Basic requirements
1PM6 hollow shaft motors conform with:
- 98/37/EC
Machine Directive
- 73/23/EEC Low Voltage Directive and
- 89/336/EEC Electromagnetic Compatibility Directive.
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.
Observe the SIEMENS Project Planning Instructions for 1PM6 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.:
EU Directive for Machines 98/37 EC, appendix 1
Regulations of the statutory industrial accident insurance institution
BGV D6, BGV D8, BGV D27, VBG 9a 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.
Electrical hazards
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
EN 50110-1:1996 (DIN VDE 0105-100):
- 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 80
Do not touch hot surfaces!
Temperature-sensitive components (electric lines, electronic
components) must not touch hot surfaces.
Intended Usage
The motors correspond to the harmonized standards of the
EN 60034 (VDE 0530) 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-
commercial plants.
Usage for the intended purpose includes observing all the
specifications in the operating instructions.

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.

Product information
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 when the
environmental conditions enable the use of air cooling.
Application cases: Milling machines with full encapsulation, turning
lathes with driven tools or counterspindles.

Mode of operation and design
Motors of the 1PM6 series are water-cooled, four-pole
asynchronous motors. The squirrel-cage rotor (rotor) has a
hollow shaft.
Main subassemblies
- 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).
- Separate fan set 2CW83..
according to figs. 2.1 and 2.2 (three-phase, external-rotor motor),
arranged axially or radially (top or on the side).

Transport, Storage
WARNING
Danger during lifting and transporting
procedures.
Improper handling, unsuitable or defective
devices, tools etc. can cause injuries and/or
property damage.
Lifting devices, floor conveyors and lifting tackle
must conform to the currently valid regulations.
All the lifting eye-bolts provided (Fig. 2) should be used during
transport. Do not attach any additional loads.
