Abstract: Various loss analysis models were established based on the operating condition of the drive motor for microvan. Combined with the established model and finite element software, the motor copper loss, iron core loss and eddy current loss of permanent magnet were calculated, and the temperature distribution of the motor under the structure of shell water cooling could be further obtained. The calculated results were in good agreement with the experimental results, which verified the accuracy of the calculation process of loss and temperature rise. The intelligent optimization algorithm was used to optimize the electromagnetic and waterway structure parameters by adopting the magneto-thermal coupling method. Compared with the initial motor scheme, the overall performance of the motor was improved after optimization.

Key words: permanent magnet motor, loss model, structural temperature rise, multi-objective optimization
