Abstract:
An electric rotating machine having a rotor rotatably disposed in an inner radius side of a stator through a gap, said rotor comprising rotor windings contained in a plurality of slots formed in a rotor core; an insulation block placed between a wedge arranged at a peripheral side of said rotor core outward of at least one of said rotor windings of a corresponding one of said slots and said at least one of said rotor windings;wherein said insulation block is an insulation which is formed by one of filling and mixing at least one of granular and short-fiber insulating materials having a thermal conductivity higher than 5 W/mÂ·K in a resin, and which has a thermal conductivity in a thickness direction higher than 0.35 W/mÂ·K.
