Scope of delivery of the built-in torque motor with a cooling jacket 

●  The rotor is secured in the stator by means of transportation locks and a spacer film 
●  Stator with a cooling jacket; one cable for the power connection and one cable for the 

signal connection with connector or open core ends 

●  Transportation locks with spacers and screws 
●  O-rings (x 2) 2) 
●  Motor rating plate (attached); additional motor rating plate (not attached) 
●  Safety information 

Motors with integrated cooling 

These motors are equipped with a ready-to-connect, integrated dual-circuit cooling system, 

which provides considerable thermal insulation vis-à-vis the mechanical axes construction. 
The dual-circuit cooling system comprises a main and precision cooler  

(thermo-sandwich® principle). 
An internal cooling circuit (main cooler) dissipates most of the winding losses P

v

 of the stator. 

A thermal insulation layer between the stator and the mounting flanges of the stator prevents 

heat from flowing from the motor winding to the machine construction. 
Any heat that does flow through the insulation layer is captured, for the most part, by a 

second heat sink (precision cooler) on the flange surfaces and dissipated. This ensures that 

the temperature on the mounting surfaces of the stator remains suitably low under all 

permissible operating conditions.
