Abstract

In this paper, at first, the cage conductor effects on magnetization of rotor magnet in a written pole motor (WPM) are investigated. To this aim, the residual flux density of rotor magnet after exciter operation is analyzed with FEM considering magnetization characteristics of a hard magnetic material and eddy currents of rotor bars. Then, through the FE-analysis with variance of the number and shape of rotor bars, the cage rotor to maximize the magnetization is determined.
