化纤用两极稀土永磁同步电动机的启动性能研究

Design of two-pole rare-earth PMSM used in fiber industry

在化纤用两极永磁同步电动机设计中,电机的启动问题较为突出.重点研究了电机设计参数对电机启动性能的影响,并在此基础上设计了一台高性能的化纤用两极稀土永磁同步电动机,最小转矩倍数大于1,牵入转矩倍数大于0 8,具有良好的启动性能.

The prominent design problem in two-pole permanent magnet synchronous motor (PMSM) lies in its starting problem.In this paper,the influence of design parameters on motor's starting is analyzed,and then,based on this research,a high performence two-pole PMSM used in fiber industry is design.The minimum torque multople is more them the toggling torque multiple is bigger than 0.8 and having a good starting capality.
