1 Basicrequirements
1PM4 hollow shaft motors conform with:
-98/37/EC MachineDirective
-73/23/EEC Low Voltage Directive and
-89/336/EEC ElectromagneticCompatibilityDirective.
Ensure that your end product conforms to all currently valid
legal requirements. Follow the compulsory national, local
and installation-specific regulations.
Starting up the motors is not permitted until the end product
conforms to this stipulations of the named guidelines.

motors.
The safety instructions must be observed during the
transport, storage, assembly, disassembly and operation
of the hollow shaft motors!
Failure to observe the instructions can lead to serious personal
injuries or property damage.
All activities (transport, storage, assembly, disassembly
of the hollow-shaft motors) must be performed by
qualified, skilled workers who are aware of the specific
dangers and who observe the stipulations of the present
operating instructions.
Maintenance (replacement of the gear encoder or bearing) may
only be performed by the manufacturer or authorized SIEMENS
service centers.
Mechanical hazards
Appropriate tools etc. are used for transport and assembly work
Lifting devices, ground conveyors and lifting tackle must
correspond to the valid regulations, e.g.:
EUDirectiveforMachines98/37EEC,appendix1
Regulations of the statutory industrial accident insurance institution
BGVD6, BGV D8,BGV D27, VBG9a ecc.
There is an injury hazard in the vicinity of the rotating motor.
The manufacturer of the end product is responsible for
protection against accidental contact with the rotating
motor.
Do not wear any additional clothing, jewelry or allow long
hair to hang freely.
Electricalhazards
The electrical connection to the hollow shaft motors is made as
described in the operating instructions.
All electrical work only must be performed by qualified
electricians and always with the equipment electrically
dead.
Requirements of qualified electricians according to
EN50110-1:1996(DINVDE0105-100):
- Knowledge of electrical engineering
- Experience of electrotechnical work
- Knowledge of the plant / machine
- Knowledge of the hazards and safety measures
- Ability to decide upon a safe working sequence.
Hollow-shaft motors are only driven with configured converters.
Any other connection can lead to their destruction.
Never connect the motors directly to an external three-
phase mains! The correct phase sequence is vital!
The temperature sensor and encoder system including electronics
contain electrostatically endangered components (EEC).
Do not touch the connections with your hands or with tools
which could be electrostatically charged!
Thermal hazards
The surface temperature of the motors may exceed 80oC (176oF).
Do not touch hot surfaces!
Temperature-sensitive components (electric lines, electronic
components) must not touch hot surfaces.
IntendedUsage
The motors correspond to the harmonized standards of the
EN60034(VDE0530)series.
They are intended for industrial or commercial plants.
Special case: More stringent requirements must be taken into
consideration during the configuration and assembly for use in non-
commercialplants.
Usage for the intended purpose includes observing all the
specifications in the operating instructions.
Ambienttemperatures:-15oCto+40oC(5oFto104oF)
The motors must be protected against frost if water is used as a
coolant.Site altitude: up to1000ma.s.l.
The conditions at the location of use must correspond to all the
informationon the rating plate.
It is forbidden to use them in areas at risk of explosion.
The operating instructions are part of the scope of delivery and shall
be kept in an accessible place.
The technical details of special versions and design variants of the
motors can vary.
Please contact the manufacturer or a SIEMENS service center if you
have any questions regarding the use or operational characteristics
of the motors.
2 Productinformation
2.1 Application range
The hollow shaft of the motor serves for the supply of cooling
lubricant or the insertion of collets. The motors are used if
-the environmental conditions are unsuitable for air cooling,
-theenvironmentmustnotbethermallypollutedor
-the motor has to have a high power density in a restricted
mounting space.
Application cases: Milling machines with full encapsulation, turning
lathes with driven tools or counterspindles.

2.3 Mode of operation and design
Motors of the 1PM4 series are water-cooled, four-pole
asynchronous motors. The squirrel-cage rotor (rotor) has a hollow
shaft.
- Core-and-winding assembly:
Temperature sensor for temperature measurement and
regulation, and to protect against overheating, fitted in the stator
winding (a second sensor as a reserve).
- Encoder system
Incremental encoder sin/cos (I-256) for measuring the motor
speed and the relative change in the rotor position (installed at the
ND-end).
