在低至中等功率额定无刷电机中，电磁源的噪声通常比机械和空气动力源的噪声占优势。永磁同步电机的磁极和槽缝的合理组合是影响其性能的关键之一，而降低噪声是其关键之一。本文针对分布式重叠式和单层集中式非重叠式绕组结构进行了研究。选择的组合是8极48槽(8p48s)、8p72s、46p48s和50p48s。通过二维有限元分析得到了气隙磁通密度，为计算电磁压力提供了依据。然后作为定子的机械和声学3-D有限元模型的输入。
In low- to medium-power-rated brushless machines, noise of electromagnetic origin is generally prevailing over mechanical and aerodynamic sources. The appropriate combination of pole and slot of a permanent magnet synchronous motor is one of the keys to its performances among which stands noise reduction. This paper investigates configurations regarding this aspect for distributed overlapping and single-layer concentrated nonoverlapping winding configurations. Chosen combinations are 8 poles 48 slots (8p48s), 8p72s, 46p48s and 50p48s. The air-gap flux density is obtained by 2-D finite element analysis (FEA), allowing to compute the electromagnetic pressure. It then serves as input of mechanical and acoustical 3-D FEA models of the stator with carter.
