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 »
Leeson 575V AC Adjustable Speed Drive
SM VECTOR SUB-MICRO INVERTER
New Surplus
Benefits:
Sensorless Vector AC Drive delivers up to
200% starting torque and can control a
vector duty motor down to 1Hz at full
output torque!
The SM-Vector drive is designed for operation
with vector duty rated induction motors rated
for 200, 230, 400, 460, or 590VAC from 0 to
240Hz.
IP20 enclosure with finger safe terminals
Easy setup and operation – Program the SM-Vector drive one of
four different ways:
– From the front of the drive
– The optional remote keypad
– A PC using the TechLink Software
– The EPM Programmer
Auto Tuning determines key performance values based on
the motor and installation variables. Required for operation in
vector modes, but can be used to enhance performance in V/Hz
mode.
The SM-Vector drive is an approved thermal overload
protection device for single motor applications.
18 isolated terminals provide 5 logic inputs and 2 logic
outputs.
Two reference inputs allow for 4-20mA and either 0-10V or
bipolar –10 to +10V
