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 »
FRENIC-Eco drives offer simple installation, quick start-up, easy maintenance, and functionality targeted specifically for variable torque fans and pumps. With functions like: PID with sleep mode, enhanced energy savings, low torque detection, overload avoidance, loss of speed reference control, cascade pump control, and communication protocols for both commercial and industrial facilities: the FRENIC-Eco series of drives are ideally suited for almost any variable torque application
