| Abstract: | In order to study the temperature distribution of hub motor, three-dimensional finite element model (FEM) of a hub motors was established, the winding structure was analysised, the related theory of heat transfer is used to modeling of winding and insulation materials. the equivalent model of double-layer windings is presented, and the equivalent thermal conductivity of the windings of the hub motor is calculated by using this model, and the temperature field of the windings is calculated accurately by using the finite element method. Finally, a bench test is carried out on the hub motor, and the accuracy of the model is verified by simulation and test. |
