The system specifications should be considered in the practical design of linear machines, albeit mostly neglected in the previous studies. The main objective of this article is to propose a systematic design method of a coreless-type permanent magnet linear synchronous machine (PMLSM), satisfying all the constraints resulting from the system specifications. Based on the trapezoidal motion profile, an electromagnetic design model is developed by utilizing the 2-D field solutions and energy conversion principle. The thermal effects are incorporated into the design model by measuring the hot-spot temperature of the static winding coil, thereby setting the upper limits of current density. The differential evolution (DE) is then applied to the design model to search for optimal solutions without violating any of the constraints. As a result, the proposed model combined with DE provides the Pareto-optimal front belonging to the feasible regions where all system specifications (e.g., acceleration profile, maximum speed, maximum allowable temperature, load mass, and supply voltage) are satisfied. Finally, the validity of the design model is verified by both the finite element (FE) and experimental results.

考虑系统规格的直线永磁电机集成设计方法


尽管在以前的研究中大多被忽视，但在线性机器的实际设计中应该考虑系统规格。本文的主要目的是提出一种无芯型永磁线性同步电机（PMLSM）的系统设计方法，满足系统规格产生的所有约束。基于梯形运动曲线，利用二维场解和能量转换原理开发了电磁设计模型。通过测量静态绕组线圈的热点温度，将热效应纳入设计模型中，从而设定电流密度的上限。然后将差分进化 (DE) 应用于设计模型，以在不违反任何约束的情况下搜索最佳解决方案。因此，所提出的模型与DE相结合提供了属于可行区域的帕累托最优前沿，其中满足所有系统规格（例如，加速度曲线、最大速度、最大允许温度、负载质量和电源电压）。最后，通过有限元（FE）和实验结果验证了设计模型的有效性。
