In a salient pole synchronous motor, the developed reluctance torque attains the maximum value when the load angle in electrical degrees is
- 0
- 45
- 60
- 90
Correct answer: 45
Solution
The developed reluctance torque in a salient pole synchronous motor reaches its maximum at a load angle of 45 degrees because this angle optimally balances the magnetic forces, maximizing the torque produced by the difference in reluctance between the rotor and stator.
