Magnetic Couplings with Cylindrical and Plane Air Gaps: Influence of the Magnet Polarization Direction.
By
Progress In Electromagnetics Research B, Vol. 16, 333-349, 2009
Abstract
This paper presents a comparison of cylindrical and plane air gap magnetic couplings in which the tile permanent magnet polarizations can be either radial or tangential or axial. The expressions of the torque transmitted between the two rotors of each coupling are determined by using the coulombian approach. All the calculations are performed without any simplifying assumptions. Consequently, the expressions obtained are accurate and enable a fast comparison between the structures presented in this paper.
