2 pole / 4 pole differences

VFD needs higher voltage than standard 50Hz motor (x4) and more current. Your are right. 104V is not about lowering the system voltage, it is about raising the performance (power to weight) well beyond the standard industrial 50Hz realm. Mind you 2x voltage and Tmax 3 =6 all up would be fine for no...

Ron"s EV stories

Hi ex-neighbor,until i read about Rons use of wet batts and not knowing he doesn't get winter i got my hopes up but i guess i'll go back to the idea of using AGM's.Yeah we very seldom have to worry about flesh freezes but those days do come occasionally.Now don't forget your sunscreen guys!

All in one Charger,Controller and DC to DC

No Richo,but just look at the guys controller and assuming he has done it then its doable,however it also appears he can handle a small village with all thats in that box.

2 pole / 4 pole differences

Would i be right in assuming that the above rewound 104v motor(in order to get the full benefits)would require a vfd and a much larger voltage to utilise the vfd?

2 pole / 4 pole differences

I would like to know (given that i had a small ac controller (say 500amp.72-120 volt and a 104volt motor,etc.) can i run this on 72,84,96 etc.volts?whats to be expected? Still striving for that bare bones efficiency/ transportation model.I apologise for how my mind works!
Thank you(s).
