This paper describes some characteristics of a compound magnetomotive forces (CMMF) motor employing a dual winding (DW) method. The CMMF motor can utilize three kinds of characteristics because of a special magnet arrangement. A 4-12 pole CMMF motor with changeable electric and magnetic characteristics had already been proposed in the previous study. The CMMF motor, however, has a problem in its driving range because of voltage interference. In this study, the DW method is proposed to solve this problem by utilizing magnet pole combinations and the winding distribution. This paper shows that the proposed motor can achieve multiple high-efficiency points by utilizing the parameter distribution for two kinds of magnet characteristics.
