<P>PROBLEM TO BE SOLVED: To solve problems of a conventional reverse-rotation axial flow electric compressor comprising an axial flow compressor integrated with a motor and moving blades which reversely rotate with respect to each other without using stator blades to improve efficiency, that an output of an induction motor is limited, a cage-type rotor is troublesome in manufacturing, and cost is increased, and then to change the cage-type rotor of a rotor to a permanent magnet to enable the rotor to rotate using an inverter. Ž<P>SOLUTION: In a double reverse rotation type synchronous blower, the rotor (6) is equipped with a north pole and a south pole of the permanent magnet according to the pole number of a rotating magnet field (5). An axial blade (4) is mounted to the periphery of the rotating magnetic field (5), and a rotor blade (7) is mounted to the periphery of the rotor (6). The inverter is used for a power source.
