If the rotor of a single-phase motor is rotated in one direction by some mechanical means, it will continue to run in the direction of rotation. ![]() What is basic method to start single phase induction motor and why it is not preferred? Consequently, the alternating flux cannot produce rotation in a stationary squirrel-cage rotor. The field polarity reverses after each half cycle but the field does not rotate. The single-phase stator winding produces a magnetic field that pulsates in strength in a sinusoidal manner. Why single phase induction motor does not self starts? ![]() Unlike a 3-phase induction motor, a single-phase induction motor is not self- starting but requires some starting means. ![]() What is major difference between a 3-phase induction motor and a single-phase induction motor?
