Description

Technical Field

[0002] A micro-motor, full name "miniature motor", refers to a motor with a diameter less than 160 mm or a rated power less than 750 mW. It is often used in control systems or driving mechanical loads to realize functions such as detection, analysis and operation, amplification, execution or conversion of electromechanical signals or energy. The working principle of the micro-motor mainly involves the principles of electromagnetic induction and electromagnetic force. When the micro-motor is powered on, an electric current will generate a magnetic field in the coil, and this magnetic field will interact with the magnet to generate an electromagnetic force. This electromagnetic force will drive the rotation of the micro-motor to achieve the mutual conversion between mechanical energy and electrical energy.

[0003] Most micro-motors have a certain heat dissipation ability, and this heat dissipation ability mainly comes from the heat dissipation effect of the motor itself. Due to the small size and high power density of the micro-motor, its heat dissipation effect is often poor. In order to improve the heat dissipation effect, some micro-motors use external heat dissipation devices such as heat dissipation fans. Most of the heat dissipation fans used are installed on the micro-motor with fixing parts (such as screws, buckles, etc.). Subsequently, when disassembling, specific tools are required to disassemble the heat dissipation fan, and the operation is relatively complicated. Therefore, a micro-motor is proposed.
