I want to build motor controler

Postby movingturtle » Sat Jul 28, 2007 12:06 am

I am converting a Yamaha 750 motorcycle to plug in electric. Is there any source for schematics for pulse-width modulation motor controlers in the 48 volt, 400 amp range for an Advanced DC motor #A00-4009? I will use a 5 ohm handle bar throtle.
Alternative....good place to buy one cheap.
Thanks for your help

Try searching around for the Open Source Motor Controller project. It's intended as a robot controller for Robot Wars robots, but could be used in smaller EVs too. The project home page is based on a Yahoo group.

I wanna build too.
I need 120V about 200A for DC motor.
Simple and sheap.
OSMC not for me - its only up to 60V
And I think, what is not good idea use many mosfets in paralel ( more 4-5)

If you are set on building your own check out this site. Cost £12 to become a full memeber but they do have some very interesting projects.
