Real Time Temperature Measurement for the Thermal protection of Switched Reluctance Machine

Heat transfer is a critical aspect related to Electrical machine design. To insure a successful design of the electrical machine, special attention has to be given to thermal aspects in parallel with the traditional Electromagnetic design. For calculating the temperature rise in electrical systems such as electrical machines or power electronic systems it is important to measure the temperature rise in the motor winding .The common method has many shortcomings, therefore a new method for measuring the temperature rise is proposed in this paper. Rise in the winding temperature in an electrical machine namely Switched Reluctance Machine can be determined from the estimated values of winding resistance calculated during the heat run test . The results obtained for a 2 H.P Switched Reluctance Machine is validated with the temperature measured using Resistance temperature detector and Infra-red Camera.
