考虑了基于高矫顽力稀土钴永磁体利用的同步转矩耦合器的设计。对于此类装置，通常要求在满足可能存在的任何设计约束条件下，用最小体积的磁性材料获得给定的转矩输出。对于这种优化配置，每单位体积磁性材料和内耦合器元件的最大转矩分别显示为\(5.6\times10^{-3}(B_{r}^{2}\bar{r}/\Delta)\)和\(10^{-2}B_{r}^{2}\)，其中\(\bar{r}\)是宽度为\(\Delta\)的间隙中的平均半径，\(\bar{r}/\Delta\gg1\)，\(B_{r}\)是剩余磁通密度。给出了此类优化设计的示例，并简要讨论了可能的替代设计标准。
The design of synchronous torque couplers based upon the utilization of high coercive force rare-earth cobalt permanent magnets is considered. For such units, it is generally required to obtain a given torque output with a minimum volume of magnetic material, subject to whatever design constraints may exist. The maximum torque for such optimized configurations is shown to be 5.6 \times 10^{-3} (B_{r}^{2}\bar{r}/\Delta) and 10^{-2}B_{r}^{2} per unit volume of magnetic material and inner coupler element, respectively, where \bar{r} is the average radius in the gap of width \Delta, \bar{r}/\Delta \gg 1 , and B r is the remanent flux density. Examples of such optimal designs are given and possible alternate design criteria are briefly discussed.
