PURPOSE:To effectively utilize the core material for the titled stator by a method wherein the groove area of both coil inserting groove at the smallest pitch of the main and the auxiliary coils and the coil inserting groove for the auxiliary coil of the second row from the bottom is made smaller, and the width of a yoke is made larger. CONSTITUTION:A yoke section 82 of wide width is arranged in the intermediate part of a magnetic pole using the main coil 6, a yoke section 81 of narrow width is arranged in the intermediate part of the magnetic pole using the auxiliary coil 7, and the cutting width B of the core material is reduced. Also, the groove area is reduced by arranging the coil of small quantity and small pitch, the required yoke width is maintained, and the cutting width B of the core material is reduced, thereby enabling to contrive effective utilization of the core material. |
