摘要
设计了一种新型的磁悬浮直线开关磁阻电机系统,非常有潜能适用于高精度机械加工等领域。系统结构简单、坚固耐用、可直驱运动,磁悬浮结构几乎没有机械摩擦以及由此带来机械磨损、噪声和过热等问题。为了验证设计的磁悬浮直线开关磁阻电机系统的可行性,分别采用了磁路分析法和有限元法对其电磁力进行了分析,并且通过实验进行了验证,进而提出了对磁路分析法的改进算法。分析表明,改进的磁路分析法和有限元法的计算结果都能和实验结果保持一致,为磁悬浮直线开关磁阻电机的设计优化打下了基础,可以提供有用的参考。
A novel magnetic levitation linear switched reluctance motor was presented, which had the great potential to be applied to precise motion control of automation machines. The proposed system is simple, robust, and direct-driving. The levitation structure almost eliminates mechanical frictions so as to avoid mechanical wears, noises and heat generation. Magnetic circuit analysis （MCA） and by finite eement analysis （FEA） were both adopted to analyze magnetic force for val- idating the feasibility of the proposed system. Furthermore, experiments of magnetic force were performed with the actual hardware. Results of the MCA, thc FEA and the experiments were compared and analyzed, and the MCA was improved. The magnetic force analysis of the proposed system gives the basis of the system design methodology and can form useful ref- erences in the design of magnetic levitation linear switched reluctance motors.
