| 摘 要： | 永磁电机由于齿槽效应造成的推力波动一直是影响其性能的一个重要因素.为了削弱永磁同步直线电机的齿槽转矩,结合直线电机的结构特点,利用能量法和傅立叶分解的解析分析方法,推导出了齿槽转矩与极弧系数的数学关系表达式.由于边端力也会造成直线电机的推力波动,而边端力与动子长度密切相关,提出了一种基于不同极弧系数组合的齿槽转矩削弱方...

| Abstract: | Force ripple caused by cogging force is one of the main reasons which prevent permanent magnet motors from acquiring high performance.Aiming at reducing cogging force in permanent magnet linear motors,taking into account of the structural features of linear motors,an analytical method based on energy method and Fourier series was proposed to obtain the expression of cogging force which was related with pole-arc.End force,which was closely related with the length change of the secondary rod,can also cause fo... |
