[0003] The retrieval authorization announcement number is CN106059196B, which discloses a motor with fast heat dissipation, including a stator, a rotor sleeved in the stator, a rotating shaft pierced on the rotor, and a shell end surface that is sleeved on the stator that is adapted to each other. The casing with ventilation holes and the base with positioning and mounting hole columns in the center, the circuit board is erected on the outside of the base, the drainage fan is fixed on the outside of the end surface of the casing on the rotating shaft, and the stator is sealed with a plastic seal, and the plastic seal faces The end surface on one side of the base is integrally provided with a plastic-encapsulated reinforced connection ring that is attached to the side wall of the housing. The airflow between the bottom plate and the bottom plate is sent into the motor through the vent hole on the bottom plate, and then absorbs the heat in the motor, and then is quickly led out of the motor through the vent hole on the inclined and reinforced hole wall. Although the patent has a strong integrity of the whole motor, the structure Compact, easy to disassemble and assemble, low cost, high strength, good stability, low noise, but the heat dissipation is not good through air holes
[0004] When the existing motor works for a long time, it will generate a lot of heat and cause damage to the motor. At present, many heat dissipation methods are air-cooled or water-cooled to dissipate heat on the surface of the motor. The motor will vibrate violently and cause damage to the motor. In order to solve the above problems, we propose a motor cooling and shock absorbing mechanism
