Abstract
A magnetic pole for facing an air gap with a stator is formed with a parallel quadrilateral shape or a quadrilateral shape having a skew effect and is obtained by a single iron core or plural iron cores. To make simply a winding structure of a stator and a rotor of an alternating current rotary electric machine, by a bobbin structure a magnetic field formation of a magnetic pole portion is formed. A magnetic pole structure having a projection portion is provided to form an overlap structure with another phase magnetic pole. An electromagnetic combination of each phase is strengthened and each phase magnetic poles is carried out a systematic separation, dispersion, and an arrangement.
