Abstract: The present invention provides a motor structure including a heat dissipation module, a motor base, a circuit board, a rotor and a winding set. The heat dissipation module has a first side and a second side opposite to each other. The motor base is connected to the heat dissipation module. The first side and the second side are uncovered. The thermal conductivity of the heat dissipation module is greater than that of the motor base. The circuit board is disposed on the first side. The rotor is disposed on the second side. The winding set is disposed on the second side and electrically connected to the circuit board to drive the rotor to rotate. By integrating the motor base and the heat dissipation module into one piece, the assembly process is simplified, and the use of components is eliminated. It benefits to achieve the effects of waterproofing, dustproof and protection.
