About us ABOUT US

Integrate any direct drive into any environment

KESSLER energy GmbH operates within the KESSLER Group, using optimized assembly lines for the production of electrical drives.

KESSLER energy accompanies the product from the electrical and mechanical construction, to the numerical calculations using the finite element methods and analytical calculation programs to the testing, commissioning and parameter optimization of the end result. KESSLER motors meet the highest efficiency requirements.

The company also reinforces the drive technology expertise of the KESSLER Group in new application areas.

End-to-end precision from the
