Single Phase Motors The rotor slots, in an induction motor, are usually not quite parallel to the shaft because it 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 helps the rotor teeth to remain under the stator teeth improves the efficiency ANSWER DOWNLOAD EXAMIANS APP
Single Phase Motors A capacitor-start single phase induction motor is switched on to supply with its capa-citor replaced by an inductor of equivalent reactance value. It will start and run at rated speed start and then stop not start at all start and run slowly start and run at rated speed start and then stop not start at all start and run slowly ANSWER DOWNLOAD EXAMIANS APP
