Further, since the stationary blade was used, the energy given by the moving blade was reduced by the stationary blade, so that the efficiency was poor. Therefore, the counter-rotating axial-flow electric compressor of the present invention supports the shaft (1) on the casing (9), and
A large number of rotating magnetic fields (5) are alternately sandwiched between rotors (6), and the rotor (6) is guided by the rotating magnetic field (5) to rotate by passing an electric current. The reaction force causes the rotating magnetic field (5) to rotate in the reverse direction, so that the shaft blade (4) attached to the rotating magnetic field (5) and the rotor blade (7) attached to the rotor (6) are also opposite to each other. An object of the present invention is to provide a counter-rotating axial-flow electric compressor in which both wings become rotor blades by rotating.

る。DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings of an induction motor having three phases and three rotors (6). (A) The motor portion of the counter-rotating axial flow electric compressor will be described. A direct current flows from the electric cord (10) to the slip ring (2) via the brush (3) on the shaft (1) rotatably mounted on the casing (9) by the bearing (8). When the inner cord (11) forms an electromagnet [rotating magnetic field (5)] with the coil (5b) wound around the iron core (5a), U
The phase magnetic flux penetrates through the three rotors (6) and makes a U-turn at the iron core (5a) of the electromagnet [rotating magnetic field (5)] at both ends,
Go back through U 'phase. Therefore, the U-phase, V-phase and W-phase must be wound right-hand, and the U'-phase V'-phase W 'must be wound left-hand. Next, when a three-phase alternating current is passed and induced by the rotating magnetic field (5), an eddy current flows through the rotor (6) induced by the rotating magnetic field (5), and this current and the rotating magnetic field (5) are induced. Each of the rotors (6) receiving a force in the direction of rotation
Rotates. A rotor wing (7) is attached to each rotor (6), and a shaft wing (4) is attached to the rotating magnetic field (5). When the rotor wing (7) rotates, the reaction force is generated by the shaft wing. (4) completely cancel each other and rotate in opposite directions.
Therefore, no force acts on the casing (9), so that a lightweight design is possible. (B) The gas flow of the counter-rotating axial-flow electric compressor will be described.
The gas entering from the casing (9) is such that the shaft blade (4) provides circumferential velocity energy and compression energy, and the counter-rotating rotor blade (7) converts the circumferential velocity energy into compression energy, and further reversely rotates. It is changed to circumferential velocity energy and sent. As a result, almost no circumferential velocity energy remains and compression energy remains, and a high pressure can be obtained by stacking a large number of shaft wings (4) and rotor wings (7). (C) Since the shaft blade (4) is integrated with the shaft (1), the rotation speed of the shaft blade (4) is constant and does not change, but the rotors (6) are individually independent. Therefore, the induction motor rotates at approximately the same speed when there is no load, but when a load is applied, the rotors (6) individually generate slips, and the rotation speed of the rotor blades (7) changes. (D) As an example of use of this counter-rotating axial-flow electric compressor, the axial-flow compressor and the electric motor are integrated, so that it can be made into a straight pipe type.
It can be used when sending gas hundreds of kilometers. (E) In addition, a blast furnace used in a steel mill or the like has a high pressure, has a wide variation in air volume, and requires a large amount of air. In such a case, a reverse-rotating axial flow electric compressor is used.

(B) By rotating the shaft blade (4) and the rotor blade (7) in opposite directions to each other, waste of energy of the stationary blade is eliminated, and compression is performed by the rotating blades rotating in opposite directions. (C) The shaft wings (4) are mounted in the same manner, but the rotor wings (7) are separated from each other by the rotor (6). The rotation speed of (6) changes.
