I am trying to get (at least one) 2011 Polaris Ranger EV working. It appears to be a PMAC motor, and it runs off a 48V DC Pack - no boost circuit.
When I was testing Paul's AC Controller design, I ran a Siemens 3 phase AC motor off a 128V DC pack. I managed to test the over-current on Paul's AC Controller design. I can't remember what the current was - I'd have to look it up - but the controller tripped ... and it has 3 x 600V 600A IGBTs.

I know it works leaf motor on lower voltage , maybe half of power, maybe Ill be happy maybe not. .. other motors also i don't know how will work. .. and it is hard to get it. . I get warp 11 and i know i will be happy with resoult. 47kwh of battery will do de yob
