Combined Electromagnetic and Thermal Analysis of Permanent Magnet Disc Motor

The paper presents a methodology for coupling electromagnetic and thermal phenomena in a permanent magnet disc motor performance analysis. Both the electromagnetic and thermal analysis is performed using two-dimensional finite element method (FEM). Due to the complex geometry of the disc motor a proper modelling of the motor is performed. The thermal analysis is performed based on the losses calculated from the electromagnetic FEM analysis, as well as the measured ones. To show the validity of the proposed method, a test bench is realised and temperatures in specific points are measured and afterwards compared with the calculated ones using FEM analysis.
