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 improves the efficiency helps the rotor teeth to remain under the stator teeth improves the power factor helps in reducing the tendency of the rotor teeth to remain under the stator teeth improves the efficiency helps the rotor teeth to remain under the stator teeth ANSWER DOWNLOAD EXAMIANS APP
Single Phase Motors In case of a reluctance motor, when the load is increased so that it cannot maintain synchronous speed the motor will Draw excessive armature current and may burn out Fall out of synchronism and come to stand still Run as induction motor Become unstable Draw excessive armature current and may burn out Fall out of synchronism and come to stand still Run as induction motor Become unstable ANSWER DOWNLOAD EXAMIANS APP
