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 increased load has to take more current The rotor by shifting its phase backward causes motor 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 increased load has to take more current The rotor by shifting its phase backward causes motor to take more current ANSWER DOWNLOAD EXAMIANS APP
