摘　　要：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65000 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 65000 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.
