PURPOSE:To maintain the thickness of a stator core at constant value by opposing the sheared part f the wall surface of a core slot to two cores formed by laminating cores formed with prescribed clamping hole and erected projection by half of the prescribed thickness and then clamping them. CONSTITUTION:One core 11' is inverted and clamped so that 1/2 cores 11, 11' laminated in substantially 1/2 of the prescribed thickness are opposed at the sheared part 7 projected at the end produced when the wall surface 6 of the core slot part is punched. The first erected projections 12, 12' and the first clamping holes 13, 13' of the size engaged with the projections 12, 12' are formed at the positions symmetrical to the center at the core piece forming the cores 11, 11', the second clamping holes 14, 14' of the same size as the holes 13, 13' are formed at the outside of the projections 12, 12', and the second erected projections 15, 15' projected in the same direction as the projections 12, 12' symmetrical to the holes 14, 14' to the center is formed at the outside of the holes 13, 13'. |
