Description of the new type: [Technical field to which the new type belongs] This creation relates to a heat dissipation structure of a motor, especially a structure that utilizes a redundant air guide outside the carbon brush holder of the motor and an air supply device to enhance its internal heat dissipation speed. [Previous technology] Please refer to the first figure, two symmetrical stators 12 are fixed on the inner side of the conventional motor 丄 its casing —. A row of fans 丄 4 is installed on the outer side of its end (or two ends). The hot air generated by the motor 1 in the 〃 and inner chamber 15 is exhausted through the exhaust fan 14 and the exhaust fan 14 is installed. It is set at the-end of the spindle 1 31 of the rotor 13. Its rotation speed is the same as that of the rotor 3. Therefore, its thermal speed is determined by the speed of the rotor 13 is fast and slow. When it is slow, the rotation speed of the exhaust fan 14 is also slow, and the heat dissipation effect provided by it is insufficient, and the hot air generated by °〗 15 cannot be exhausted in a timely manner, and stays in the internal space 15 to increase its temperature continuously. In the end, the W component of the motor is damaged due to overheating. [New content] The white-type motor's heat dissipation method is only based on the exhaust fan installed on the side and the speed is synchronized with the exhaust fan. External effects. 、 / 'Π 5 M284136 In view of the lack of practice, the heat and air generated during the transfer of this creative work _ the mountain is to provide a motor heat dissipation structure that can quickly transport the motor out of the outside, which is mainly based on the-Gongda Perch Brush The housing of the seat is provided with a-guide I female body motor slope guide ^ ««-air supply device, the inside of the court wind device has-disease, its-end has-inlet Π, the other end has an air outlet, the The air supply port can communicate with t # ^, the air port, which is in communication with the internal space of the motor, and hunts cold air outside the pumping device to the internal space of the motor to reduce the temperature of the internal components of the motor. The speed of the space of the coffee-department unit set on the motor end achieves the hot air exhausted from the outside of the motor, thereby improving the efficiency of the rapid heat dissipation of the hot air in its internal space. [Embodiment] The following is the description of the structure and specific embodiments of Zizicai's creation: For a more detailed illustration, please refer to the second, third, and fourth figures. The side of the motor 2 of this creation has a _carbon brush holder shell 2 1 'The content is provided with a carbon brush holder 2 2 and a rotor 2 3 is dragged at the center of the professional riding 2 to form a space between the rotor and the stator provided on the surface of the motor 2-internal space 2 5 The 3 series has a-core and a shaft 2 3 1 and its-end is fixed with an _ exhaust fan 3. The improvement is that: the willow seat shell 2 1 of the motor 2-a side edge is provided with an air guide 2 1 i, which is connected with the The inner part of the motor 2 is connected to 2 5 ′. The upper side of the air guide 2 1! Is connected to the outside and M284136 is installed. One of the air supply device 4 has an air inlet 41, and the other is provided with a fan motor 43 to make it The air outlet 4 2 communicates with the above structure. When the motor 2 is running, the close fan motor 43 will randomly cool the outside * from the air inlet 41 to the inside of the air supply device 4, and then from the air outlet 42 through the air guide.
