FE analysis of electromagnetic circuit of a written pole motor

The structure and working principle of a written pole motor are presented. To the analysis of the motor, a field-circuit model of electromagnetic phenomena that takes into account magnetic hysteresis of magnetically hard materials is applied. The motion of the rotor, non-linear properties of magnetically soft materials, and eddy currents induced in the conductive massive materials are taken into account. To solve the equations of the proposed model, the finite edge element method and step-by-step algorithm are used. The elaborated method and software are applied to the analysis of the written pole motor
