Answer / hemalatha

due to increase of air gap stator current gets increased in
turn which causes decrease of power factor..

Answer / manishsingh

air gap high = leakage flux high = mutual flux low = X high = pf low = torque low

generally we put .5mm airgap in IM

Answer / kapil bhatt

SINCE THE TORQUE DEVELOPED IN THE MOTOR DEPENDS ON THE AIR
GAP ALSO, INCREASING THE GAP WILL GIVE US A LESSER TORQUE
BECAUSE THE MAGNETIC FIELDS OF STATOR AND ROTOR WILL NOT
STRONGLY CLUTCH TOGETHER THEREBY GIVING US A LESSER SPEED.
