なる逆回転軸流電動圧縮機を提供するものである。In the conventional method, the capacity is large because the axial compressor and the electric motor are separate.
In addition, since the stationary blades were used, the energy given by the moving blades was reduced by the stationary blades, resulting in poor efficiency. Therefore, in the counter rotating axial flow electric compressor of the present invention, the shaft (1) is rotatably supported by the casing (9).
A large number of rotating magnetic fields (5) attached to the rotor (6) are installed while sandwiching the rotor (6) alternately, and by passing an electric current, the rotor (6) is guided by the rotating magnetic field (5) and rotates. Then, the reaction force causes the rotating magnetic field (5) to rotate reversely, and 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. A counter rotating axial flow electric compressor is provided in which both blades become moving blades by rotating.

る。Embodiments of the present invention will be described below with reference to the drawings of an induction motor having three phases and three rotors (6). (B) The electric motor portion of the reverse rotation axial flow electric compressor will be described. A direct current is passed from the electric cord (10) to the slip ring (2) via the brush (3) on the shaft (1) rotatably attached to the casing (9) by the bearing (8). The inner cord (11) is U when a coil (5b) wound around an iron core (5a) forms an electromagnet [rotating magnetic field (5)].
The phase magnetic flux penetrates the three rotors (6) and makes a U-turn with the iron cores (5a) of the electromagnets [rotating magnetic field (5)] at both ends.
Go back through the U'phase. Therefore, the U-phase, V-phase and W-phase must be wound clockwise and the U'phase, V'phase and W'phase must be wound left-handedly. Next, when a three-phase alternating current is made to flow and induced by the rotating magnetic field (5), an eddy current flows in the rotor (6) induced by the rotating magnetic field (5), and this current and the rotating magnetic field (5) are induced. Each rotor (6) receives force in the direction of rotation.
Rotates. A rotor blade (7) is attached to each rotor (6), a shaft blade (4) is attached to the rotating magnetic field (5), and when the rotor blade (7) rotates, the reaction force is the shaft blade. They cancel each other out completely with (4) and rotate in opposite directions.
Therefore, no force acts on the casing (9), which allows a lightweight design. (B) The gas flow of the reverse rotation axial flow electric compressor will be described.
The gas that has entered the casing (9) has its axial blades (4) providing circumferential velocity energy and compression energy, and the counter-rotating rotor blades (7) convert the circumferential velocity energy into compression energy, and It is converted into circumferential velocity energy and sent. As a result, almost no circumferential velocity energy remains, but compression energy remains, and a high pressure can be obtained by stacking a large number of shaft vanes (4) and rotor vanes (7). (C) Since the shaft blades (4) are integrated with the shaft (1), the rotating speed of the shaft blades (4) is constant and does not change, but the rotors (6) are independent of each other. Therefore, the induction motor rotates at almost the same speed without load, but when loaded, the rotor (6) individually causes a slip, and the rotation speed of the rotor blade (7) changes. (D) As an example of the use of this counter-rotating axial flow electric compressor, since the axial flow compressor and the electric motor are integrated, a straight pipe type can be used.
It can be used when sending gas over hundreds of kilometers. (E) In a blast furnace used in a steel mill or the like, a reverse rotation axial flow electric compressor is used in such a case because it has a high pressure and has a wide fluctuation range of the air volume and requires a large amount of air.

しないため、軽量な設計が可能となる。As described above, the present invention is one in which the electric motor and the axial compressor are integrated, and has the following effects. (B) Since the electric motor and the axial compressor are integrated, they can be installed in a straight pipe type with a smaller capacity than conventional ones. (B) Since the shaft blade (4) and the rotor blade (7) rotate in opposite directions to each other, the energy of the stationary blades is wasted, and the rotating blades compress in opposite directions. (C) The rotor blades (4) have the same attachment, but the rotor blades (7) have different rotors (6), so that the rotor blades (7) are subject to the load applied to the rotor blades (7). The rotation speed of (6) changes. (D) Since the reaction forces of both blades completely cancel each other out by the rotating magnetic field (5) and the rotor (6) and no force acts on the casing (9), a lightweight design is possible.
