The in-wheel motors used in the electric vehicles must meet requirements such as high power density and high torque density.The analysis of the electromagnetic field and the temperature field for the in-wheel motors is crucial.A surface mounted permanent magnet in-wheel motor with fractional slot winding was taken as the analysis prototype in this paper.According to the electric machine theory, the harmonic of the magne-tomotive force of the winding was analyzed.The mathematical models of the electromagnetic field and the temperature field were established.The coupling simulation was solved by CAE software and the results were verified by the experimental tests.
