Abstract
This paper presents an improved 2-D analytical model to predict the magnetic field distributions and torque characteristics for a flux focusing disk-type permanent magnet eddy current coupling. Due to the inhomogeneous physical properties in the permanent magnet regions, based on the equivalent magnetic circuit method, a fictitious magnetization for the iron cores is introduced to simplify the complexity of modeling. The magnetic flux density distributions are derived when the eddy current generated in the copper plate and its back iron is reasonably concerned in 2-D Cartesian coordinates. Then, the explicit expression of torque is given and the torque-speed characteristics are analyzed. In the end, the calculated results of the proposed model are compared with those obtained from the magnetic equivalent circuit model and 3-D finite-element simulations.
