vfd against electric motor

vfd against electric motor

(OP)
please guys I have a 40hp vfd needed to drive a 40hp electric motor ( load is actually less than what the electric motor can handle), my challenge now is that I don't have a 40hp electric motor but I have a 50 HP electric motor. please can the 40hp vfd drive the 50 HP electric motor?

RE: vfd against electric motor

That wouldn't be a problem at all. You just can't load the motor shaft fully.

If the difference had been larger, say a 50 HP motor and a 20 HP VFD, you would have problems with excitation, but not with this rather small underrating.
