Single Phase Motors In case of a reluctance motor, when the load is increased so that it cannot maintain synchronous speed the motor will Run as induction motor Draw excessive armature current and may burn out Fall out of synchronism and come to stand still Become unstable Run as induction motor Draw excessive armature current and may burn out Fall out of synchronism and come to stand still Become unstable ANSWER DOWNLOAD EXAMIANS APP
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 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 then stop start and run at rated speed not start at all start and run slowly start and then stop start and run at rated speed not start at all start and run slowly ANSWER DOWNLOAD EXAMIANS APP
