摘　　要：针对大功率高速电机本身所固有的设计难度,开展多学科的综合设计,不仅考虑高速电机的电磁性能,还重点对转子强度、临界转速和冷却结构进行分析。通过设计500 k W、11000 r/min高速永磁电机,验证大功率高速电机的设计思路,并进行两台样机的试制和试验,进一步验证设计和分析的正确性。In view of the inherent design difficulties of high-power high-speed motors,an overall multidisciplinary design is carried out,which not only considers the electromagnetic performance of highspeed motors,but also focuses on the analysis of rotor strength,critical speed and cooling structure.Through the design of a high-speed permanent magnet motor of 500 kW and 11000 r/min,the design idea of high-power high-speed motors is verified,and two prototypes are produced and tested to further verify the correctness of the design and analysis.
