High all! I first visited this site about 6 months ago looking for a circuit to drive a fisher&paykel motor on a battery and then got caught up in making wind mills with my father-in-law. Now I would like to use a F&P motor to power something other than a washing machine. The motor resembles the brushless dc motor that they use in the electric push bike but electronics are needed can any one help?

Thanks for posting that link Karl, good to see someone's got a F&P to work well as a motor. I was part of a solar challenge team years ago and we used a F&P as the motor at first. The mistake we made was to replace the plastic F&P hub with a aluminium hub fitted with rare earth magnets. The stronger magnets created a lot of back EMF, and we couldn't get a controller to work reliably. We ran out of time and had to go for a DC motor and chain drive.

The best time to plant a tree was twenty years ago, the second best time is right now.

Been thinking about this sort of thing myself but with a slightly different slant,the front free wheeling hubs could be converted to drive a couple of F&P genny's.
I'd like your thoughts on that,plus a bigger shed to do things in.

I need to learn from the mistakes of others.
I dont have the time to make them all myself.
