Abstract Based on the design theory of the permanent magnetic adsorption devices,a variable magnetization direction and unit combined device is proposed.This device is composed of closely arranged permanent magnets,whose different magnetizing directions are connected into an annulus.The finite element method is used for parameterized modeling,structural characteristic analysis,magnetic circuit simulation,adsorption force calculation,and structural parameter optimization of the proposed device.The novel and the Halbach type permanent magnetic adsorption devices with the same material and volume are trial-produced.The relation curves between the unit mass adsorption force and the air gap thickness are measured.The experiment results prove that the unit mass adsorption force of the novel device doubles averagely compared with the Halbach device,and the highest amplification is 2.3 times.
