An AC motor is classifies into . Ions contain CHARGES that create electric fields. These opposite electric fields produce imbalanced forces necessary to move the charges through the circuit. The phase relation between the rotor and stator magnetic field (i.e. the load angle) must be always greater than 0° in order to keep the motor in motion . THE ELECTRIC MOTOR AND ITS APPLICATIONS.

A 3-phase stator is wound with coils that are connected to produce the three separate phases, A, B, and C. During motor manufacture, an insulating material called slot paper is first laid in the slot to provide protection and electrical insulation.
