Abstract
A rotor for a dynamo-electric machine is capable of reducing the leakage of magnetic flux between triangular magnetic poles, making it possible to protect magnets disposed between the triangular magnetic poles from damage. The rotor is equipped with: a rotor coil through which current flows to generate magnetic flux; a field core which is provided such that it covers the rotor coil and which is composed of a first field core member and a second field core member having a triangular magnetic poles, respectively; a plurality of magnets which are disposed between adjacent triangular magnetic poles and which have been magnetized in a direction so as to reduce the leakage of the magnetic flux between the triangular magnetic poles. Each magnet is constituted by a first magnet section secured by a securing means to the triangular magnetic pole of the first field core member and a second magnet section secured by a securing means to the triangular magnetic pole of the second field core member.
