论文摘要
实验研究了两个旋转球形磁体的耦合。对于输入轴和输出旋转轴之间的两个特定角度，观察到无齿的耦合，其中驱动的磁铁被循环到驱动器上。这两种操作模式之间的惊人差异是驱动磁铁的旋转旋转感。对于其他角度，实验揭示了更复杂的动力学行为，该行为分为三个不同的类别。这是通过分析与驱动磁体的周期性运动的偏差以及测量该旋转的总谐波失真来完成的。实验结果可以通过基于纯偶极 - 偶极相互作用的数学模型来理解，并增加了足够的摩擦项。
The coupling of two rotating spherical magnets is investigated experimentally. For two specific angles between the input and output rotation axes, a cogging-free coupling is observed, where the driven magnet is phase-locked to the driving one. The striking difference between these two modes of operation is the reversed sense of rotation of the driven magnet. For other angles the experiments reveal a more complex dynamical behavior, which is divided in three different classes. This is done by analysing the deviation from a periodic motion of the driven magnet, and by measuring the total harmonic distortion of this rotation. The experimental results can be understood by a mathematical model based on pure dipole-dipole interaction, with the addition of adequate friction terms.
