最近的研究表明，由于集中绕组的较高的磁动势谐波含量，这种机器类型的特点是低转矩能力和质量，以及低效率和热问题。本文提出了一种新的基波FSCW，具有正弦磁动势波形和非重叠的绕组布置。所提出的绕组解决方案包括两种不同的FSCW类型和双槽层定子结构。第一绕组位于外槽层区域上，而第二绕组位于内槽层区域上。另外，两个绕组在空间上彼此移位特定角度。这种绕组结构具有谐波含量低、端部绕组长度短、适用于低极点集成电路等优点。从不同的IM的分析结果表明，所提出的FSCW在不同的应用领域提供了高性能。
Recent investigations on IMs with FSCWs show that, due to the higher MMF harmonic content of concentrated windings, this machine type is characterized by low torque capability and quality, as well as, low efficiency and thermal problems. This paper presents a new fundamental wave FSCW with sinusoidal MMF waveform and a non-overlapping winding arrangement. The proposed winding solution consists of two different FSCW types and a dual slot-layer stator structure. The first winding is located on the outer slot-layer region, while the second one is located on the inner slot-layer. Additionally, both windings are shifted in space to each other for a specific angle. This winding configuration has several advantages like high quality MMF wave with low harmonic contents, shorter end-winding length, and applicability to low poles IMs. Obtained results from the analysis of different IMs show that the proposed FSCW provides high performances in different application areas.
