Hello friends
Short time ago I have finished my cnc router and started to learn how to work with it.
My first project was unusual very simple 3 phase brushless motor .
I got this motor design idea long long time ago so I had simple and "useful" project
for my cnc learning and at the same time testing if my idea is working .
Rotor and stator was cut from 1,5 mm hard aluminium sheet , coils core cut out from
old transformator and to the rotor I glued strong magnets.
Assembled engine runs better than I thought.

Hello
I have not try it as generator because in the motor mode coils are wound up
with thick wire and small numbers of wire windings around coil core.
For generator is needed to rise number of wire turns to rise output voltage.
Battery voltage is transformed to 3 phase with AC brushless speed controller
for rc model motors see yellow box connected to the motor.
have a nice day.

I have build a lot of motors with various number of coils and magnets
so I have many drawings .
Anyway if there are people interested in doing motor I would provide
plans .

Thanks for the answer Kadora, and congratulations for this engine.

I'm actually gathering ideas for an electric generator to be driven by one of my steam engine, hence my question, as 3 phase engine looks promising for such use...
