LCI rating/Motor rating Mismatch
LCI rating/Motor rating Mismatch
(OP)
Let's say I have a 1 MW LCI Drive but for some reason I want to drive a small synchronous motor, let's say 50HP.
The LCI drive is designed for an input of 1kV but only 480V is available. For the sake of this scenario assume that I can change undervoltage parameters, maximum current parameters etc. Also assume that on the field side I can reduce the current to the correct value for a 50 HP motor.
What are the pitfalls? One I can think of is that the feedback from the stator may not have enough magnitude to allow for correct commutation.
Any other issues? Or can it just not be done?

Any other reason why this might not work?
