New Winding Technology

This extremely short hollow shaft planetary gear unit includes a large internal bore of either 28 or 38 mm, allowing for reliable feeding of power cables, hydraulic hoses and pneumatic pipes.

The compact design of the motor is based on a new winding technology that is said to generate the highest possible copper fill factor. This measure increases the motor rating by about 80% compared to conventional winding technology and has made it possible to reduce the length of the motor accordingly. The rigid output drive bearing of the gear unit provides a high level of tilting support, allowing high tilting moments to be applied. Optional liquid cooling is available to increase the nominal torque.
