Motor components
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 a naturally cooled motor with air as cooling medium.
The stator has cooling ribs to increase the cooling surface for natural cooling.
● Rotor:
This is the reaction part of the motor. It comprises a cylindrical hollow steel shaft with
permanent magnets around its circumference.
