| Abstract: | In order to improve the power density of the motor,a new type of directly cooled axial magnetic flux flux split-core non-magnetic yoke(YASA)motor was put forward.The three-dimensional CFD model of back-cooled YASA motor and direct-cooled YASA motor was established,and the steady-state three-dimensional temperature field and pressure loss of cooling system of the two motors were solved by finite element method(FEM).Finally,the optimized YASA motor was manufactured,and the simulation results were compared with the experimental results to verify the high efficiency of the motor cooling system. |
