ABSTRACT:
The rotational electric machine includes a cylindrical yoke and a field winding connected to an inner surface of the cylindrical yoke. The field winding is composed of plural formed coils, each coupled to a bobbin. The bobbin includes a first flange for insulating the formed coil from the inner surface of the cylindrical yoke, a second flange for insulating the formed coil from a supporting brim of a pole core and a pipe portion for insulating the formed coil from a boss portion of the pole core. The first flange is made all around the pipe portion while the second flange is formed to extend only in the lateral direction of the pipe portion. The bobbin is easily coupled to the formed coil by flexibly bending the bobbin. Alternatively, the bobbin or bobbins may be made by folding a bobbin sheet after placing the formed coils on the bobbin sheet.
