摘要： A motor includes a bearing mechanism, a stationary unit including a stator arranged radially outwards of the bearing mechanism, and a rotary unit supported by the bearing mechanism at the upper side of the stationary unit for rotation about a center axis with respect to the stationary unit. The rotary unit includes a substantially cylindrical closed-top rotor yoke having a cover portion arranged to cover the stator. The bearing mechanism includes a substantially cylindrical closed-bottom bush formed by a press work, a sleeve fixed inside the bush and provided with an upper portion protruding beyond the bush and a shaft inserted into the sleeve. An upper end of the bush is lower than or flush with an upper end of the stator in a direction parallel to the center axis.

摘要： In a motor, a retaining claw with a slanted surface is arranged around the upper end of a tubular portion of a housing for mounting a rotor. A cylindrical portion is integrally formed in a peripheral area of a rotational axis of a turntable. A retaining member with retaining portions having a J-shaped cross section is attached to the lower surface of the turntable. Arms of the retaining portions are located in the vicinity of the lower end of the cylindrical portion. In mounting the rotor onto the housing, the retaining portions contact the slanted surface and the arms are elastically deformed. Upon completion of the mounting, the arms return to a state before the elastic deformation, so that the retaining claw prevents the rotor from coming off.

摘要： An inner rotor type motor includes a turn table having a disk loading portion and a central opening portion arranged to allow a disk to be attached thereto and removed therefrom, a rotor concentric with a rotation axis of the turn table, the rotor including a rotor holder having therein a rotor magnet and a cylindrical portion arranged to retain on an outer circumferential surface thereof the rotor magnet, and a stator having an armature arranged to oppose an outer circumferential surface of the rotor magnet via a gap therebetween. The turn table is affixed in an axial direction on an upper portion of the rotor holder, and the disk loading portion is arranged radially outside the cylindrical portion of the rotor holder. A disk loading surface of the disk loading portion is arranged to make contact with the disk, and a bottom portion of the disk loading portion is arranged axially below an area where the turn table and the rotor holder make contact with one another. The disk loading portion has a predetermined thickness in the axial direction, thereby preventing a deformation of the disk loading portion even when the disk is placed thereupon.

摘要： A motor includes a circuit board having a bottom facing surface and a plurality of connecting land portions provided thereon. The circuit board includes a through hole for allowing a wire to extend therethrough. An attachment board makes contact with the bottom facing surface of the circuit board. The attachment board includes an opening portion penetrating the attachment board. The wire is wound around a stator core arranged above or equal to the circuit board in an axial direction so as to form a coil. The wire extending from the stator core is soldered to the connecting land portion. The opening portion of the attachment board is arranged at a position such that it makes no direct contact with the wire.
