Motor components

4.1.1

Overview of the motor construction

The built-in torque motor contains the following components:
● Stator:
this comprises an iron core and a 3-phase winding.
The winding is encapsulated to ensure that the heat loss can be dissipated more
effectively. The motor is designed for water cooling (main cooler). The system design
depends on the frame size (external diameter) of the motor, see the "Cooling type
version" table at the end of this chapter.
● Rotor:
this is the reaction part of the motor. It comprises a cylindrical hollow steel shaft with
permanent magnets around its circumference.
● Cooling connection adapter (optional):
this can be ordered for motors with integrated cooling whereby the main and precision
cooler are operated in parallel on one heat-exchanger unit.
4.1.1.1

Motors with a cooling jacket

The cooling jacket surface of the motor contains circular grooves which, in conjunction with a
surrounding construction provided by the machine manufacturer, create a closed liquid
cooling circuit.
The coolant inlet/return flow circuit must be provided by the machine manufacturer in the
surrounding construction.
