With a little more guidance from DIYELECTRICCAR.COM I wired it up to one of my 12V blocks.
I was a worried what to expect as i didn't even get a chance to test the motor before I handed it over to the engineers. But it spun to life.
The engineers took forever but did a fantastic job ... Not only did they make the coupler and adapter plate under their quote of $1500 but they also advanced the end housing, sourced a bearing that was missing and polished the rotor at no extra cost.
I supose my job was on the backburner while other work was completed ... Hey, if it saved me hundreds, I couldn't be happier.
Next is to get this sucker mounted in the car and design battery racks to go around it. So, lets start looking at welders.
