PROBLEM TO BE SOLVED: To solve the problem of deterioration of wiring quality caused by the interference of a yoke with the series coil winding work when dividing the stator core into four sections with the yoke. SOLUTION: The stator core is divided into eight sections consisting of four sections of divided cores a2, in which a tooth 5 and the yoke are integrated before coil winding, and four sections of divided cores b3 of the yoke part 10 clamped against the divided core body a2, and is integrated into a combined annular body. These eight sections are assembled in a ring after coil winding.
