END WINDING LEAKAGE CALCULATION OF A SQUIRREL‐CAGE INDUCTION MOTOR FOR DIFFERENT LOAD CONDITIONS

Authors:

Abstract
The calculation of the end winding leakage of a squirrel‐cage induction motor using a three‐dimensional finite element method is discussed. The end winding inductance is thought to consist of a leakage, describing the flux linked with the end winding only, and a mutual part, describing the flux linked with both end winding and end ring. Both leakage and mutual inductance are found to vary for different load conditions.
