| 摘 要： | 直线永磁开关磁链电机(LFSPM)适合长次级直线驱动场合,这是由于永磁体和电枢绕组都在短初级,而长次级结构简单可靠性高。很多应用场合都要求电机具有高推力,但往往也需要低的推力脉动。为此,对1台双边C型铁心的直线永磁开关磁链电机(DSLFSPM-C)进行研究和改进。利用有限元软件先对电机进行推力优化,然后为了在不影响平均推力的情况下有效地减小推力脉动,分别利用次级错齿和端部永磁体两种结构对电机进行了改进。分析结果表明,改进后的DSLFSPMC具有相对较低的法向力、高的推力输出以及较低的推力脉动。

| Abstract: | The linear flux switching permanent magnet (LFSPM) motor were capable for long secondary application due to that both the PMs and armature winding were on the short primary, in addition, the secondary was simple and robust. For this kind of machine, high average thrust force was highly desirable, however, low thrust force ripples were also required. A doublesided Ccore LFSPM (DSSLFSPMC) motor was investigated and improved. After being optimized for optimal thrust force using Maxwell 2D, this machine was improved to suppress the thrust force ripple without the decrease of the average thrust force based on a staggered secondary teeth structure and two end PMs. The analysis results showed that the improved DSSLFSPMC machine exhibits relatively low normal force and high thrust force as well as low thrust ripple, indicating that they were suitable for longstroke applications. |
