Great Kenbo !
Excellent idea to try it out with the bike.

As Alan also sais the great thing of your 36 pole machine is the low speed required to get a reasonable output, to experiment with.

Most big hydro electric powerstations run at very low speeds, 75, 100, 120 RPM with large diameter multipole alternators.

Keeping yourself fit and generating some electricity to drive your stereo or a couple of lights is more fun then putting your energy in a friction system, to dissipate the excess power, to make the bike exercise a bigger workout.

This motor is exactly the same principle as the one I have.

The hardest part is to center the rotor around the stator if you are not using the washing machine assemble i have found out.
Exact line up of all components is critical here.

Keep your project going and keep us posted mate.

Kind regards, Raymond


The product of rotation, excitation and flux produces electricty.
