Abstract
This paper analyzes the torque performances of two kinds of noncontact spinning mechanisms, which are the linear driving type mechanism and the rotational driving type mechanism. In these two noncontact spinning mechanisms, the suspension of the suspended object is realized in the vertical direction by a suspension device using a permanent magnet and a linear actuator, and the spin of the suspended object is realized by the variable flux field around the suspended object. The flux field is changed by the linear movement of permanent magnets in the linear driving type mechanism and by the rotational movement of disk magnets in the rotational type mechanism. In this paper, first, two kinds of mechanisms are introduced. Second, the suspended object is modeling and the experimental device is installed using the strain gauges. Finally, the rotational torque results of the two kinds of mechanisms are shown and discussed.
