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 revolves synchronously it can be easily manufactured in extremely small sizes of up to 1 W output it is not subject to any magnetic or mechanical vibrations it develops hysteresis torque which is extremely steady both in amplitude and phase it revolves synchronously it can be easily manufactured in extremely small sizes of up to 1 W output it is not subject to any magnetic or mechanical vibrations ANSWER DOWNLOAD EXAMIANS APP
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 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 improves the power factor improves the efficiency ANSWER DOWNLOAD EXAMIANS APP
