  • Laminated stator core
    Patent number: 8456057
    Abstract: A laminated stator core 10, formed by laminating stator core sheets 17, each of the stator core sheets 17 punched out from a magnetic metal sheet 32 so as to have a common axis with a rotor core sheet 36 which punched out from the magnetic metal sheet 32 before the stator core sheet 17 is punched out; the stator core sheet 17 including a thin section 24 in a magnetic pole shaft piece 20; the thin section 24 formed by pressing a part or a whole of a magnetic pole shaft piece 20 in a thickness direction, and elongating the same in a radially inward direction; and further the thin section 24 having a thickness within 50-95% of that of the magnetic metal sheet 32 and a radial length within 30-100% of that of the magnetic pole shaft piece 20. This enables a magnetic pole piece 19 to be elongated to form the thin section 24 without adverse effect on magnetic characteristics thereof, and improves caulking accuracy and dimensional accuracy for blanking both of the core sheets 17, 36 from one magnetic metal sheet 32.
