Electrial Engineering MCQ on Synchronous Motors

As load is applied to a synchronous motor, the motor takes more armature current because

  1. The back EMF Decreases causing an increase in motor current
  2. The increased load has to take more current
  3. The rotor by shifting its phase backward causes motor to take more current
  4. The rotor strengthens the rotating field causing more motor current

Correct answer: 3. The rotor by shifting its phase backward causes motor to take more current
