• Soft start/stop to reduce mechanical stress

Frequently Asked Questions

How do I size a VFD to my motor?

Match the drive to the motor's full-load amps and voltage - not just HP. Oversized loads or high starting torque may need a larger drive.

Chassis or enclosed drive?

Chassis (open) drives mount inside your panel; enclosed (NEMA 1/12/3R/4) drives are ready to hang on a wall or run outdoors.

Will a VFD save energy?

On variable-torque loads like fans and pumps, slowing the motor cuts energy dramatically (roughly the cube of speed) - usually the biggest ROI in the plant.
