介绍了1 MW高速永磁同步电机无槽定子的制造工艺和质量评定方法。电动机的目标是达到13 kW/kg，装配有利用利兹线作为导体的成型绕组空心电枢绕组。目前正在开发一个原型，不久将进行全功率测试。详细讨论了定子绝缘、机械和热性能鉴定试验程序。结果表明，制造工艺和公差显着影响机器的性能。说明了这种无槽定子的各种组装挑战及其对性能目标的影响。
This paper discusses the manufacturing process and qualification procedures of a slotless stator for a 1-MW high-speed permanent magnet synchronous machine. The motor, targeted to reach 13 kW/kg, is assembled with form-wound air-core armature windings which utilize litz wire as the conductor. A prototype is being developed and a full-power test will be done in the near future. The insulation, mechanical and thermal qualification test procedures of the stator are discussed in detail. Results showed that the manufacturing process and tolerances significantly affect the machine performance. Various assembly challenges of this slotless stator and their impacts on performance targets are illustrated.
