Effects of Rotor Air-gap Eccentricity on the Power Factor of Squirrel Cage Induction Machines

Abstract- A substantial portion of induction machine faults is eccentricity related. In this paper, we have studied the power factor variation of induction machines due to the static and dynamic eccentricities. According to this study, air-gap asymmetry leads to inductance coefficient variations and, consequently, induction machine power factor variation. Experimental results are also provided to verify the simulations
