摘要： A motor includes a rotating body including a magnet, and a fixed body including a stator. The stator includes a stator core having an annular core back portion with an upper and a lower surface, and a plurality of circumferentially spaced-apart tooth portions extending from the core back portion in a direction away from the rotational axis, and a plurality of coils provided by winding a conductive wire around the tooth portions of the stator core with multiple turns. The rotor holder is arranged axially above the stator to cover the stator. Further, an annular or arc-shaped attracting magnet arranged to attract the rotor holder toward the stator is arranged radially inwardly of the core back portion, the attracting magnet having an upper surface axially facing toward the rotor holder, and a lower surface arranged axially below the upper surface of the core back portion of the stator core.

摘要： A brushless motor includes a substantially flat attachment plate and a circuit board. The attachment plate includes a plurality of motor attachment portions and a base portion arranged to interconnect the motor attachment portions. The circuit board is arranged on an upper surface of the base portion and includes a first area to which electronic parts are attached. The upper surfaces of the motor attachment portions are arranged higher than the upper surface of the base portion. The height of the upper surface of the circuit board in the first area is substantially equal to or greater than the height of the upper surfaces of the motor attachment portions.

摘要： A motor is provided with a chucking device enabling attachment and detachment of a disk-shaped storage medium. In the motor, a turntable forming a portion of the chucking device is disposed axially above a rotor holder. The turntable has a placement portion on which the storage medium is placed. An inner recess is formed on an outer surface of a shaft between a position at which the rotor holder is fitted and another position at which the turntable is fitted. An outer recess is formed to radially face the inner recess and is concave away from a center axis. Adhesive is placed in the inner recess and the outer recess.

摘要： There is provided a motor for a disk drive apparatus. The motor includes a cone member, a substantially annular back yoke, a substantially annular clamp magnet, an adhesive agent, and a motor unit. A storage portion includes a clamper insertion portion formed in a position axially overlapping with the clamp magnet to accommodate the clamper when the clamper comes closer to the cone member. The back yoke includes a first surface opposed to the clamp magnet in a contact or adjoining relationship therewith and a second surface positioned near the clamper insertion portion and kept spaced apart from the clamp magnet. The cone member includes an adhesive agent staying portion arranged to accommodate a part of the adhesive agent. The adhesive agent stays portion being defined between the imaginary surface extending axially downwards from the circumferential surface of the clamp magnet facing the clamper insertion portion.

摘要： A data storage medium support member is produced by resin molding. The data storage medium support member includes an accommodating portion, a guide portion, and a gate cut portion. The accommodating portion accommodates a magnetic member around a central axis. The guide portion has a guide surface for guiding an inner edge of a disc, and is arranged radially outward of the accommodating portion. The gate cut portion is formed on a rear surface of the guide portion. The data storage medium support member can be produced by the resin molding while securing space for accommodating the magnetic member and preventing an increase in the axial dimension of the data storage medium support member.
