Analysis of heat dissipation principle of hub motor

The heat dissipation principle of the hub motor is that during the driving of the electric vehicle, the hub motor will dissipate heat to the outside, and part of the heat will be taken away by the air through convection heat dissipation; The proportion of heat dissipation is small and negligible; the remaining part of the heat causes the temperature rise of the motor. The airflow of convection heat dissipation is composed of the internal flow and the external flow of the electric vehicle. The front flow passes through the air intake grille, and part of it passes through the front condenser and radiator to become a high-temperature cooling gas, which flows from the rear of the front wheels and the chassis to the rear of the car. The air bypasses the body and flows into the wheels from outside the front wheels, creating an outflow cooling air.
