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 »
CFW08 WASH Variable Frequency Drives Wash Down - NEMA 4X Enclosure
General Information
The WEG CFW08 WASH Series is a redesign of our
successful uline VFDs. Engineering improvements
have produced one of the most compact and full
featured microdrives in the marketplace.
Outstanding features and options in a NEMA 4
enclosure allow the CFW08 WASH to be successfully
used in a large variety of applications.
Two programmable relay outputs (1NO, 1NC, 240vac 0.5A)
Two isolated programmable analog inputs (0-10V, 0/4-20mA)
Protective features: Over current, motor overload, drive over temperature,
output phase-to-phase and phase-to-ground short circuit, DC bus over
and under voltage and external fault
Control features: Linear and "S" ramp acceleration and deceleration,
local/remote control, DC braking, torque boost, motor slip compensation,
electronic pot, preset speeds, adjustable V/Hz profile, maximum and
minimum adjustable frequency limits, two skip frequencies, adjustable
output current limit, JOG, ride-thru, flying start and PID regulator.
Display readings: Motor speed, frequency, voltage, current, last fault,
heatsink temperature and drive status
Optional Features - Contact Dealers for Price & Availability
Dynamic Braking Resistors available
Remote Keypad with Copy Function
RS-232 or RS-485 Serial Interface
Modbus Communication*
DIN rail mounting through 2HP
*Requires optional RS-232 or RS-485 Interface
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.
