A plurality of coils of the stator include three coil groups including one or more of the coils defined by a single conducting wire. A joint portion where at least two of three common wires are joined together to define a single common wire is provided on the upper side of the base portion. Each common wire is one end portion of the conducting wire defining a separate one of the three coil groups. Each of the common wire elements and lead wire elements passes through a separate one of the base through holes. Each base through hole includes a circular sealing portion between an inner circumference and an entire circumferential extent of a corresponding one of the wire elements.

摘要： A motor includes a bearing mechanism including a shaft disposed along a center axis extending in a lengthwise direction, a sealing member disposed on a lower side of the bearing mechanism, a stationary portion including a base constituting a part of the housing, and a rotary portion rotating relative to the stationary portion about the center axis via the bearing mechanism. The base has a through hole defined therein so as to have a center aligned with the center axis and pass through the base in an axial direction. The bearing mechanism is fixed to the base in a first fixing region defined between an inner circumferential portion of the base and an outer circumferential portion of the bearing mechanism. The sealing member is fixed to the base in a second fixing region defined between the inner circumferential portion of the base and an outer circumferential portion of the sealing member. At least one of the first fixing region and the second fixing region includes a sealing region.

摘要： A spindle motor includes a base portion and a bearing mechanism. A fixing region, which includes a first region at which the base portion and the bearing mechanism are fixed to each other and a second region at which a seal gap is defined between the base portion and the bearing mechanism, is located between an inner circumferential portion of the base portion which defines a through hole and an outer circumferential portion of the bearing mechanism. The inner circumferential portion of the base portion has, at least in the second region, a degree of surface roughness greater than a degree of surface roughness of the outer circumferential portion of the bearing mechanism. The seal gap gradually decreases in radial width with increasing height, and includes an adhesive along an entire circumference of the seal gap.

摘要： A lead wire guide member is made of an electrically insulating material, and arranged to extend along a lower surface of a base portion. A movement restricting portion is arranged in the lower surface of the base portion. Lead wires are arranged to pass through base through holes to reach the lower surface, and extend along the lower surface to be connected to the circuit board. A spindle motor further includes a sealant arranged between an entire circumferential extent of each base through hole and an entire circumferential extent of the corresponding lead wire. The lead wire guide member includes an inner edge and an outer edge. The inner edge is arranged opposite to the lead wires. The outer edge is arranged to at least face radially outward. The movement restricting portion is in contact with the outer edge of the lead wire guide member.
