摘要： A stator core having twelve stator poles, coils wound around the stator poles, and a hybrid type rotor are included. The stator poles inwardly and radially extended from an annular yoke portion. Each of the respective stator poles has the same number of inductors. The coils are connected so that a pair of the stator poles being substantially symmetric with respect to a point are excited in opposite polarities. The rotor is arranged with a predetermined air gap with respect to the inductors, the rotor has a pair of rotor cores each of which has rotor teeth facing to the inductors and a permanent magnet magnetized in the axial direction sandwiched therebetween. The angles between inductors at the corresponding positions of adjacent stator poles are defined by repeating three sets of angular distributions each of which includes three times of 29.1 degrees and one time of 32.7 degrees when a number of rotor teeth equals 100.
