[0002] Electric scooters are portable, short-distance vehicles powered by electricity. Their lightweight, flexible, and environmentally friendly features have made them a popular choice for urban commuting and leisure travel. The electric scooter's motor is one of its core components, converting electrical energy into mechanical energy to propel the scooter. Electric scooter motors are often driven by in-wheel motors. The present invention relates to a scooter motor driven by an in-wheel motor.
[0003] During the use of scooter motors, the integrated devices inside are relatively dense and the heat generated by the motors is relatively large. Due to the special installation position of the hub motors, their shells need to have certain water and impact resistance and are usually designed to be relatively closed. The long-term use of electric scooter motors can easily lead to motor damage. Part of the heat dissipation method is through external cooling fans. Due to the special position of the motors, the cooling fans are easily contaminated and affect the heat dissipation. Summary of the Invention
