What is a Variable Frequency Drive?
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 »

WEG Starter Replacement Cross-Reference

WEG has upgraded its ESW, ESWS, PESW and PESWS enclosed magnetic starters from the older CWM contactor to the new CWB contactor. Find your old starter below to see its exact CWB replacement, matched by series, coil voltage, control devices and overload range. Need help? Call 800-469-3110.

How the Part Numbers Changed

The new part number adds a B (CWB contactor) and uses a new coil code. Overload ranges are identical.
Coil codes: V18 → D15 (120V)  ·  V24 → V24 (208–240V)  ·  V47 → D39 (480V)  ·  V56 → D45 (600V)  ·  V04 → D02 (24V)
