The power developed by a synchronous motor will be maximum when the load angle is
A. zero
B. 45°
C. 90°
D. 120°
Answer:C
The power developed by a synchronous motor will be maximum when the load angle is
A. zero B. 45° C. 90° D. 120°
Explanation: The maximum power developed in the synchronous motor will depend on rotor excitation (Ef), supply voltage(V), and the maximum value of coupling angle (δ).
