Can anyone tell me where to get a simple description of what is happening during the various parts of the induction motor speed-torque curve? I have found some info using equivalent circuits, but:
a. I don't need anything that precise
b. It's been forty years since I graduated and longer than...
I recently heard that the OLR must be "resized" if a PF capacitor is connected on the load side of the OLR. Ref: NEC 430.22 and 460.9
Has anyone done this? I can't find a way to calculate. However, I have always placed the capacitor ahead of the OLR.
