The main requirements for a rotating electric machine are the torque/power density and the energy efficiency. Producing an efficient electric machine required not only studying and analysing the electromagnetic properties but also deeper thermal analysis. It has been found that attention to the thermal design can be improve the total machine performance. In this paper a thermal model of the two-layer and spoke-type ferrite interior permanent magnet (IPM) machines is developed. FEA models are built to run the thermal studies and temperature distribution of the machine under different operating conditions. A prototype machine is built and tested for the experimental validations of the FEA. A prototype machine is tested under various working conditions. The testing results validate analytical model and the FEA methods.
