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.
Variable frequency drives (VFDs or inverters) now play an important part in major industry.
Within the last 10 years they have been perfected to control and vary the speed of 3 phase electric motors. They serve many purposes, besides speed control. 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 »
Toshiba’s definite purpose, totally enclosed fan cooled,premium efficiency, Vector Ready motor series is designedfor the extreme operational requirements of today’s variablespeed applications. This product line was built using thecornerstone of the Toshiba motor product offering, theEQPIII, as a base. It is built to survive in the most demandingenvironments requiring tight vector control such as materialhandling, conveyor, and machine tool as well as many otherprocess-oriented applications. The Vector Ready motor seriesis specifically designed for indoor and outdoor inverteroperation and is not intended for conventional across-the lineoperation. This product exceeds the requirements ofNEMA MG1 Part 31 Definite Purpose (inverter duty).
