Explanation: The torque acts in such a direction as to align the two MMFs Fs and Fr and thereby reduce the angle λ between them. 3. Which of the following statements are correct regarding the torque equation in non salient pole machines, Te =-(P/2)(μoΠrl/g)(FsFr)sinλNm?
A. stator experiences less torque than rotor and in opposite directions
B. rotor experiences less torque than stator and in same directions
C. stator and rotor experiences equal and opposite torques
D. stator and rotor experiences equal torque and in same directions
Answer:A
