Magnet-Motor was founded in 1980 by the German physicist Dr. Götz Heidelberg. Even at that time, the focus of the company's activities was on the development of novel and powerful electrical machines for the propulsion of vehicles. In doing so, the company always used young technologies that had just reached the industrial society at that time from powerful rare-earth magnets to water cooling and the patented flux compression for new, exemplary compact, electrical machines.

In 2021 Magnet-Motor was taken over by RENK GmbH and incorporated into the group as RENK Magnet-Motor GmbH.
