Abstract

In this paper, we propose an analytical method for a motor with skewed magnets.<br>In our proposal method, a motor is divided into the some segments, and then the sum of the induced voltage of each segments are coupled with the circuit equation, so that it becomes possible for 2-D FEM to take skewed effects into account.<br>The proposed method has been applied to the analysis of DC Blushless Motor. Calculated results of induced voltage waveforms on no-load show close agreement with measured values. In addition the results of winding current waveformes and average torque vs. speed characteristics in steady state indicate good results. These results confirmed the validity of this method.
