摘要： In a stator for an electric motor, insulating members are formed on laminated iron cores divided for each pole-tooth unit in the direction of the output shaft and windings are applied perpendicularly to the pole-tooth portions in a high-density alignment. After a predetermined number of the laminated iron cores are combined so as to form a cylindrical configuration, they are welded at the outer end portions of the dividing surfaces in the direction of lamination so as to construct an integral structure stator with rigidity, thereby enabling high densification of the windings (conductor space factor of 70%) and space-savings in the winding end portions. Further, as any joint portions between the pole-tooth portions are not necessary, reduction (5 to 10%) in motor efficiency due to such joint portions can be prevented, and, as any integrally forming by resinous members is not necessary, inter-winding short-circuiting is not caused. Welding may be replaced by adhesive bonding. Otherwise, an annular member may be employed to form an integral structure of the divided iron core lamination.
