对无铁同步圆柱气隙永磁联轴器的不同结构类型进行了研究。在这些结构中，径向和切向取向的磁体放置在无铁芯中。这些结构具有极小的惯性，在很多情况下具有重要优势。提出了一种计算此类联轴器转矩的有效方法。它基于平行六面体磁体之间作用力的解析公式。通过使用非线性优化方法确定每种联轴器类型以及每对极数的最优设计。对设计结果进行了分析。对不同结构类型进行了比较。讨论了极对数以及每个联轴器主要特征尺寸的影响。结果表明，同时使用径向和切向取向磁体的无铁联轴器结构是一种非常有利的解决方案。
Different types of structures for ironless synchronous cylindrical air-gap permanent magnet couplings are studied. In these structures, radially and tangentially oriented magnets are placed in ironless cores. The structures present a very small inertia and offer important benefits in many cases. An efficient method to calculate the torque of these types of couplings is presented. It is based on analytical formulas for the forces between parallelepipedical magnets. Optimal designs for each type of coupling and each number of pole pairs are determined by using a nonlinear optimization method. The design results are analyzed. The different types of structure are compared. The influence of the number of pairs of poles and of the main characteristic dimensions of each coupling is discussed. The results show that an ironless coupling structure where both radially and tangentially oriented magnets are used is a very advantageous solution.
