AC single phase capacitor start motor

There are two windings. The capacitor is in series with one winding. That gives a phase difference with the magnetic field in the other winding. That starts the motor turning. When it gets up to speed a centrifugal switch shuts off the starting winding.

a capacitor causes a phase change between the voltage and current in ac, when it is passed through it, its also resistive to ac. this results in the current leading the voltage by up to 90 degrees on exit, which can be used to get the motor up to within 75% of running speed, and a centrifugal switch then engages the run winding, this can be either capacitor start synchronous run, or capacitor start capacitor run, depending on the design of the motor. i am not aware of a capacitor start/stop motor.

The capacitor is used to simulate a second phase to get the motor going, once its going then the capacitor is out of the system.

Put capacitor in parallel with alternator coil. The reason of using capacitor is that it can be source of apprent power while motor is running and the effect is that it the motor can produce more real power.

You need to learn how to do your own research (using Google, Yahoo etc).
Also next time try to re-word the question (so it is not quite so obvious that you want us to do your homework for you :-) )
