Will the Altivar Drives run a single phase motor?

Published date: 06 March 2019

Issue:
Will the Altivar Drives run a single phase motor?

Product Line:
All Altivar drives

Environment:
n/a

Cause:
Wants to operate a single phase motor.

Resolution:
Schneider offers some drives that can use single phase input and operate a three phase motor.
Schneider drives are not designed for use on single phase motors.

Unlike 3 phases asynchronous motors with 3 balanced windings, a single phase motor is composed of 2 windings.  The first is the main winding which is used to generate torque and the second one is the starting winding which is used to start motor.  The wire section of these two windings is not same due to fact that winding does not see same value of current and not during same time.  So this load on our drive output is not balanced and will also unbalance current which can have an impact on the drive's IGBT. 

Use of our drives with single phase motors can result of damage on drives and/or the motors.
