Claims

[Scope of Claim for Utility Model Registration] 1. Connecting pieces between poles pulled out from the field coils of adjacent salient magnetic poles are stacked one on top of the other and are tightened with a retaining bolt and a retaining nut, and the retaining bolt and retaining nut are tightened. Two nuts are screwed together via an insulating collar to the upper male threaded part of the support stud that penetrates through the insulating tube, and the above-mentioned vertically stacked inter-electrode connecting pieces are sandwiched between these two nuts. In a structure in which the pole-to-pole connection portion of a salient field pole is supported by tightening from the top and bottom and fixing the lower part of the support stud to the rotor yoke, a locking nut is screwed in advance to the lower male threaded portion of the support stud. Then, a dovetail key is screwed into the male threaded part protruding from this locking nut, and the locking nut is tightened and fixed, and a compressible helical spring is fitted into the fixing pin implanted at two locations in the axial direction of the rotor yoke. An inter-pole connection support structure for salient field poles, characterized in that the dovetail key is inserted through through holes provided at two locations in the longitudinal direction. 2 Attach a flange whose upper and lower surfaces are spherical to the lower end of the support stud, provide a spherical pedestal that movably abuts the lower spherical surface of this flange, and fix this spherical pedestal to the upper surface of the rotor yoke with screws. 2. The spacing between salient field poles according to claim 1, further comprising a retaining ring movably covering the upper spherical surface of the flange, and the retaining ring being screwed and fixed to the upper surface of the rotor yoke. Connection support structure. 3. A salient pole according to claim 1, characterized in that a spherical support is provided at the lower end of the support stud, and a presser ring movably covering the spherical support is fixed to the upper surface of the rotor yoke by screwing. Pole-to-pole connection support structure for shaped field poles.
