I am driving this car with PWM. Originally, I used a 72V Curtis motor controller, and then later I upgraded to an open source Open ReVolt controller.

are you going to control it using pwm ?? ... I have a similar project, with 2 motors from an old komatsu forklift 2.2kw each ..
thanks!

All jokes aside, a friend of mine has an electric car that uses a motor controller out of a subway car. It runs about 300 volts. I think he has 27 12V batteries in his car.

Good size motor but it sounds like the bearings have seen better days!? Hope I'm wrong but that's what comes to mind. Cool video.

There was a bearing retaining clip that was loose when this video was shot.
The bearings were actually in perfect condition. Once I tightened the clip back down, everything was perfect.

Hi there, nice vid, could I please ask just a few questions:
1. How much did you pay for that motor, how much should one expect to pay for a motor?
2. Did you figure out why it was running so many AMPS from a no-load start? Maybe it wasn't too high at all, the very good Agni motors run around 6 amps or more from no-load speed.

I paid $50 for the motor. Motors from just yards are often just sold by weight of scrap value. I've seen similar motors at junk yards for $100 or less.
As for amps, I think it just wasn't a super-accurate ammeter. The armature of this motor weighs enough that one should expect it to pull a few amps with no load otherwise.

@Downfacingdog Been running my car on it for about three years now. Seems to be doing fine.
