초록

This paper introduces the improved analysis method for PMDC (Permanent Magnet DC) motors. The effect of field yoke is considered by equivalent area. Overhang effect, caused by different axial length of magnet and armature, is analyzed by 3D EMCN(Equivalent Magnet Circuit Network) method. Then brush contact resistance and mechanical loss extracted by experimental data are used in characteristic analysis. The validity of the proposed method is verified by the comparison of analysis results and experimental ones.
