PURPOSE: A cooling structure of a motor is provided to improve energy efficiency and lengthen a life by preventing motor lowering by heat from motor coil resistance. CONSTITUTION: An air guide(351) is inserted to a rotor vent(330), and moved to the left of the vent in stopping a rotor(320). The rotor is moved to the left in changing rotational direction of a motor, and the motor is rotated by pushing the air guide in contacting the air guide to the right of the vent. The rotor is moved to the right in rotating the motor reversely according to rotation cycle, and the air guide is placed to guide air into the motor to the maximum against rotation of the motor. The motor is turned in pushing the air guide. The air guide is moved automatically according to the rotation of the motor, and the coil is radiated and cooled by moving air into the vent and the coil of the motor. The air is efficiently guided into the vent by forming an inclined face in the air guide or the arc air guide. The motor is rotated forward and reversely by symmetrizing the inclined surface or the arc. |
