摘要： A method of manufacturing a bearing mechanism of a motor includes steps a)-e). In step a), a bearing assembly is assembled. In step b), an upper seal gap between an upper thrust portion and an upper hub annular portion is arranged to face downward to increase the width of a gap between an outer tubular portion and a flange portion, or a lower seal gap between the outer tubular portion and a lower hub annular portion is arranged to face downward to increase the width of a gap between the upper thrust portion and the flange portion. In step c), pressure in all gaps is reduced. In step d), lubricating oil is injected into the upper or lower seal gap which faces upward, and a predetermined time or longer is allowed to pass. In step e), pressure is returned to atmospheric pressure.

摘要： A spindle motor according to an embodiment of the invention includes a rotor hub formed of a ferromagnetic material and a rotor magnet held by the rotor hub. The rotor hub has a flange having a shield surface that faces an upper end surface of the rotor magnet via a clearance in the axial direction and formed of a ferromagnetic material. On the outside in the radial direction of an outer peripheral surface of the rotor magnet in the flange, a rim projected downward from the shield surface of the flange is formed.

摘要： A spindle motor includes a base portion, a rotor hub, a stator, and a circuit board. The base portion preferably includes a through hole and is arranged to spread out radially around a central axis. The rotor hub is arranged above the base portion to rotate about the central axis. The stator is arranged above the base portion, and includes coils each including at least one lead wire. The circuit board is arranged radially outward of the through hole, and arranged on a lower surface of the base portion. The base portion includes a communicating groove arranged to join the through hole and the circuit board to each other. The at least one lead wire of the coils is arranged to pass inside the through hole and the communicating groove to be electrically connected to the circuit board. The through hole is sealed with a sealant.

摘要： In a motor, an annular radially extending gap is defined between an outer annular surface and a lower surface of an annular cover portion. The radially extending gap has an axial width smaller than a maximum width of an upper seal portion defined between an outer circumferential surface of an upper thrust portion and an inner circumferential surface of a tubular portion. An annular axially extending gap is defined between an inner cylindrical surface and a radially inner edge of the annular cover portion. The axially extending gap has a radial width smaller than the maximum width of the upper seal portion.
