I have a 130vdc treadmill motor that I am going to make a controler for.

I was thinking H-bridge mosfet driver with following criteria: Fwrd,revers and braking. with feadback control to controler (mach2 is my current choice) and the motor I am using is a 2.5Hp continious duty 130vdc 18.5amp.

That being said, I know there are probably drivers out there for this app. but I would like to DIY for learning experience.

So for the only controlers on the market I have found in a doable price range are non feedback or have on board style feed back that is SOOO slow to react as to not be usfull, or have a price tag that is in the stratosphere.

There are serveral H bridge schematics on the net but so far the only ones that I have seen are for low power robotics, nothing on the scale I need.

Since I am relatively new to electronics design, any suggestions would be helpfull. And who knows if we all put enough suggestions (group) in we could probably put a good set of plans up for everyone to use.

My main weakness in design is not knowing the proper chips for this there are so damn many mosfets and mosfet controler chips out there it will take eons to sort through them.

thanks
