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 »
The WEG CFW700 Series was designed to exceed industry expectations. Based on the robust CFW11
platform the CFW700 is designed and optimized for variable torque applications such as pumps and fans.
The CFW700 is the optimal drive for pump and fan control. The drive includes features such as built in PID
controllers that can be programmed in engineering units for ease of understanding and set up. The drive
also features an integrated power supply to be used with external transducers to measure flow or pressure.
These features combined with the drive's keypad based start up guide, make installation and parameter
set up fast and easy.

Notes:
Sizing the drive
The correct way to select a VFD is to
match its output current with the motor
rated current. However,
this listing also presents the expected motor
horsepower for each VFD model. Use the
motor power ratings only as a guide. ALWAYS compare motor FLA to Nominal AMPS of drive.
Motor rated currents may vary with speed
and manufacturer. IEC motor powers are
based on WEG 4-pole motors, NEMA
motor powers are based on NEC table
430-150.
