Abstract
A motor includes a stationary portion and a rotary portion. The stationary portion includes an armature, a circuit board below the armature, and a base portion. The base portion includes a bearing holder and a radial gap is defined between the circuit board and a wall portion. The circuit board includes a through-hole passing through the circuit board, and at least one exhaust hole passing through the circuit board in an axial direction. A filler material is on upper and lower sides of the circuit board. The radial gap, a first exhaust hole extending in a radial direction, and a second exhaust hole extending in a circumferential direction from the first exhaust hole communicate with each other through an axial space between a lower surface and an upper surface of the base portion.
