Abstract

This motor includes a base and a circuit board arranged on a lower surface of the base. The base includes a first annular portion and a second annular portion. The first annular portion is arranged under a stator. The second annular portion is arranged under a flange portion of a hub. A conducting wire drawn out from the stator is arranged to pass through a through hole defined in the first annular portion, and is soldered to a land portion of the circuit board. The second annular portion is arranged to have an axial thickness smaller than that of the first annular portion. The land portion is arranged radially inward of the through hole. The above arrangement makes it easier to achieve a reduced axial dimension of the motor while ensuring a sufficient axial dimension of the hub, which is arranged axially above the second annular portion.
