build an electronic driver

Dear, FreeLancer.

My name is Romani S., messaging you from Egypt.

Me and my friends are looking to build an Electric motorcycle which is powered by a 7.5 KW three phase AC motor.

The power source that we do have is 3.7 V(DC) lithium batteries.

We do wonder if you can help us with a driver that we can use to convert the the DC source to a 3 phase AC source with the tool to change to motor speed.

Thanks in advanced

Romani S. Elkommos

I already read the description. Your idea is feasible. But not optimized. I think a better way is use a DC motor and used battery direct power it.
