摘要

为了提升燃料电池空压机用高速永磁同步电机的功率密度和安全性，提升散热性能，设计了复合冷却系统，基于有限元和CFD软件建立了电磁-热双向耦合平台，在此基础上优化了高速永磁电机冷却系统，保证其在适宜温度工作并同时提升电机性能。优化后的高速永磁电机最终电流幅值为25 A，提升66.7%；电机最大功率为17 kW，提升70%；转矩最大达到1.48 Nm，提升66.3%；绕组最高温度约为381.8 K，降低52.4%；永磁体最高温度约为404.9 K，降低32.3%。

Abstract

In order to improve the power density

safety and heat dissipation performance of high-speed permanent magnet synchronous motor for fuel cell air compressor

a composite cooling system was designed

and an electromagnetic-thermal bidirectional coupling platform was established based on finite element method and CFD software. On this basis

the cooling system of high-speed permanent magnet motor was optimized to ensure that it worked at a suitable temperature and improve the motor performance. The final current amplitude of the optimized high-speed permanent magnet motor is 25 A

which is increased by 66.7%. The maximum power of the motor is 17 kW

which is increased by 70%. The maximum torque is 1.48 Nm

which is increased by 66.3%. The maximum winding temperature is about 381.8 K

which is reduced by 52.4%. The maximum temperature of permanent magnet is about 404.9 K

which is reduced by 32.3%.
