Abstract

PURPOSE:To obtain a flattened miniature motor fan unit excellent in radiating characteristic, by using a cup-formed coreless motor, and by connecting the side wall of the fan to the side wall of armature so that the outer periphery of the motor may be covered with the fan. CONSTITUTION:For the driving source of a motor fan, a cup-formed coreless motor rotated with a cup-formed coreless armature 13 supported by a shaft 14 between a housing 13 and a field magnet section 1 is used. To the side wall of the coreless armature 13, the side wall of a fan 29 is connected. Then, with a part of the side wall of the fan 29, a part of the outer periphery of the coreless motor is arranged to be covered. By this organization, the weight of the rotational section can be lightened, and the length in the axial direction can be reduced. Besides, the radiating property is improved and noise can be also reduced.
