AI Technical Summary
The cooling fans of existing motors are prone to radial movement when rotating, which can cause the connection with the motor shaft to become loose, generate noise, and lack dust protection.
A cooling fan and dustproof components are installed at the rear of the motor. The mounting part is fixed by a fixing rod and a fixing flange. Combined with a dustproof net and a fixing frame, the cooling and dustproof effects are achieved.
It improves the motor's heat dissipation performance and prevents dust from entering, thus extending the motor's service life.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor technology, and relates to an electric motor, and more particularly to a heat dissipation type motor. Background Technology
[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In circuit diagrams, an electric motor is represented by the letter M, and its main function is to generate driving torque, serving as a power source for electrical appliances or various machines. A generator, represented by the letter G, is represented by the letter G, and its main function is to convert mechanical energy into electrical energy.
[0003] In order to improve heat dissipation, a cooling fan is often installed at the rear end of the motor shaft when the motor is in use. The rotation of the cooling fan promotes airflow and accelerates heat exchange. The cooling fan of the existing motor is usually simply fixed by bolts. The main drawback is that the cooling fan is prone to radial movement when it rotates, which causes the connection between the cooling fan and the motor shaft to loosen, resulting in noise when the motor shaft rotates. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a heat-dissipating motor that is easy to disassemble and has dustproof function.
[0005] The objective of this utility model can be achieved through the following technical solution: A heat-dissipating motor, comprising a motor body, characterized in that a mounting part is provided at the rear end of the motor body, a mounting groove is provided at the rear end of the motor body for mounting the mounting part, a cooling fan for heat dissipation is fixedly installed in the mounting part, an opening for internal ventilation is provided at the rear end of the motor body, a plurality of ventilation holes are provided on the mounting part, a dustproof component is provided between the mounting part and the motor body, the dustproof component consists of a dustproof net and a fixing frame, a groove is provided on the motor body for mounting the dustproof component, two fixing rods are provided at the rear end of the motor body, a positioning hole is provided on the mounting part for the fixing rods to pass through, a fixing flange is fixedly installed on the fixing rod, and the fixing flange is fixedly connected to the fixing rod by threads to fix the mounting part.
[0006] In the aforementioned heat-dissipating motor, the cooling fan consists of a mounting bracket, a rotating shaft, a battery pack, and several cooling fan blades. The mounting section is equipped with a fixing ring for mounting the cooling fan, and the mounting bracket is fixedly mounted on the positioning ring by fixing bolts.
[0007] In one type of heat-dissipating motor described above, the area of the dustproof mesh is larger than the area of the opening.
[0008] In the aforementioned heat-dissipating motor, the fixing rod is integrally formed with the motor body and is respectively located at the upper and lower ends of the mounting part.
[0009] Compared with existing technologies, this heat-dissipating motor provides heat dissipation to the motor's internal components by installing a cooling fan at the rear end of the motor, and a dustproof component is installed between the mounting part and the motor to prevent dust from entering the motor, thereby improving the motor's service life.
