摘　　要：针对永磁直线同步电机推力波动大的明显缺点,提出了一种新型的双三相永磁直线同步电机,完成了双三相永磁直线同步电机在d-q坐标系下的数学建模,重点研究了双三相永磁直线同步电机的运行特性,最后通过Ansoft有限元方法(FEM)进行了验证,仿真实验证明了理论的正确性,研究结果为双三相永磁直线同步电机设计理论及控制策略有着指导意义。For the obvious shortcoming of great thrust ripple of permanent magnet linear synchronous motor, a novel du- al three-phase permanent magnet linear synchronous motor was proposed. The mathematical model of the dual three-phase permanent magnet linear synchronous motor in the rotary reference frame was determined, and operating characteristics of it was studied. Finally the finite element method was adopted to verify it. The simulation experiment results show that the method is correct and effective, the conclusion can be used to guide design considerations and control strategy of dual three -phase permanent magnet linear synchronous motor.
