- W4384347144 abstract "In the field of permanent magnet synchronous motors (PMSMs) cooling, turbulent kinetic energy (TKE) and turbulent dissipation (TD) are used for the first time to numerically evaluate the heat transfer performance of axial water jackets (WJs), in order to investigate the influence of the WJ's structural parameters on the water-cooled system of high-power-density permanent magnet synchronous motors (HPD-PMSMs). In the present work, the temperature distribution and fluid flow pattern of a 40kW HPD-PMSM were calculated using the finite element method, and temperature testing of the HPD-PMSM at different speeds using a built test platform. In addition, the effects of the bend shape of cooling channels (BSCC) on the axial WJ's performance for heat transfer are examined, and a detailed analysis of the mechanism underlying the development and evolution of high vorticity vortex is provided. The findings demonstrate that the TKE is attenuated by the positive vortex development, which is harmful to the TKE's normal function in axial WJ heat transfer. Furthermore, the maximum stator winding temperature was reduced to 93.49?C and the maximum flow velocity within the WJ could be increased by 14.34% owing to the BSCC improvement." @default.
