目的——近年来，随着永磁直线同步电机（PMLSM）的普及，温升越来越受到人们的关注，因为绕组中产生的过多热量可能会恶化电磁性能。为了解决这个问题，采用水冷系统是一种有效的方法。本文的目的是研究一种12槽/11极(12S/11P)水冷双面PMLSM，它采用全齿绕集中绕组和移位电枢端。设计/方法/途径——基于二维有限元分析（FEA），研究连续工作条件下的热性能，如温度分布、水流量优化和退磁影响。然后计算带或不带水冷系统的 PMLSM 的最大电流密度和平均推力。最后对单面PMLSM和双面PMLSM进行了详细的比较。发现...
Purpose – With the popularization of permanent magnet linear synchronous machines (PMLSMs) in recent years, the temperature rise has attracted increasingly attention since excessive heat generated in the windings could deteriorate the electromagnetic performance. In order to solve this problem, adopting water-cooled system is an effective method. The purpose of this paper is to investigate a 12-slot/11-pole (12S/11P) water-cooled double-sided PMLSM, which adopts the all teeth wound concentrated winding and shifted armature ends. Design/methodology/approach – Based on 2D finite element analysis (FEA), the thermal performances, such as temperature distribution, the optimization of water flow rate and the influence of demagnetization, are investigated under the condition of continuous duty. Then the maximum current density and average thrust force are calculated for PMLSMs with or without water-cooled system. Finally, the detailed comparison is made between single-sided PMLSM and double-sided PMLSM. Findings...
