Synchronous Motors As the load is applied to a synchronous motor, the motor takes more armature current because The back e.m.f. decreases causing an increase in motor current The rotor strengthens the rotating field causing more motor current The rotor by shifting its phase backward causes motor to take more current The increased load has to take more current The back e.m.f. decreases causing an increase in motor current The rotor strengthens the rotating field causing more motor current The rotor by shifting its phase backward causes motor to take more current The increased load has to take more current ANSWER DOWNLOAD EXAMIANS APP
Synchronous Motors A synchronous motor connected to infinite bus-bars has at constant full load, 100% excitation and unity power factor. On changing the excitation only, the armature current will have leading power factor with under-excitation leading power factor with over-excitation lagging power factor with over-excitation no change of power factor leading power factor with under-excitation leading power factor with over-excitation lagging power factor with over-excitation no change of power factor ANSWER DOWNLOAD EXAMIANS APP
