Synchronous Motors As the load is applied to a synchronous motor, the motor takes more armature current because The increased load has to take more current The rotor strengthens the rotating field causing more motor current The back e.m.f. decreases causing an increase in motor current The rotor by shifting its phase backward causes motor to take more current The increased load has to take more current The rotor strengthens the rotating field causing more motor current The back e.m.f. decreases causing an increase in motor current The rotor by shifting its phase backward causes motor to take more current ANSWER DOWNLOAD EXAMIANS APP

Synchronous Motors If the field circuit of an unloaded salientpole synchronous motor gets suddenly open-circuited, then it runs at a slower speed it continues to run at the same speed the motor stops it runs at a very high speed it runs at a slower speed it continues to run at the same speed the motor stops it runs at a very high speed ANSWER DOWNLOAD EXAMIANS APP
