Characteristics Analysis of Noncontact Spinning Mechanism with Numerical Simulation
This paper analyzes the spinning characteristics of a noncontact spinning mechanism with numerical simulation. In this mechanism, when the suspended object is stably levitated in the vertical direction by a magnetic suspension system, the disk magnets spin the suspended object in the horizontal direction by means of the remanent magnetization on the surface of the suspended object. The disk magnets are arranged around the levitated object, and the magnetic poles are arranged in a parallel configuration. In this paper, the mechanism is introduced, and the remanent magnetization on the surface of the suspended object is examined using a gauss meter. A numerical model is set up, and the spinning characteristics are analyzed with a step input and its velocity in steady states conditions using different numbers of magnets.
