Leeson DC VFD Drive Motors - Electric Motor VFD Replacement Drive Motors

Buy Leeson Variable Speed Drives for a quality product that is built to last for any industrial or commercial application, from HVAC to construction to manufacturing. Whether you are adding a drive to a pump, conveyor, or crane, Leeson Speedmaster motor controls provide an excellent range of features including:

  • Single phase and three phase input drives
  • Enclosures include open IP20 for drives that are installed in cabinets or clean rooms; or more protected NEMA 1 IP31, NEMA 4/12 IP54 and IP65, and NEMA 4X enclosures
  • Washdown drives with white food-safe epoxy finish or stainless steel cases
  • Pre-programmed parameters for fast and easy installation and set up
  • Compact inverters easily fit in cabinets and tight spaces
  • Remote keypads and braking kits for select units


When installing an adjustable speed drive, maintain adequate spacing around each unit for air flow. The motor should be located as close to the VFD as possible (100 feet or less). For applications where the motor is more than 100 feet away from the drive, a load reactor or dV/dt filter should be installed. As motor lead length increases, voltage spikes generated by the VFD’s output transistors become amplified, and may result in motor failure. Adding an output reactor or dV/dt filter reduces the spikes.
