摘要
对具有多极、少齿结构的永磁直线伺服电动机(PMLSM)进行了分析和计算。在设计上采用真分数槽绕组和开口槽对齿槽磁导波进行移相调制,并优化了电枢长度,有效削弱了PMLSM的端部效应和齿槽效应,提高了伺服机构的定位精度。利用有限元法计算了直线电机在不同位置的Detent Force及其在矢量控制下不同负载时的推力波动。
A permanent magnet linear servo motor(PMLSM) with topology of many poles and few teeth has been analyzed and calculated.A winding of proper fraction slot and the open slot has been adopted in the design to modulate the cogging permanence and optimize armature length,which can effectively restrain ending and cogging effect of PMLSM to improve the position precision of servo system.The finite element method is used to calculate the Detent Force at different position and ripple of thrust at the different load ...
