[0002] A motor, full name electric motor, is a device that converts electrical energy into mechanical energy. After retrieval, the application number "CN202021625992.4" discloses "a servo motor with explosion-proof function", which records that "the utility model arranges a first fan blade on the left side of the shell, and opens an air inlet hole on the left side of the first protective cover, so that the first fan can bring the outside cold air into the interior of the shell, and then the second fan blade on the right side of the shell takes out the heat inside the shell, and a heat dissipation cavity is arranged on the shell, so that the heat inside the shell can contact the shell in the heat dissipation cavity, and then the heat is dissipated through the heat dissipation fins. Combining all the above methods, the heat inside the shell can be effectively dissipated, so as to achieve the explosion-proof function and improve the safety of the device". By arranging a first fan blade on the left side of the shell and opening an air inlet hole on the left side of the first protective cover, the first fan can bring the outside cold air into the interior of the shell, and then the second fan blade on the right side of the shell takes out the heat inside the shell, and a heat dissipation cavity is arranged on the shell, so that the heat inside the shell can contact the shell in the heat dissipation cavity, and indeed the heat is dissipated through the heat dissipation fins. Combining all the above methods, the heat inside the shell can be effectively dissipated, so as to achieve the explosion-proof function and improve the safety of the device. However, the above comparative document still has the following problems in actual use:
