However, when using the existing motor, it is found that the fan blade of the existing motor is usually directly fixed on the output shaft. When the output shaft rotates, the fan blade rotates to dissipate heat. However, when the motor temperature is low and no heat dissipation is required, the fan blade still follows the output. The rotation of the shaft causes unnecessary loss of the output power of the motor and reduces the conversion efficiency of electric energy; at the same time, the existing motor only uses the rotating fan blades to cool the motor, and the fan blades can achieve poor heat dissipation effect.
