Abstrakt: Performance of Squirrel Cage Induction Motor (SCIM) used in Electric Vehicles (EV) is fluctuating due to temperature rise and has impact on torque production. The effect of temperature rise on torque behavior in SCIM necessitates an analysis as it finds diverse applications in EV's. Core loss causes variation in temperature rise to torque ratio characteristics. The core loss at different loads is computed from average maximum flux density obtained from FEM analysis. The relative percentage error for change in 3/4th to full load is decreased to 2.6% when the variable core loss is used for prediction of temperature rise in SCIM. Considering variable core losses, the operating torque range of the SCIM for EV application is extended until full load condition from 3/4th load condition. [ABSTRACT FROM AUTHOR]
