Explanation: In an electrical machine, armature winding is one in which the working emf is induced by the working flux. 10. Why is the air gap between stator and rotor should be kept as small as mechanically possible in induction motor?
A. to reduce the leakage flux between stator and rotor
B. as it leads to better operating power factor of the induction motor
C. reduce the eddy current losses
D. both, to reduce leakage flux between stator and rotor, and also for better operating power factor
Answer:A
