Abstract According to the fluid mechanics and heat transfer theory, taking the main propellant direct-drive permanent magnet motor (PMM) of electric vehicle (EV) as the object of study, physical and mathematical models of coupling solution to a 3D fluid flow and heat transfer are established under the strong cooling condition for the structure characteristics and ventilation performance of EV main drive PMM. Using finite element method for coupling calculation of three-dimensional fluid field and temperature field, the flow performance of internal fluid in motor, the characteristics of heat transfer performance, and the distribution of insulation temperature rise of motor and winding are analyzed, and the results are compared with the test, which provide a theoretical basis for the temperature field research and selection on heat load of main propellant PMM of EV.
