【摘要】：提出一种绕组周向分布圆筒型初级永磁直线电机(tubular primary permanent magnet linear machine,TPPMLM)。与传统圆筒型初级永磁直线电机相比,该电机采用集中式绕组,每相绕组周向分布,初级铁心齿部及轭部由矽钢片一次叠压而成,初级制造工艺简单。同时,永磁体位于初级,次级仅由导磁铁心组成,可降低长距离驱动系统成本。该文阐述该电机的结构特点,给出工作原理,并分别利用磁路法及等效二维有限元法建立单元电机等效磁路模型及仿真模型,对静态特性分析,包括磁场、反电动势、定位力及电磁推力等。三维有限元模型及样机实验结果分别验证等效二维有限元模型的有效性及拓扑结构设计方法的正确性,同时,反电动势测试结果表明该拓扑不存在纵向端部效应导致的各相反电动势不对称问题。
[Abstract]:A winding circumferential distribution of cylindrical primary permanent magnet linear motor (tubular primary permanent magnet linear machine, TPPMLM). With the traditional cylindrical compared primary permanent magnet linear motor, the motor adopts the centralized winding of each phase winding of circumferential distribution of primary core tooth and yoke by a laminated silicon steel sheet a primary simple manufacturing process. At the same time, the permanent magnet in the primary, secondary only by the magnetic core, can reduce the cost of long distance driving system. In this paper, the structure characteristics of the motor, the working principle is given, and using equivalent magnetic circuit method and two-dimensional finite element method to establish the model and Simulation of motor unit equivalent magnetic circuit model. In the static analysis, including magnetic field, EMF, cogging force and electromagnetic force. The three-dimensional finite element model and experimental results verify the validity and topological structure are equivalent two-dimensional finite element model The correctness of the design method, at the same time, the result of the back EMF test shows that the topology does not have the opposite EMF asymmetry caused by the longitudinal end effect.
