- Energy savings on centrifugal loads
- 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.
