cyber® kit line large – frameless servo motors

  • cyber® kit line large – Frameless servo motors

  • cyber® kit line large – Frameless servo motors in size 290, 360, 420 and 530 mm

high torque – highly integrated – flexible

The frameless servo motors of the cyber® kit line product family offer maximum torque and flexibility in a compact size. In addition, the frameless design with a large hollow shaft gives the highest possible freedom of integration to develop unique solutions for specific applications. The assembly kit, consisting of rotor and stator, can be flexibly integrated into the machine thanks to the variety of variants. 

Furthermore, the high-performance direct drives (torque motors) are the ideal solution for e.g. applications within machine tools.
