双层Halbach阵列平面电机磁场分析
|
摘要
在制造过程中,对机械设备的要求越来越高。精密机械设备通常要求具有多自由度、高精度、高动态响应性能,优良的输出特性,高推力密度等特点。传统的滚珠丝杠结构已逐渐不能满足精密加工的需要。直接驱动移动平台也称平面电机,受到广泛关注。目前,平面电机的设计和制造技术还不够成熟,输出功率较低,行程较短,不能满足现阶段的制造要求。文中提出了采用双层二维Halbach磁阵列的平面电机。与现阶段的研究结果相比具有高气隙磁密,高输出能力等特点,为现阶段的研究提供了一种新思路。
In the manufacturing process,the requirements for mechanical equipment are getting higher and higher. Precision machinery usually requires many degrees of freedom,high precision,high dynamic response performance, excellent output characteristics, high thrust force density and so on. The traditional ball screw structure is gradually unable to meet the needs of precision machining. Direct drive mobile platform,also known as planar motor,has received wide attention. At present,the design and manufacturing technology of the planar motor are not mature enough,the output power is low,and the stroke is short,which cannot meet the requirements of the present stage of manufacturing. A two-level two-dimensional Halbach magnetic array planar motor is proposed in this paper. Compared with the present research results,it has the characteristics of high air gap magnetic density,high output capacity and so on. It provides a new way of thinking for the present research.
