Abstract

Dual three-phase permanent magnet linear synchronous motor (DTP-PMLSM) is widely used in linear motion system due to its low thrust ripple, good fault-tolerance performance and high system reliability. In the dual-three-phase winding structure with a 30° phase-shift, the winding magnetomotive force (MMF) harmonics that have the greatest impact on the motor’s thrust performance are significantly reduced. However, for the DTP-PMLSM with the pole-slot combination of |Q-2P| = Q/3, Where Q is an even multiple of 6, the electrical angle between adjacent electromotive force (EMF) vectors in the slot EMF star diagram is 120°, meaning the phase-shift between two sets of windings is restricted to 0°. This configuration increases harmonic content in the motor’s MMF. Therefore, this paper proposes a modular primary winding structure to redistribute the winding arrangement, ensuring that the phase-shift angle between corresponding windings is 30°. The structure effectively eliminates the 5pth and 7pth harmonics in the MMF and significantly reducing thrust ripple. Finally, finite element simulations are conducted to compare the thrust performance of the motor, validating the effectiveness of the proposed modular structure in reducing thrust ripple.

低推力脉动双三相永磁同步直线电机的模块化绕组

双三相永磁直线同步电动机（DTP-PMLSM）具有推力脉动小、容错性能好、系统可靠性高等优点，在直线运动系统中得到了广泛的应用。在相移为30°的双三相绕组结构中，对电机推力性能影响最大的绕组磁动势（MMF）谐波显著降低。然而，对于极槽组合|Q- 2p | = Q/3的DTP-PMLSM，其中Q是6的偶数倍，槽电动势星图中相邻电动势矢量之间的电角为120°，这意味着两组绕组之间的相移被限制为0°。这种配置增加了电机MMF中的谐波含量。因此，本文提出了模块化一次绕组结构，重新分配绕组排列，保证相应绕组之间的相移角为30°。该结构有效地消除了MMF中的5pth和7pth谐波，显著减小了推力脉动。最后，进行了有限元仿真，比较了电机的推力性能，验证了所提出的模块化结构在减小推力脉动方面的有效性。

期刊介绍： The Journal of Magnetism and Magnetic Materials provides an important forum for the disclosure and discussion of original contributions covering the whole spectrum of topics, from basic magnetism to the technology and applications of magnetic materials. The journal encourages greater interaction between the basic and applied sub-disciplines of magnetism with comprehensive review articles, in addition to full-length contributions. In addition, other categories of contributions are welcome, including Critical Focused issues, Current Perspectives and Outreach to the General Public. Main Categories: Full-length articles: Technically original research documents that report results of value to the communities that comprise the journal audience. The link between chemical, structural and microstructural properties on the one hand and magnetic properties on the other hand are encouraged. In addition to general topics covering all areas of magnetism and magnetic materials, the full-length articles also include three sub-sections, focusing on Nanomagnetism, Spintronics and Applications. The sub-section on Nanomagnetism contains articles on magnetic nanoparticles, nanowires, thin films, 2D materials and other nanoscale magnetic materials and their applications. The sub-section on Spintronics contains articles on magnetoresistance, magnetoimpedance, magneto-optical phenomena, Micro-Electro-Mechanical Systems (MEMS), and other topics related to spin current control and magneto-transport phenomena. The sub-section on Applications display papers that focus on applications of magnetic materials. The applications need to show a connection to magnetism. Review articles: Review articles organize, clarify, and summarize existing major works in the areas covered by the Journal and provide comprehensive citations to the full spectrum of relevant literature.
