Abstract
A motor includes a stationary portion, a rotating portion, and a bearing portion. The rotating portion includes a shaft that rotates about a central axis extending vertically. The stationary portion includes a bearing housing, a stator, and a circuit board. The circuit board is above the stator and includes an insertion hole that permits insertion of the bearing housing. The stator includes a stator core, an insulator, a coil, and a terminal pin. The terminal pin is connected to a conductive wire and connected to the circuit board via a solder portion covered with a coating layer. The insulator includes a base portion and a wall portion. The wall portion protrudes upward from the base portion, is radially outward of the bearing housing, and contacts a radially inner surface of the circuit board at the insertion hole.
