针对多电飞机航空电源系统日益增长的用电需求，设计了一台额定功率为75 kW、额定转速为65 000 r/min的高速实心式永磁同步电机。此类高速电机运行速度快、损耗密度大，其设计受到多物理场的共同约束。通过有限元仿真，从电磁场、机械场和温度场三个角度对电机性能、转子强度和冷却系统进行了设计，并通过试验验证了设计的合理性。分析结果为多电飞机电源系统电机产品提供了参考依据。

In response to the growing demand for aviation power systems in multi-electric aircraft, a high-speed solid-core permanent magnet synchronous motor with a rated power of 75 kW and a rated speed of 65 000 r/min is designed in this paper. The type of high-speed motor operates at high speeds and has a high loss density, and its design is constrained by multiple physical fields. The motor performance, rotor strength, and cooling system are designed from three perspectives: electromagnetic field, mechanical field, and temperature field, through finite element simulation. And the accuracy and rationality of the design is verified by experimental results. The analysis results provide a reference for the motor products of the multi-electric aircraft power generation system.
