Abstract
In the preceding related paper (Part 1), the authors presented expressions for finding the eddy current, braking force and damping coefficient on the rotary magnetic damper, consisting of one sector magnet and a circular conductor, and investigated the validity of the constant flux assumption for the magnet. This paper extends the analysis of the authors' previous report to the problem of the rotary magnetic damper, consisting of several sector magnets and a circular conductor with a circular cavity. Numerical calculations have been carried out for the dimensionless damping coefficients with variations of factors, such as the flux range, the radius of the circular cavity of a circular conductor, the position and the number of the magnets. The characteristics of the rotary magnetic damper have been investigated in detail ; especially the optimal values of the damping coefficient have been clarified.
