永磁弧形导轨电机的电磁场参数化优化

Magnetic Field Parametric Optimization of Permanent Magnet Arc Guideway Motor

针对普通电机在特定角度范围内往复运动应用的不足,提出了一种新型永磁弧形导轨电机,其具有结构简单、工作可靠、效率高等特点。从永磁体的充磁方式和螺线管线圈的通电方式入手,在参数化的偏转角度下,对比分析5种不同充磁方式及通电方式。结果表明,永磁体横向磁化能够提供给电机同一方向的持续电磁力,其他磁化方式都不能达到该要求。横向磁化时通电方案五的X向平均电磁力是通电方案1时的7.3倍,横向磁化时通电方案5的合力电磁力相比通电方案2时平均提高了近162.6%。由此可知,横向磁化与通电方案5可有效提升永磁弧形导轨电机的电磁力和动态响应性能,具有一定的实际意义。

Based on the application drawback of the conventional motor reciprocating within certain angle, a new permanent magnet arc guideway motor was put forward, which has advantages of simplification, reliability, high efficiency, etc. According to the magnetization modes of permanent magnet and the modes of solenoid coil powered on, under the deflection angle of parameterization, five different magnetization and five different powered on modes were analysed. The results show that the permanent magnets magnetization in the transverse can provide continuous electromagnetic force, while the other modes of magnetization can not meet the requirement. The mean electromagnetic force in x direction magnetized in the transverse at proposal 5 is 7.3 times of that at proposal 1 ; the resultant of electromagnetic force magnetized in the transverse at proposal 5 is higher nearly 162.6% than that at the proposal 2. It can be seen that the transverse magnetization and the proposal 5 can effectively enhance the electromagnetic force and dynamic response performance of permanent magnet arc guideway motor, and provid with certain practical significance.
