Single Phase Motors Hysteresis motor is particularly useful for high-quality record players and tape-recorders because it develops hysteresis torque which is extremely steady both in amplitude and phase it is not subject to any magnetic or mechanical vibrations it can be easily manufactured in extremely small sizes of up to 1 W output it revolves synchronously it develops hysteresis torque which is extremely steady both in amplitude and phase it is not subject to any magnetic or mechanical vibrations it can be easily manufactured in extremely small sizes of up to 1 W output it revolves synchronously ANSWER DOWNLOAD EXAMIANS APP
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 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 efficiency improves the power factor 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 efficiency ANSWER DOWNLOAD EXAMIANS APP
