发明名称 Rotating electrical machine and method of manufacturing the rotating electrical machine
摘要 A method of manufacturing a rotating electrical machine includes: fixing a rotor core to a shaft; assembling a stationary assembly in which a first bearing is fixed to a housing bottom portion of a substantially cylindrical housing member having a closed bottom and in which an annular stator is fixed to an inner circumferential surface of a cylinder portion of the housing member; inserting the rotor core into the stator; fitting an upper portion of the shaft into a second bearing supported by a bearing support member. The method further includes fixing the bearing support member to an upper portion of the housing member; and axially inserting a plurality of rotor magnets into a plurality of axially-extending hole-shaped or groove-shaped magnet holding portions formed in the rotor core, through a magnet insertion hole defined in one of the bearing support member and the housing bottom portion.
