Abstract

The utility model discloses a motor with a heat dissipation structure, which belongs to the technical field of motor devices and comprises a base, a stator and a rotor are arranged in the base, a rotating shaft is fixedly connected onto the rotor, two ends of the rotating shaft extend out of the base and are rotatably connected with the base, and a fan assembly is arranged on one side of the base and is connected with the rotating shaft. A water tank is arranged on the side, close to the fan assembly, of the machine base and internally provided with a water pump, and a gap is formed between the water tank and the fan assembly. A hollow water jacket fixedly sleeves the machine base, a plurality of U-shaped water flow channels are formed in the water jacket, a plurality of water inlets and a plurality of water outlets are formed in the side, close to the water tank, of the water jacket, the water inlets communicate with one ends of the U-shaped water flow channels correspondingly, and the water outlets communicate with the ends, away from the water inlets, of the U-shaped water flow channels correspondingly; the water inlets are communicated with the water outlet end of the water pump, and the water outlets are communicated with the water tank. According to the utility model, air-cooling heat dissipation and water-cooling heat dissipation can be simultaneously realized, and the heat dissipation effect of the motor is improved.
