Overview of the motor construction 

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 designed for water cooling (main cooler). The cooler has a 

different design for each of the different sizes (external diameter). 

●  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. 

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.
