摘　　要：针对高速永磁同步电机的温升问题,以一台65 kW,12000 r/min电机为例,基于流体力学和传热学基本理论,采用CFD温度场仿真,对电机水冷结构的导热热阻对其散热性的影响进行分析,并提出在电机定子与水套之间填充导热硅脂以减小接触热阻的优化方案。通过样机实验测试,验证了该方案的可行性,为电机的冷却优化设计提供了依据。In order to solve the problem of temperature rise of high-speed permanent magnet synchronous motor,a 65 kW,12000 r/min motor was taken as an example.Based on the basic theory of hydrodynamics and heat transfer,CFD temperature field simulation was used to analyze the influence of heat conduction resistance of water-cooling structure of motor on its heat dissipation.The optimization scheme of filling heat conduction silicone grease between motor stator and water jacket was put forward to reduce contact resistance.Through the prototype test,the feasibility of the scheme was verified,which provides the basis for the cooling optimization design of the motor.
