轴向磁通永磁同步电机（AF-PMSM）使用印刷电路板（PCB）绕组吸引了人们的兴趣，因为越来越多的机器与更薄的几何形状的需求。设计这些机器的一个关键因素是PCB绕组的选择，这应确保高性能特性，并有效利用PCB表面。然而，在关于不同PCB拓扑结构的性能的知识方面存在差距。这里报告的研究是出于需要比较常见的波形PCB绕组定子拓扑结构。因此，重叠平行波，非重叠径向波和重叠径向波PCB绕组拓扑结构进行评估，使用有限元分析，并根据其关键性能特性，如产生的反电动势，电感和电磁转矩进行比较。然后选择并制造提供最佳扭矩生产的PCB绕组。对样机进行了实验验证。
Axial-flux permanent magnet synchronous machines (AF-PMSM) using printed circuit board (PCB) windings are attracting interest because of an increased demand for machines with thinner geometries. A critical element in designing these machines is the choice of its PCB winding which should ensure high-performance characteristics with an efficient use of the PCB surface. However, there is a gap in the knowledge regarding the performance of different PCB topologies. The research reported here is motivated by the need to compare common wave-type PCB windings stator topologies. Accordingly, overlapping parallel wave, non-overlapping radial wave and overlapping radial wave PCB winding topologies are assessed, using finite-element analysis, and compared based on their key performance characteristics such as the generated back-electromotive forces, inductances and electromagnetic torque. The PCB winding that provides the best torque production is then chosen and manufactured. Experimental tests on the prototyped PCB AF-PMSM provide validation.
