A motor includes a stator, a rotor rotatable relative to the stator, a circuit board fixed to the stator, and a heat sink disposed on the circuit board, a side surface of the circuit board facing the heat sink has an insulating region and a metal heat dissipation region without solder mask. The thermal resistance between the circuit board and the heat sink can be reduced by the metal heat dissipation region, thereby improving the heat dissipation of the circuit board.
