Variable Speed Drives



Variable speed drives control the speed of an electric motor electronically. These drives are available for both DC and three-phase motors. DC drives are becoming less popular as AC variable speed technology has advanced. 

AC variable speed drives can also take in single-phase power and drive  3-phase motors. This is possible with smaller motors, approximately 10 HP and under.

Caldwell Electric is a distributor for the following lines of drives:

  • AC Tech / Lenze
  • Weg
  • Worldwide Electric
