PROBLEM TO BE SOLVED: To provide a stator core, a stator and a motor, capable of eliminating waste of a stator core material.SOLUTION: In a stator core 40 of a single stator S1, a belt-shaped plate 60 made of belt-shaped electromagnetic steel sheet is used and punched in the longitudinal direction thereof to obtain first and second punched pieces 63, 64, and the first and second punched pieces 63, 64 are bent to mold claw-shaped magnetic poles 43, 44 of first and second stator sides. Then, both ends in the longitudinal direction of the belt-shaped plate 60 molded to have claw-shaped magnetic poles 43, 44 of the first and second sides are connected to each other by welding.SELECTED DRAWING: Figure 5 |
