摘　　要：音圈电动机在半导体制造装备、光学仪器、高精密机床等现代高精、高效加工装备以及在计算机硬盘等高端办公设备的部件中得到越来越广泛的应用。分析一种线圈为方形且作直线平动的音圈电动机的设计,首先推导出电磁推力与电磁结构的材料特性,以及几何参数之间的关系表达式;在此基础上,提出了此类电动机的一个比较系统性的设计方法与设计流程,其中包含了一些保证对象电磁特性、机械特性和热学特性的环节;此外,还讨论了电枢反应、运动反电势等关键问题的分析方法。Voice coil motors （VCMs） have been widely applied in modem machining equipment and office machines. The design problems of the lateral VCM with a rectangle coil are discussed. An equation describing the relation between the electromagnetic thrust , the motor dimension, and the performance of VCM material is derived. Based on the above equation, a systematic design procedure for lateral VCM with a rectangle coil is given. Some verifying operations for guaranteeing the electromagnetic, mechanical and thermal performances are included in the design procedure. In addition, the method of analyzing armature effect and the motion electromotive force is also discussed.
