【Abstract】 In this paper,various cooling methods test of Shenzhen motor/generator were demonstrated using the similarity simulation test. The cooling effects of different ventilation structures were analyzed by data comparison,and then a reasonable cooling method was selected for Shenzhen motor/generator. Additional,based on the simulation test,the fluid field feature was acquired,which provides the boundary condition for temperature calculation. Using the finite element calculation method,the temperature distribution of Shenzhen motor/generator is studied,by which the cooling effect of the motor/generator is expected.更多还原
