Abstract

A motor includes a shaft with a central axis along an up and down direction as a center, a cylindrical rotor main body fixed to the shaft, a rotor fan fixed to the shaft at an upper side of the rotor main body, an armature facing the rotor main body in a radial direction, a bus bar electrically connecting the armature to an external power supply, a bus bar holding portion that holds the bus bar, and a housing that accommodates the rotor main body, the rotor fan, the armature, the bus bar, and the bus bar holding portion therein. The housing includes a first opening positioned above the armature and a second opening below the armature in the up and down direction. The bus bar holding portion is disposed outward the rotor fan in the radial direction.
