Description

[Brief explanation of the drawing]

FIG. 1 is a partial sectional view showing a conventional device, FIG. 2 is a partial sectional view showing an embodiment of this invention, and FIG. 3 is a sectional view showing the hollow shaft used in FIG. In the figure, 1 is an armature rotating shaft, 2 is an armature core, 3 is an armature winding, 4 is a stator, 7a is a fitting part, and 7b is a loose fitting part. In each figure, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] A sliding contact made of a rotor core fixed to a rotating shaft and wound with a rotor winding, and a conductive material connected to the rotor i-wire at a position separated from the rotor core by a required distance in the axial direction. and an annular sliding body fixed on the rotating shaft in parallel with the rotor core, the sliding body having a mechanical connection portion with the rotor winding. A rotating electric machine, characterized in that a protrusion protrudes toward the rotor core side in the axial direction, and the sliding contact body is locked against relative rotation with respect to the rotating shaft only at the protrusion. rotor.
