定されるようになっている。In the conventional device having such a configuration, the clamper (3) is applied to both sides of the plate surface of the laminated steel plate in which a required number of steel plates are stacked, and the rivet (4) is passed through the rivet hole provided at the corresponding position and the stator core (1) and the clamper (1). (3) and (3) are fixed together by crimping and laminated. Next, in order to make the magnetic pole surface above the stator core (1) and the mounting surface of the clamper (3) parallel to each other, the back side of the clamper (3) is machined to be machined. After that, winding work of the stator winding is performed using the slot (2), and the stator core (1) is fixed by fixing the back side of the clamper (3) to a base or a housing with the fixing hole (5). It has become so.

としての機能に悪影響を与える恐れもある。However, in such a conventional apparatus, the back surface of the clamper (3) is machined after the stator cores (1) are stacked as described above. The reason is that the gap between the rivet hole and the rivet (4) causes the stator core (1) and the clamper (3) to shift from each other. For this reason, the above-mentioned machining after assembly is troublesome, and the number of man-hours is increased accordingly. In addition, if the deviation when fixed is significant, it may be necessary to rework the fixing hole (5). Further, if the caulking is loosened for some reason, the pressure-welded steel plates are misaligned with each other, and the magnetic pole surfaces are not aligned, which may cause leakage of magnetic flux and adversely affect the function of the linear motor.
