Patent ID: 8089184

Claim:
A motor comprising: a rotor unit rotatable about a center axis and including a rotor magnet; a stator unit including: a stator core including a core back and a plurality of teeth radially outwardly extending from the core back, a radially outside surface of each of the teeth radially faces the rotor magnet; a first insulator arranged at a first axial side of the stator core; a second insulator arranged at a second axial side of the stator core, the second insulator includes a projection axially extending and arranged between circumferentially neighboring teeth and including a hole substantially axially extending therein from a first axial side end of the projection; a conductor pin inserted into the hole of the projection, a first axial side end of the conductive pin is arranged in the hole and a second axial side end of the conductor pin protrudes toward the second axial side from the projection; a coil defined a wire wound around each of the teeth via the first insulator and the second insulator and electrically connected to the conductor pin; a notched portion in which the second axial side end of the conductor pin is inserted; a circuit board arranged in the second axial side of the stator core via the second insulator, to which the other side end of the conductor pin is electrically connected; and a base arranged to support the stator unit thereon; wherein the projection is arranged axially lower than an axially middle portion of the stator core; the wire is arranged to be entwined around a portion of the conductor pin that includes a solder material electrically connecting the wire and the conductor pin, the portion of the conductor pin includes a width that is smaller than a width of the notched portion; and the second insulator includes a convex portion axially extending to the second axial side at a position radially inside of the conductor pin; and the base includes a concave portion in which the convex portion of the second insulator is fitted such that the stator unit is positioned on the base in the circumferential direction.
