Q.In electromechanical energy conversion devices (e.g generators and motors) a small air gap is left between the stator and the rotor in order to

  • Areduce the reluctance of the magnetic path
  • Bincrease flux density in the air gap
  • Cpermit mechanical clearance
  • Davoid saturation of field
Correct Answer : (C)

permit mechanical clearance

Hints :
