magnetic fields
prevailing in the workplace. Clearly mark the boundaries of the areas where standing is
permitted.
People who need to use electronic or magnetic medical aids such as pacemakers, hearing
aids, implants or similar devices, are at particularly high risk. Such persons must undergo
an industrial medicine assessment.
Observe the following measures.
Personal protective measures
● Ensure that you never wear or carry any of the following objects and that they are kept a
safe distance from the machine:
– All kinds of magnetic metal parts such as, keys, glasses, tools, knives, scissors, tape
measures, etc.
– Magnetic jewelry such as rings, chains, needles, watches, etc.
– Electronic devices and data carriers such as service cards, check cards, credit cards,
calculators, cell phones, etc.
– Wallets or other iron-containing objects
– Electrically conductive foreign bodies
● Do not use any magnetic tools or lifting devices.
● Wear only occupational safety items without magnetic metal parts, e.g. occupational
safety shoes with non-magnetic protective caps and soles.
● Keep your shoes and clothing free from chips and waste containing iron.
● Exercise caution when installing accessories. Ensure that no parts fall into the inside of
the machine.
● Do not perform any cutting at the machine, e.g. manufacturing threaded holes. Any
exceptions require written approval from the manufacturer.
11.4 Disposing of permanent magnets
If the entire motor is melted down, no special action is required for the permanent magnets.
Remove all cables before the melting process.
Disposal
11.5 Disposal of components
A5E02446774A AB
Siemens AG Operating Instructions V2.00 1PH8 79
Description
If the motor is disassembled and dismantled, the permanent magnets must be
demagnetized. For this purpose, the motor should be heated to 350 °C. This is necessary to
ensure that no hazards result from the rotors during and after disposal. The disposal must be
carried out by an authorized waste disposal company.
NOTICE
Removing the permanent magnet rotor
Only authorized workshops and waste disposal companies are permitted to remove the
permanent magnet rotor.
Demagnetizing the rotors
Waste disposal companies that are authorized to demagnetize rotors use a specially
designed disposal furnace. The insides of the disposal furnace consist of non-magnetic
material. The rotors are put in the furnace in a solid, heat-resistant container made of non-
magnetic material and left in the furnace during the entire demagnetization procedure.
Demagnetization is achieved by heating the rotor in the furnace until the permanent magnets
have reached a temperature of 350 °C.
NOTICE
Preventing emissions
Escaping exhaust must be collected and rendered harmless without damaging the
environment.
Note
Authorized waste disposal companies
Information regarding authorized waste disposal companies and workshops can be obtained
from the Siemens Service Center.
11.5 Disposal of components
Components
The machines consist for the most part 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.
Disposal
11.5 Disposal of components
A5E02446774A AB
80 Siemens AG Operating Instructions V2.00 1PH8
● Insulating materials
● Cables for printers with
● 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
Dispose of the separated components according to local regulations or via a specialist
disposal company. The same goes 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.
● The foil used for water-proof packaging is an aluminum composite foil. It can be recycled
thermically. Dirty foil must be disposed of via waste incineration.
