[Brief explanation of the drawing]

Figure 1 is a front view of a salient pole type rotating field core with a conventional structure;
The figure is a front view showing only the magnetic pole core, Figure 3 is an axial sectional view showing the field core assembled into the shaft, Figure 4 is a perspective view of the magnetic pole mount, and Figure 5 is a conventional FIG. 6 is a perspective view of an improved field core; FIG. 6 is an axial cross-sectional view showing the field core of FIG. 5 assembled into a shaft; FIG. 7 is a field core according to an embodiment of the present invention. A perspective view, FIG. 8 is an axial sectional view showing the field core in FIG. 7 assembled into the shaft, and FIG. 9 is an IX in FIG. 8.
This is a cross section (2) taken along the -IX line.

Claims (1)

[Scope of utility model registration request] In a rotor core of a salient pole type rotating field type rotating electric machine, the rotor core is integrally molded into a predetermined shape from a thick steel plate material, and the required number of pieces are laminated on the rotor shaft, and the area around the shaft hole of the above-mentioned thick steel core plate is A field core for a rotating electric machine, characterized in that a cooling ventilation passage is provided, and the core plate is mounted on a rotating shaft with a space between the core plates rather than in close contact with the rotating shaft.
