Problems solved by technology

However, in the traditional gluing process, there is often too much or too little gluing, too much will be wasted and the appearance will be ugly, too little will affect the sealing effect
[0004] At the same time, in the heat dissipation of the motor, although heat dissipation ribs are designed on the back cover to increase the heat dissipation area, there will be gaps between the heat dissipation ribs and the circuit board assembly, and the heat transfer and heat dissipation effects are often mediocre.

Description

technical field [0001] The invention relates to an outer rotor motor. Background technique [0002] With the continuous development of the industrial age, the application of motors in various fields is becoming more and more extensive. According to the structure, brushless motors can be divided into inner rotor motors and outer rotor motors. The principle is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. An inner rotor motor is a motor whose rotor is inside and the stator is outside. The outer rotor motor is the opposite, the rotor is outside and the stator is inside. [0003] External rotor motors generally include a stator body, a stator assembly, a rotor assembly and a rear cover. The back cover is connected with the stator body, and the circuit board assembly is fixedly installed in the cavity formed by the two. Since the rotor assembly is outside, there will be a certain ga...
