Wow, Is it hot in here  ;)

I don't want to get into the argument so I'll just answer the original questions.

I was looking to use a VNH3SP30-E as is it a H-Bridge device that makes things easier but it was not powerful enough for me. I'll now be making my own h-bride. Its a lot more effort, but I'll gain good experience and it will do what I want.

Hero999 was very helpful to me in working out what to do.

I had some custom software from these guys, but they also do electronics.

PWM adjustable from low frequency to MHz wont be cheap though. Not sure it is even possible in any realistic way. 0Hz to 100kHz might be more reasonable.
