Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a contact heat dissipation motor. Background technique [0002] Motor (English: Electricmachinery, commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. In the circuit, it is represented by the letter M (the old standard is D). Its main function is to generate driving torque as a power source for electrical appliances or various machinery. The generator is represented by the letter G in the circuit. Its main function is to convert electrical energy into mechanical energy. [0003] However, the equipment that uses the motor as power will generate heat when it is working. The heat is caused by poor ventilation of the motor and a lot of dust inside.

Problems solved by technology

[0003] However, the equipment that uses the motor as power will generate heat when it is working. The heat is caused by poor ventilation of the motor and a lot of dust inside. In order to improve the heat dissipation performance of the traditional motor, a fan is usually installed inside the motor to speed up the heat dissipation by taking away the hot air through the airflow, but the heat dissipation effect of the heat radiation is poor; in addition, when the fan is used for heat dissipation, in order to reduce dust entering The motor casing, often the vents on the motor casing are set on the side wall of the fan outlet end. When the fan rotates, a negative pressure will be formed inside the motor casing. At this time, the air flowing into the motor casing and the air flowing to the outside of the motor casing The air passes through the ventilation openings, resulting in a small wind power of the fan and poor heat dissipation performance; if an air intake hole is provided on the peripheral surface of the motor casing, it is easy to cause dust to enter when the motor is not in use
