In an induction motor if air gap is increased

WebIf the air gap is increased, it will offer high resistance to magnetic flux and the stator will draw more magnetizing current from the supply to maintain the required flux in the air gap to the rotor. This will reduce the power factor of an induction motor or … WebWhen air gap eccentricity exists in a motor, the air gap flux will be off balance, causing different levels of voltage to be induced onto the rotor. This results in irregular current …

Induction Motor - an overview ScienceDirect Topics

WebAn induction motor draws more magnetizing current as compared to the magnetizing current drawn by the transformer. This is because the reluctance of the magnetic core of the motor is more as the air gap between the stator and the rotor offers more reluctance. How to calculate the inductance of the coils in a 3-phase motor? WebWith increased air gap, the increased reluctance of magnetic circuit, and the magnetic current consumption would be increased with more leakage flux. Would consumed more … crystal lam york pa https://deanmechllc.com
