[0002] Electric vehicle motors refer to the drive motors used in electric vehicles. They have different forms depending on the environment and frequency of use. Different forms of motors have different characteristics. At present, electric vehicle motors generally use permanent magnet DC motors. Electric vehicle motors can be divided into two categories according to the form of motor power supply: brushed motors and brushless motors; according to the mechanical structure of the motor assembly, they are generally divided into two categories: "toothed" (the motor has a high speed and needs to be reduced by gears) and "toothless" (the motor torque output does not undergo any reduction).

[0003] At present, the existing electric vehicle motors will overheat when used for a long time, but the electric vehicle motors do not have a heat dissipation function, resulting in the heat in the electric vehicle motors cannot be effectively dissipated, which in turn causes the internal components of the electric vehicle motors to age and reduces the service life of the electric vehicle motors.
