Patent ID: 8294315

Claim:
An inner-rotor brushless motor comprising: a stator core constituted by stator-core blocks connected to each other via thin-walled portions, each stator-core block including a tooth portion around which an energizing coil is wound inside the stator-core block; a rotor disposed inside the stator core and including driving magnets, a rotor yoke that holds the driving magnets, and a shaft coaxially fastened with the rotor yoke; and a holding member configured to hold the stator core, the holding member including, a mounting surface disposed perpendicular to the shaft and brought into contact with a mating member in which the inner-rotor brushless motor is installed; bent portions integrated with the mounting surface, bent upward so as to be substantially perpendicular to the mounting surface, and configured to hold an outer circumferential surface of the stator core; and mounting flanges used for fastening the motor to the mating member, wherein the mounting surface, the bent portions, and the mounting flanges are integrated with each other.
