KESSLER COOLMOTION®

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
