The torque angle, in a synchronous motor, is the angle between_______________?
Correct answer: C. the rotating stator flux and rotor poles
- A. the supply voltage and the back e.m.f.
- B. magnetising current and back e.m.f.
- C. the rotating stator flux and rotor poles
- D. none of the above
Explanation
The torque angle is the angular displacement between the rotating stator flux and the rotor field axis or rotor poles. This angle determines the electromagnetic torque developed by the motor.
