Stator core and method of manufacturing same |
摘要 |
A stator core 10 and its manufacturing method, the stator core 10 including laminated stator core sheets 17, each of the stator core sheets 17 punched out from a magnetic metal sheet 32, a central portion of the magnetic metal sheet 32 previously punched out to form a rotor core sheet 36, the stator core 10 including a thin section 24 formed in a magnetic pole piece 19 of each of the stator core sheets 17, the thin section 24 formed by pressing both sides of the magnetic pole piece 19 in a thickness direction and radially-inwardly elongating the magnetic pole piece 19. The present invention prevents the magnetic pole piece 19 from being curved and improves interlocking accuracies and dimensional accuracies in blanking the rotor core sheet 36 and the start core sheet 17 from one magnetic metal sheet 32.
