Re: CIM Motors in a non-FRC environment

Ether,
We tried using my high current linear power supply (35 amps continuous, 65 amps peak) to demonstrate an FP motor but the supply kept going into current foldback on start. The problem is the high start current drops enough voltage across the transformer windings, that the supply gives up. I did not want to add additional caps in the filter circuits since it was not worth it to step start the supply for a demo.
