The present invention relates to an air blower rotating a rotor, comprising: a first motor; a first housing combined with the first motor and having an exit, which rotates a rotor; a first impeller placed inside the first housing, rotated by the operation of the first motor, and blowing air to the exit of the first housing; a second motor combined with the first housing; a second housing combined with the first housing; a second impeller combined with the second motor, rotated by the operation of the second motor, and placed inside the second housing; and multiple second blowing pipes combined with the second housing and being a path for the air blown from the second impeller, wherein any one path among the second blowing pipes communicates with the inside of the first motor and increases the efficiency of the first motor by removing frictional heat generated in the first motor, and the other path among the second blowing pipes communicates with the exit of the first housing and increases the intensity of the air blown through the exit. The motors have no decreases in the efficiency even if the motors are used for a long time as the frictional heat of the motor for blowing air is cooled. The efficiency of kinetic energy does not decrease as a copper wire covered with nano-ceramics is used as the windings of the motors, the generated heat of kinetic energy is not transmitted to covering while being conducted through a copper wire with high thermal conductivity when the motors are used for a long time, and heat generation is inhibited in the whole windings. |
