の突極形回転子。[Claim for Utility Model Registration] A thin steel plate for a rotor core is composed of a rectangular plate part which becomes a winding part of a field coil and a split disc part which becomes a magnetic pole part. When the dovetail is fitted into the dovetail groove of the rotating shaft of the rotating electric machine, the rectangular plate portion has different left and right widths divided by the center line in the direction perpendicular to the axis of the rotating shaft. In the disc part, the left and right parts divided by the center line have different maximum widths along the direction perpendicular to the axis, and the width is different from the narrow part of the rectangular plate part divided by the center line. , connected to the narrowest part of the maximum width along the direction perpendicular to the axis in the split disk part,
A rotor core is formed by stacking the rotor core thin steel plates to a predetermined thickness by alternately inverting and overlapping each other, and winding a field coil around the winding portion of the rotor core. By fixing the rotor core to the rotating shaft of the rotating electric machine via the dovetail provided on the rectangular plate part of the thin steel plate for the rotor core, a cooling ventilation passage is created between the rotor core and the field coil. In the salient pole rotor of a rotating electrical machine, the rotor core thin steel plate has a rectangular plate portion having a narrow width divided by the center line;
By making the intersecting angle with the narrowest part of the maximum width along the direction perpendicular to the axis in the split disk part an obtuse angle, the rotor core can be installed vertically with the magnetic pole part facing downward. A salient pole rotor for a rotating electrical machine, characterized in that the back surface of the magnetic pole part of the core is inclined.
