To simplify a winding structure of a stator and a rotor of an alternating current electric machine, in a winding a magnetic field formation of a magnetic pole portion is formed with a bobbin structure. In a structural aspect, an eddy current is lessened in an alternating magnetic field. An iron core is formed with a module work and has a reduced metal die cost and it correspond to an alternation in pole number and an iron core having different capacity.
