Experimental investigation of the dynamic behaviour of cogging-free magnetic clutches

无齿槽磁力离合器不会出现任何有关紧密性的问题，因此非常适用于流体的混合和输送。日常生活中的例子包括牛奶泡沫和洗衣机的泵。在抽象理论考虑的基础上，即纯粹的偶极子-偶极子相互作用，最近讨论了一些几何不同的磁性单离合器和多离合器，理论上它们应该是无齿槽的，没有任何残留的纹波，因此应该运行得非常平稳和低损耗。我们希望根据这些理论思想构建真正的离合器并进行实验研究，i)它们是否完全工作，ii)残余纹波将是什么以及iii)这种离合器在负载下如何动态工作。

Cogging-free magnetic clutches do not show any problems concerning tightness and therefore are very suitable especially for mixing and the transport of fluids. Examples in everyday life include milk frothers and pumps in washing machines. On the basis of abstracting theoretical considerations, i. e. a pure dipole-dipole interaction, recently a number of geometrically different magnetic single and multiple clutches were discussed, which in theory should be cogging-free without any residual ripple and thus should run very smoothly and with low losses. We would like to build real clutches according to these theoretical ideas and investigate experimentally, i) whether they work at all, ii) what the residual ripple would be and iii) how such clutches work dynamically under load.
