A variable frequency drive is an electronic device that allows you to start, stop, and control the speed of a three phase motor. It is also a motor starter as it is equipped with overload protection. Read more »
What is the difference between a 'new surplus' motor and a 'factory new' motor?
Our New Surplus electric motors and drives are new and unused overstock or discontinued items offered at lower prices and come with our 90-day warranty.
Factory New products are competitively priced and come with a manufacturers warranty.

Homeowners and hobbyist alike, who have lathes or milling machines with a 3 phase motor, usually don't have 3 phase power to operate. These VFDs (instead of using a rotary phase converter) can now be used to convert single phase power to 3 phase power. Read more »
