Thanks for your comment.

Firstly, regarding the AC motor, as I know, it is much more complicated to install compared to a DC motor. AC motor no doubt is more efficient, but the down side is its complexity.

In regards to the pot box, check out the video link below:

In regards to your regenerative braking system, it does not generate a lot of power to recharge the battery. But it does produce a small amount of power.

Should you do it?

That’s up to you actually. But it does require a lot additional work and parts. Moving parts have a tendency to fail.

There is a couple of questions I have that i hope you can answer for me! right now I have access to a ACmotor that I can buy new for $600.00 Canadian it’s a (see if I can recall correctly) 180/230V motor it looks like it has a controler built on to it ! it weighs in around 180lbs a cooling fav built in and sealed ballbearings and a 1″ keyed shaft ,

Would that be a good EV motor Its build for continuous operation and is 1,800 rpm.

Another question is : Hot does a potbox hook up to a AC 1,800 rpm motor through its controler ,and be able to effect the Motors speed?

I have a 1957 Morris Minor ,I am hoping to build it into a EV vehicle ,but this motors Higher voltage would take a lot of batteries for it to function properly! Yes?

As for a DC Motor I’ve seen some Motors that have the Armiture Shaft sticking out Both ends of the motor ! I thought it might be possible to run a couple of Automotive Alternators form a double pully off the back end of the motor!

When engaging the brakes the first movement of the brake peddle could trigger a switch that would make a contact to an old air conditioning pully engaging the 2 alternators connected with belts to the motors outer pully hopefully slowing the car a bit and charging power back to the batteries!!!!

That’s what I would try to do if i use a DC motor !!!

But how could a couple of Alternators produce enough Voltage to recover some power to that many batteries hooked together?? or is that an impossibility?
