永磁直线同步电动机初级绕组的磁势分析

Analysis of the Primary Windings Magnet Potential of the Permanent Magnet Linear Synchronous Motor

采用绕组函数理论与电流对称分量法结合的方法对具有端部半填槽的永磁直线同步电动机(PMLSM)初级绕组的磁势进行分析。PMLSM的电枢铁芯、初级绕组、永磁体结构断开所造成的边端效应、端部半填槽等问题的存在,导致PMLSM初级绕组边端磁势发生畸变。对PMLSM初级绕组磁势进行深入的研究,有助于PMLSM稳态特性和暂态特性的分析。

This paper presents winding function theory and symmetry element method to analyze magnet potential of primary windings of permanent magnet linear synchronous motor(PMLSM) with half-filled slot.There are end effect,half-filled slot,which caused by the armature,windings and the PM discontinuous on their structure leading to change heavily for magnet potential of the end of primary windings of PMLSM.Studying magnet potential of the end of primary windings of PMLSM steady state and transient performance of PMLSM is available to be analyzed.
