cyber® kit line small – frameless servo motors

  • cyber® kit line – servo motors in size 50 and 85 mm

  • Different lengths per size with two mass inertia optimized hollow shaft variants

  • Can be used with integrated temperature sensors and optionally with Hall sensors

  • Compatibility to cyber® simco® line servo drives

  • Optional encoder module with BiSS-C, SSI, incremental and Hall interface

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 additional, the frameless design with a large hollow shaft gives the maximum possible freedom of integration to develop unique solutions for specific applications.

The cyber® kit line assembly kit consisting of rotor and stator can be flexibly integrated into the machine thanks to the variety of variants.
