| 摘 要： | 介绍了定子双馈电双凸极电机(SDFDS)的结构、原理和弱磁调速控制方法。相对于永磁电机,定子双馈电双凸极电机磁场可调,易于实现弱磁控制和基速以上的恒功率控制,大大扩大了电机的调速范围。针对一台三相12/8极定子双馈电双凸极电机,运用Matlab/Simulink软件建立仿真模型,实现该双凸极电机的恒功率弱磁调速,从而说明电机有调速范围更宽的优点。

| Abstract: | In the paper,the structure,operation principles and flux weakening control methods for the stator doubly-fed doubly salient(SDFDS)motor are introduced.Compared with permanent magnet motor,its magnetic field can be regulated.Hence it is easy to realize flux-weakening control in SDFDS motor,and in turn greatly extending the constant power operation range.By using Matlab/Simulink,modeling for a 12/8-pole SDFDS motor is drveloped and the simulation analysis is carried out.The results show that the much wider constant operation range can be achieved by the flux weakening control. |
