A linear oscillating motor is an electromagnetic actuator that can achieve short-stroke reciprocating movement directly without auxiliary transmission mechanisms. It has been widely used in linear pump applications as the source of power and motion. However, because of the demand of high power density in a linear actuation system, the performance of linear oscillating motors has been the focus of studies and deserves further research for high power density. In this paper, a general framework of linear oscillating motor design and optimization is addressed in detail, including the electromagnetic, dynamics, and thermal aspects. First, the electromagnetic and dynamics characteristics are modeled to reveal the principle for optimization. Then, optimization and analysis on magnetic structure, resonant system, and thermal features are conducted, which provide the foundation for prototype development. Finally, experimental results are provided for validation. As a whole, this process offers complete guidance for high power density linear oscillating motors in linear pump applications.

单边直线感应电机(SLIM)因结构简单牢固,直接产生前进的电磁推力,在交通中得到广泛应用。 由于其磁路断续,电机运行中存在横向和纵向边缘效应;次级的入口和出口因气隙磁链守恒原理会产生涡流, 并随速度上升而加大。边缘效应和涡流大小对直线电机气隙磁链产生重要影响,造成气隙有效磁通和牵引力系 数降低。探讨直线电机工作特点,得到了电机d-q轴等效电路,通过d轴互感和电阻变化来实时反应第二纵 向边缘效应和次级涡流的影响。结合旋转电机转子磁场矢量控制方法,建立了对应的SLIM控制方程。采用转子 磁链、速度和电流三个调节器,提出了uds,uqs,iqs实时在线解耦补偿控制方法,对SLIM的推力、d-q轴电压、d-q轴磁链等进行调节和控制,对d轴互感大小进行限制。结果表明,该方法在电机速度突变时减小了力 矩脉动,定子电流过渡平滑,速度平稳,改善了SLIM的运行性能,为电机实际运行分析提供了理论依据。

Most of the XY positioning stages proposed in previous studies are mainly designed by considering only a single performance indicator of the stage. As a result, the other performance indicators are relatively weak. In this study, a 2-degree-of-freedom linear compliant positioning stage (LCPS) is developed by mechatronic design to balance the interacting performance indicators and realize the desired positioning stage. The key parameters and the coupling of the structure and actuators are completely considered in the design. The LCPS consists of four voice coil motors (VCMs), which are conformally designed for compactness, and six spatial leaf spring parallelograms. These parallelograms are serially connected for a large travel range and a high out-of-plane payload capacity. The mechatronic model is established by matrix structural analysis for structural modeling and by Kirchhoff’s law for the VCMs. The sensitivities of the key parameters are analyzed, and the design parameters are subsequently determined. The analytical model of the stage is confirmed by experiments. The stage has a travel range of 4.4 mm× 7.0 mm and a 0.16% area ratio of workspace to the outer dimension of the stage. The values of these performance indicators are greater than those of any existing stage reported in the literature. The closed-loop bandwidth is 9.5 Hz in both working directions. The stage can track a circular trajectory with a radius of 1.5 mm, with 40 mm error and a resolution of lower than 3 mm. The results of payload tests indicate that the stage has at least 20 kg out-of-plane payload capacity.
