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 »
CFW10 Variable Frequency Drives IP20 Finger-Safe Enclosure – With Potentiometer
General Information
The WEG Digital CFW10 VFD Series is a very small, easily mounted
package,simplified keypad and bright LED readout, complete
diagnostics and fully programmable I/O. The CFW10 controls three
phase AC motors with a single phase AC input. Single phase 120V
AC input voltage will produce three phase 230V to drive motors up to
1 HP and single phase 230 Vac will produce three phase 230V to
drive motors up to 3 HP. Increased flexibility and decreased costs
are achieved by eliminating the need for a step-up transformer to
operate three phase 230 Vac motors when only single phase 115V is
available. The CFW10 is an economical solution to many industrial
and commercial applications.

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.
