Ceiling Fan to Wind generator conversion demo
That will turn that half wave rectifier into a full wave rectifier.
Finally, adding an additional capacitor as an 'input filter' before the rectifier input should totally smooth out that dc wave form.
The coils aren't wound clockwise, counterclockwise, clockwise, etc.. They should all be wound the same direction. There will basically be 2 circuits... one set of coils that is wired directly to the source voltage, and the other set is wired with the capacitor. They are set on the motor in an alternating pattern.. so the first coil will be in the capacitor circuit, the next without the cap, the next with the cap, the next without etc. The capacitor side of the circuit causes the current to lag 90 degrees out of phase with the other side of the circuit. This creates a rotating magnetic field. The rotating magnetic field moves past the squirrel cage in the stator, inducing a current in the squirrel cage. This creates a magnetic field in the squirrel cage that is opposite in charge to the magnetic field in the rotor, causing the stator to be attracted to the rotating magnetic field of the rotor. The stator will always rotate slightly slower than the rotating field in the rotor. This is called slip. This is because if the stator was moving at the same speed as the rotors magnetic field, than the bars of the squirrel cage would not be getting crossed by the rotors field, and no current or field would be produced in the stator. Now that you know how a single phase induction squirrel cage motor works, you can better understand and design a generator from its components.
