STACKED STATOR CORE, AND ITS MANUFACTURING METHOD AND ITS MANUFACTURING DEVICE

PROBLEM TO BE SOLVED: To provide a stacked stator core that gives the magnetic flux passing through the iron core of magnetic poles to a rotor more equally, and that enables winding to be conducted stably, and to provide its manufacturing method and its manufacturing device. SOLUTION: The stacked stator core 10 is structured, by combining stacked and divided iron cores 13 that are divided by each magnetic pole iron core 12, each being provided with a wide magnetic pole 14 formed at the inside end. First and second connectors 15, 16 formed at both sides of the divided yoke of each stacked and divided iron core 13 are straight in the direction of stacking, and the magnetic pole iron core 12 of each stacked and divided iron core 13 is provided at a constant skew angle in the stacking direction. In its manufacturing method, a slot-blanking mold that forms both sides of magnetic pole pieces 22 of the divided iron core pieces 19 is rotated at a predetermined pitch for each divided iron core piece 19.
