Product range


The power-optimized cyber® kit motors distniguish with their low no. of pole pairs
by a high overload capacity and low cogging. Espacially the combination of efficiency
and diversity abets the use in cusomized applications with requirements for maximum
integration and compactness.

Technical Data

Integration in the overall system

We simplify and speed up integration in your application.

Maximum efficiency and superior performance data in a limited space are typical requirements for frameless motors. We can help you achieve ideal integration in your system. We can modify the interface and/or scope of delivery to ensure reliable and cost-effective installation.

Independent integration

You take on the assembly. We help with the integration inter alia with insertion devices and training courses (e.g. magnetic bonding, shrink fitting).

Your advantages:

  • We minimize your risks by providing expert support
  • You increase your internal added value
  • We share our development & production expertise with you

Delivery of a ready-to-install system

WITTENSTEIN takes on the assembly: The assembling of our motors and the provided parts at WITTENSTEIN.

Your advantages:

  • You benefit from our experience in development & assembly
  • Ideal level of integration reduces your costs
  • Delivery of a ready-to-install assembly simplifies integration in your system
