Abstract:
A motor includes a rotor rotatable about a center axis extending vertically, a stator radially opposing the rotor, a bracket holding the stator, a circuit board including an upper surface with a first wiring pattern and a lower surface with a second wiring pattern, and a first fixing portion having conductivity and fixing the circuit board to the stator. The stator includes a stator core having conductivity. The first fixing portion includes a board holding portion holding the circuit board, and a stator fixed portion fixed to a portion of the stator core. The board holding portion is in contact with the first wiring pattern and the second wiring pattern.
