Hi Guys,

Thanks for the ideas, it is a great help! So I have a 230-110 transformer and the parts to rectify that after the drop down. I also have capacitors big enough to smooth this out. That part SEEMS to be simple enough (famous last words).

The pulse width modulation regulator on the other hand has me scratching my head again, i'm afraid....Can anyone give me a link to a module that might give me an idea of what i'm looking for?

I have used PWM with smaller motors using a micro controller to product the pwm and an H-bridge to control the power. Is that basically (although a much bigger version) what i am looking for?

Also, can i use a nice big shunt resistor to limit the current for the field winding, if there isn't enough resistance already? I have some pretty large ones knocking about from a servo motor braking circuit.....

My biggest fear here, if i'm being honest, is that i do something daft and damage the motor....It is not something I can afford to "scrap". If i can get all the parts together, can i "test" this with lower power to make sure i have a working solution before I go "full" power? Or is there any advice for this to make sure i don't do any serious damage?

Thanks again for all the help, any advice is greatly appreciated.


Cheers,

Mort
