AC Motors
Based on the characteristics of an electric current flowing, the AC motor consist of two types, namely:
1. AC electric motor / ac 1 phase
2. AC electric motor / ac 3 phase
The working principle of AC Single Phase Motor
Auxiliary winding currents I auxiliary graphs and the main winding currents I main different phases of φ, this was due to differences in the two turns of the impedance magnitude. This phase shift between the current difference causes the total current, is the vector sum of the main flow and auxiliary flow. The main magnetic field produced by the main winding phase is also different for φ with the help of magnetic field.
Z1-Z2 auxiliary winding energized first I auxiliary produce perpendicular magnetic flux Φ, moments later the main winding U1-U2 I main energized primary. which has positive value. The result is a magnetic field shifted by 45 ° with counterclockwise direction. This went on until one cycle sinusoid, resulting in a rotating magnetic field on entanglement stator.
Rotor single phase motors with three phase motor rotor is shaped wire rods which are connected shorted edges and resembles the form of a squirrel cage, hence often called squirrel cage.
Cut by the rotor winding turn the stator field, resulting induced voltage, the interaction between the field and turn the stator magnetic rotor will rotate in the rotor produces torque.

The working principle of AC Single Phase Motor
Single phase AC motor different is how it works with three-phase AC motor, where the three-phase AC motors for winding stator there are three turns of the play and the resulting field in the rotor cage induction and interactions occur which generate rotation torque. Whereas on single phase motor has two stator winding, which is the main phase winding (winding U1-U2) and the auxiliary phase winding (winding Z1-Z2), see figure.
The main turns of copper wire using a larger cross section, so have the impedance is smaller. While the auxiliary winding is made of copper coil with small diameter, so the impedance is bigger than the main winding impedance.
