Eludium space modulator wanted, for an earth shattering BOOM!

Need a circuit diagram and a component list to build a Pulse Width Modulation speed control for a 48 volt six horse power DC motor. Come on folks... you are the brightest people I know....... Help?
(Why you ask? Because I need one..... details will follow later. It's all perfectly legal, trust me!)

If it's LEGAL, then forget it!

If I am one of the smartest people you know, you are in serious freaking trouble!

Why PWM? an AC motor with a freq drive will be torquier and cheaper to run, unless the DC motor in question cannot be easily replaced.

have you looked at ebay? Reliance Electric used to make awesome DC drives with a lot of very useful features.

Og, I have a 'go-cart' project I am working with some students on. It has a 48v 6hp DC motor direct fitted to a differential. It's what we have to work with. Any funds to build this monstrosity are coming from my pocket. I have to work with what I have.

Besides, no one else has one, and it's kewl.

Try here:

There's a lot of other info, but the PWM circuits themselves start conveniently on the page titled "P":

Thank you! I will check it out.
