As shown in FIGS. 1 and 2, conventional stator winding frames have been resin-molded with a U-shaped cross section and fitted into cores 3 to form winding frames 4. However, the second
As can be seen in the figure, of the magnetic flux of the magnet 2, only φ 1 passes through the core 3, and the magnetic flux φ 2 that comes out of the part of the magnet 2 that is away from the core 3 becomes leakage magnetic flux.
There was a large amount of magnetic flux that was not effectively linked to the winding 5, resulting in poor efficiency. Therefore, in order to improve efficiency,
Conventionally, an improvement has been made in which the plates at both ends of the core 3 are bent to provide a portion 3a facing the magnet 2, as shown in FIG. 3, and φ 2 ' is utilized as an effective magnetic flux. However, even in this case, in order to provide the bent portion 3a, the core 3
The number of types of laminated iron plates constituting the structure has increased to three, and the bent portion 3a has a complicated shape, resulting in an increase in cost.

In order to solve the above-mentioned drawbacks, the present invention makes the winding frame made of molded resin containing magnetic powder, and extends it in the radial direction in order to reduce the gap with the magnet facing surface, so that it is approximately the same as the outer diameter surface of the magnetic pole piece of the core. The purpose is to make it possible to use magnetic flux effectively with a simple and inexpensive configuration by making it with a diameter.

The present invention will be described below with reference to embodiments shown in the drawings. In Fig. 4, 1 is a bowl-shaped rotor made by pressing iron plates, 2 is an arc-shaped magnet magnetized in the radial direction and fixed to the inner peripheral surface of the rotor 1, and 3 is made by laminating iron plates. The star-shaped core 4' is a winding frame integrally formed by resin molding on the outer periphery of the salient pole winding part of the core 3, and the molded resin is filled with insulating magnetic powder such as ferrite. In its formed state, it is an insulating soft magnetic material. 4a' is the outer diameter surface of the winding frame 4' facing the magnetic pole of the magnet 2;
As shown in the figure, the outer diameter surface 3a of the magnetic pole piece of the core 3 (first
It has an arc shape with approximately the same diameter as the one shown in Figure). 5 is a winding wound around a winding frame. φ 1 directly to core 3,
The incoming magnetic flux φ' 2 is the magnetic flux that enters the core 3 through the winding frame 4a'.

As a result, the magnetic flux φ' 2 , which conventionally was used as leakage magnetic flux, can be used as effective magnetic flux, and the output can be increased with a simple and inexpensive configuration.

Although an example has been shown in which the winding frames 4' attached to each salient pole are connected to each other and integrally molded on the outer periphery of the core 3, the winding frame 4' is divided into two in the axial direction and It may be fixed by fitting. Alternatively, the winding frame 4' may be separately fixed for each salient pole.
Furthermore, the present invention can also be applied to an I-shaped core or a stator of an internally rotating magnet generator.

As described above, in the present invention, the winding frame is molded with molding resin filled with insulating soft magnetic powder, and the outer diameter surface of the winding frame facing the rotor magnetic poles is placed outside the magnetic pole pieces of the core. Since it is made into an arc shape with almost the same diameter as the radial surface, the winding frame can be effectively used as a magnetic path.
With a simple and inexpensive configuration, it has the excellent effect of effectively linking the magnetic flux from the rotor to the windings and increasing the output.
