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 increased load has to take more 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 back e.m.f. decreases causing an increase in motor current The increased load has to take more current The rotor strengthens the rotating field causing more motor current The rotor by shifting its phase backward causes motor to take more current ANSWER DOWNLOAD EXAMIANS APP
Synchronous Motors In a synchronous motor it the back e.m.f. generated in the armature at noload is approximately equal to the applied voltage, then the torque generated is maximum the excitation is said to be zero per cent the motor is said to be fully loaded the excitation is said to be hundred per cent the torque generated is maximum the excitation is said to be zero per cent the motor is said to be fully loaded the excitation is said to be hundred per cent ANSWER DOWNLOAD EXAMIANS APP
