Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFIf the air gap of an induction motor increases,
1) The permeability of the magnetic circuit rotor-to-stator will decrease.
2) The magnetizing inductance of the motor thus decreases.
3) The magnetizing current will increase; This will cause a poor power factor at all loads.
4) The magnetic flux in the air gap will decrease and leakage fluxes will increase; This will cause a reduction in the maximum available torque.
