ROTOR, ROTATING ELECTRICAL MACHINE USING SAME, AND POWER GENERATOR

摘要

Disclosed are a rotor that uses relatively few magnets and realizes a rotating electrical machine with excellent efficiency, and a rotating electrical machine using the same. The rotor comprises a cylindrical laminated core that is formed by stacking magnetic steel sheets and magnets (26) that are disposed in the interior of the laminated core, wherein the laminated surface of the laminated core is provided with elongated first holes (20a) and second holes (20b), which form L-shaped holes (23) that are disposed in an L-shape with the tips (23a) thereof facing the center of rotation (20e) side. The L-shaped holes (23) are arranged in a plurality in the circumferential direction at a prescribed pitch, the lengthwise dimensions (La) of the first holes (20a) are formed larger than the lengthwise dimensions (Lb) of the second holes (20b), the magnets (26) are inserted into the first holes (20a), nonmagnetic conductors (27) are inserted into the second holes (20b), nonmagnetic conductors (28) are also inserted into third holes (20c), and end rings (29), which cover the laminated core, are mounted on both ends in the direction of stacking of the laminated core.
