Patent ID: 7876008

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 an axially one side of the stator core, a second insulator arranged at an axially other 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 an axially other side end of the projection, a conductor pin inserted into the hole of the projection, an axially one side end of the conductive pin is arranged in the hole and an axially other side end of the conductor pin protrudes into the axially other side from the projection, a coil defined by winding a wire around each of the teeth via the first insulator and the second insulator and is electrically connected to the conductor pin, a notched portion in which the axially other side end of the conductor pin is inserted, and a circuit board arranged in the axially other 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 point of the stator core, the wire is 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, the second insulator includes a convex portion axially extending to the axially other side at a position radially inside of the conductor pin, the convex portion radially faces 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.
