Study on the Eddy Current Loss Characteristic of the Coaxial Cylinder Style Magnetic Coupler

Abstract

This paper analyzed the eddy characteristics of the coaxial cylindrical magnetic coupler by using the finite element method, and simulated the impact of eddy currents on magnetic field. These effects mainly reflected in: weakening the magnetic coupling of the magnetic field intensity, and reducing the magnetic coupling torque. In addition, this paper calculated eddy current power loss, and proposed specific programs to reduce the eddy current power loss.
