Outline of Final Research Achievements

In case of using magnetic gears as transmission device, characteristics of magnetic force of the gears influence positioning accuracy. Therefore, the characteristics between magnetic gears are investigated. Their measurements for catching the characteristics are behavior by open-loop control, influence of gap between gears, step response by constant amplitude, and nonlinear spring behavior. In particular, the response is good because the stiffness is high if the gap is small. The positioning accuracy is good because the disturbance of magnetic force is small, if the gap is large. Nonlinear spring behavior shows same characteristic of linear motion ball bearing. There is possibility of influence of bearings.
