Re: AC electric motor rewinding for EV use

Hello
How much peak power would a 50 Hz 7.5kW 4 pole motor with 400 V windings produce with 48 V battery and custom rewind to lower voltage at 75 Hz ?
to what voltage should I rewind it?
I want to convert small tractor to EV, max speed is 2300 rpm.
thank you
