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