simple question all i want to know is what a ac motor is and how it functions?
The most common type of AC motor is the 'Squirrel Cage' motor. This has what appears to be a solid rotor, but is actually copper or aluminium bars embedded in steel. The electricity rotates around these bars, producing a rotating magnetic field,which pulls the bars, and so the rotor, around with the field. The power supply needs to be more than 1 phase, but a single phase supply can fool the motor into thinking it is 2 phases, by using a capacitor connected in series with one set of the motor windings.
An AC motor is an electric motor that runs on alternating current, used in most homes and businesses. There are several different types, e.g .induction motor, squirrel cage, universal, 3-phase. Try wikipedia. The basic principle is electric coils generating magnetic fields which push on other coils to make them turn.
