Being the core plate which forms the rotor core by the fact that it is driven out

摘要

PROBLEM TO BE SOLVED: To easily and definitely identify presence/absence of rotation lamination when a core plate is laminated, without changing a mass center position of a rotor, in the core plate for the rotor for a rotating electric machine.;SOLUTION: In a core plate 10, an identification shape part 30 is installed in one of a plurality of window parts 24, and an adjustment shape part 40 is installed in the other one. The identification shape part 30 is a recessed part formed by partially notching the shape on the inner diameter side of the window part 24, and the adjustment shape part 40 comprises two recessed parts 41, 43 formed by partially notching the shape on the inner diameter side of the window part 24. The identification shape part 30 and the adjustment shape part 40 are arranged symmetrically with respect to an axis passing through a center point 12. The mass of the notch recessed part of the adjustment shape part 40 is set to be the same as that of the notch recessed part of the identification shape part 30.;COPYRIGHT: (C)2012,JPO&INPIT
