PURPOSE: A motor cooling propeller is provided to expand the life expectancy of a motor by integrating the rotary shaft of the motor and a propeller in order to cool the heat generated at the motor. CONSTITUTION: A small-sized propeller(300) is mounted at the rotary shaft(200) of a motor(100). A fixing unit fixes the rotary shaft of the motor and the small-sized propeller. When the rotary shaft of the motor is rotated, the small-sized propeller is simultaneously rotated. Wind, generated from the rotation of the small-sized propeller, is transferred to the motor, and the heat generated at the motor is cooled. |
