Variable Speed Motor Systems

Variable Speed Motor Systems

The RFE™ raises the bar in grid to shaft efficiency, cost and power quality. The RFE™ provides greater efficiency by independently controlling the rotor of a wound field motor and not controlling the power to the stator, eliminating the majority of switching losses, power quality and EMI. Not having a separate Variable Speed Drive and a simple design adds up to lower cost.

Our RFE™ technology will provide a cost effective, simpler more reliable variable speed motor system and improve your products. Contact us now to learn more.


Benefits of the RFE System for Variable Speed Applications:

  • No Separate Variable Speed Drive
  • Highly Efficient (up to 96%)
  • No Magnets
  • No Inverters
  • Lower Cost
  • More Reliable
  • Meets or exceeds all current regulations
  • Little or no EMI
  • Smaller system footprint
  • Quick turnaround for your customized prototype

With the RFE System we can achieve a more sustainable world.
