Single Phase Motors The rotor slots, in an induction motor, are usually not quite parallel to the shaft because it improves the power factor improves the efficiency helps the rotor teeth to remain under the stator teeth helps in reducing the tendency of the rotor teeth to remain under the stator teeth improves the power factor improves the efficiency helps the rotor teeth to remain under the stator teeth helps in reducing the tendency of the rotor teeth to remain under the stator teeth ANSWER DOWNLOAD EXAMIANS APP
