Potting Compound

In the field of electric vehicles, the high power density demand for the permanent magnet synchronous motor (PMSM) has made the thermal management a great challenge, especially the end winding. For enhance the heat dissipation for end winding, Aluminum Nitride (AlN) potting compound is introduced. Numerical simulation is performed in this paper to evaluation the effect of usage of potting compound. A prototype motor is built up with the end winding filling with the proposed potting material. Experiment shows that the heat dissipation has improved compared with the baseline motor.
