Abstract:
A motor including a rotating portion that rotates about a center axis that extends vertically and a stationary portion that rotatably supports the rotating portion. The stationary portion includes a stator including a coil, radially facing at least a portion of the rotating portion, a base disposed axially below the stator, a circuit board disposed axially between the stator and the base, a conductor electrically connected to the coil and the circuit board, including an extending portion extending axially downward from the circuit board, and a resin portion covering the circuit board and the conductor, connecting the base and the stator. The base is provided in its axially upper surface with an opening that overlaps the conductor when viewed axially.
