hello!
i got a 5kw 3phase AC motor I want to use it for a small cart but the problem is that i cant find a system that regulates voltage before the inverter, is that even necessary? i was thinking of using the adjustable frequency inverter alone hooked to the battery which means that i can only change the frequency but not the voltage. I've read something about flux increasing and making the motor heat up when the frequency is really low at lowspeeds if you dont lower the voltage.
or should i go from dc to ac then to a controlable rectifier back to dc(to contral voltage) and then to the inverter(to control frequency) then to the motor? :S
any suggestions would be apritiated
