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 »

Standard Features

  • Same programming as all other WEG VFD's
  • Plug and play philosophy (connect and use) enables quick and easy installation of accessories and options.
  • USB for microcomputer connection for using SUPERDRIVE programming and monitoring software as well as updating inverter firmware.
  • Human-Machine Interface (HMI) with backlit graphic display and soft-keys, greatly facilitates inverter programming and operation.
  • DC link inductors (symetrically connected to positive and negative DC link terminals) enable compliance with IEC61000-3-12 standard requirements regarding harmonics, (no need for external line reactance.)
  • Intelligent thermal management enables full protection of IGBTs, monitoring of heatsink and internal air temperature.
  • Conformal coated circuit boards.
  • 50°C Ambient
  • Automatic control of the heatsink fan with speed sensor (additional protection) and easily detachable from the unit for cleaning and maintenance.
  • Normal Duty and Heavy Duty ratings to adapt optimally to all kinds of loads.
  • Protection with failure and alarm warnings.
  • Motor overload protection in compliance with IEC 60947-4-2 | UL 508 C.
  • Memory card built into the standard product allows user to create functions without the need to use an external PLC (soft-PLC via IEC61131-3 programming software)
  • Guided start-up simplifies initial user programming.
  • Real time clock with time and date stamped fault log.
  • TRACE / SCOPE function to assist with the start-up and system diagnostics.
  • SuperDrive G2 compatible

Optional Features - Contact Dealers for Price & Availability

  • Safety stop in compliance with EN 954 - 1/category III**
  • External control feed with 24 Vdc
  • RFI filter in compliance with EN 61800-3 (internal)**
  • DB Resistors and line/load reactors available upon request, call Dealers for price & availability

Applications

  • Pumps
  • Fans/Blowers
  • Conveyors
  • Compressors
  • Agitators and Mixers
  • Extruders
  • Grizzly Feeders
  • Centrifuges
  • Cranes and Hoists
  • Rollout Tables
  • Presses
  • Saws

Notes:

    Normal Duty (ND) Cycle:
    • 110% for 60 seconds every 10 minutes
    • 150% for 3 seconds every 10 minutes

    Heavy Duty (HD) Cycle:
    • 150% for 60 seconds every 10 minutes
    • 200% for 3 seconds every 10 minutes

    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.
