The slim and space-saving shaft-mounted helical geared motors are a simple plug-on drive unit and optimized for 120 Hz operation on a frequency inverter.

The energy-efficient, inverter-optimized MF three-phase AC motors are particularly suitable for tasks that demand large setting ranges with minimal sizes. Thanks to the shaft-mounted helical gearbox, they have high permissible radial forces, closely stepped ratios and low backlash.


  • Slim shaft-mounted gearbox in a compact design
  • Shaft dimensions in line with market standard and standardized flanges
  • Coordinated drive system with i550 motec frequency inverter
