Kessler Torque motor

Motors MOTORS

KESSLER sets new standards with one-stop direct drive system solutions

We provide a wide range of asynchronous, synchronous, torque and linear motors,
plus individually customized solutions.


The target merging of expertise into a core area focussing on motor technology, gives us the advantage of enhanced knowledge and the ability to bring together decisive components to form a powerful and comprehensive direct drive system.

This enables KESSLER to utilize specific branch-related cycles for the continual development of its products and to make future-oriented and pioneering technology available for a wide variety of application areas.

Direct drive system with torque motor

KESSLER is the innovation engine behind state-of-the-art direct drive technology and is renowned for powerful and energy-efficient motors with high torque density and top reliability even in high-demand applications. Practically-based simulations and individual customer calculations are a prerequisite for the development excellence of KESSLER motors.


The inverter-optimized COOLMOTION® motors are recognized for their low-loss design and enhanced heat dissipation. Innovative modifications of the motor components have enabled us to reduce the rotor and stator losses by 25%. Special construction measures have resulted in significantly enhanced heat dissipation.

The COOLMOTION® technology optimizes efficiency to a maximum.

COOLMOTION® in drive technology
  • achieves a very high torque density with up to 30% more torque in a minimized design
  • facilitates a compact design
  • achieves a significantly more robust design in relation to resonance and reflection effects
  • facilitates applications even during continuous loads
  • provides maximum standstill torque
