In this paper the thermal analysis and simulation of a squirrel-cage Asynchronous machine are presented. The algebraic and differential system of equations governing the steady and transient states thermal behaviour of the machine respectively are first represented in state variable form with temperature rise as state vectors and thereafter solved numerically with the help of commercially available software package, MATLAB©. It is observed that the computed average temperatures of the machine parts at no-load compare satisfactorily well with the experimental results.
