。[Example] Hereinafter, an example of the present invention will be described with reference to FIG. A laminated iron core 2 is fixed to a shaft 1, slots 3 are arranged at equal intervals on the outer periphery of the iron core 2, and a coil 4 is embedded inside. A groove 6 is formed in the opening of the slot 3 on the outer periphery of the iron core 2, and the thin plate-shaped magnetic member 5 is pressed from the outer periphery, and both sides are engaged with the groove 6, so that the magnetic member 5 itself and the coil 4 are Preserves scattering due to centrifugal force. Magnetic member 5
It is preferable to use elastic spring steel or the like, and an insulating layer 7 may be formed on the coil 4 side to prevent the coating of the coil 4 from peeling off when pressed. Fig. 2 is a partial perspective view of Fig. 1 and shows the case where varnish 9 is applied to the coil end 8.
The varnish 9 from the coil end 8 is impregnated from both ends of the iron core 2 toward the center, filling the gap between the coil 4 and the iron core 2. It also adheres to the coil 4 side of the magnetic member 5, and the magnetic member 5 is also fixed. FIG. 3 is a cross-sectional view taken along the line A-A in FIG.
FIG. 4 shows a case in which it is divided into two parts in the axial direction, and the magnetic member 5 is omitted in the central part. Dividing in this way reduces the pressing force and makes the work easier. FIG. 5 shows other embodiments of the magnetic member 5, in which (a) a hole 5a is provided to reduce the weight, and (b) the iron core 2 is partially joined, and both sides of the magnetic member 5 are optionally connected. The convex portion 5b is formed to reduce the pressing force and facilitate the work.
