Typical fields of application of these motors are direct drives, e.g., in rotary
tables, swivel axes of machining centers, printing units as well as grinding
machines. But they also provide new solutions for innovative machine con‐
struction where robots, plastics machines, woodworking machines, lathes
and special machines are concerned. These motors have the following es‐
sential advantages:
● Maximum torques of up to 13,800 Nm
● Full torque already at standstill
● Extreme overload capability
● Best synchronous operation
● Liquid cooling with thermal encapulation
● Easy assembly
