In a synchronous motor, the maximum power developed depends on all of the following except:
Correct answer: C. direction of rotation
- A. rotor excitation
- B. maximum value of coupling angle
- C. direction of rotation
- D. supply voltage
Explanation
The maximum power is proportional to the supply voltage and rotor excitation voltage and occurs at a coupling angle of 90 degrees. It does not depend on whether the machine is rotating clockwise or anticlockwise.
