lowest frequency output available from vfd
lowest frequency output available from vfd
(OP)
Let's say were were doing a brief test and were not concerned about cooling or other effects on the motor.
What is the lowest frequency output available from a typical 480v 60hz-input VFD?

It does edpend on the VFD, some VFDs will operate right down to zero, while others switch the output off at around 0.5 Hz. I think that youwill find that the vector drives that can providetorque right down to zero Hz will give you this performance, while the V/Hz drives will tend to give no output at zero.
