Abstract
The paper investigates the estimation of induction motor average temperatures within different parts under various operating conditions. An efficient thermal network model is developed and used to determine the thermal behavior under steady and transient conditions. It is observed that the computed mean steady state temperatures of the machine parts at no-load, rated load and blocked rotor operations compare satisfactorily well with the measured steady state temperatures.
