BRIEF DESCRIPTION OF THE DRAWINGS FIG. In the present invention, as shown in FIG. 1, a rotary drive pump section (rotor section and pump section or fan section) 2 and a magnetic field generating mechanism section (stator section) 1 are completely separated and independent. ) Does not step out because it is a flat AC induction motor that directly drives the rotary plate 7 attached to the pump with the magnetic field from the section.

In the structure of the pump section 2 as shown in FIG. 1, when the rotor 7 of the pump is made of a magnetic material (iron or the like), the rotor blade is made of magnetic flux from the magnetic field generating mechanism (stator) 1. As a result, the rotor can be directly driven to rotate, so that the rotor and the rotor of the motor can be provided as a single unit.

When the rotor 7 is made of a chemical-resistant resin, an acid-resistant resin, or the like, a magnetic plate and a perforated metal plate are embedded in the resin by insert molding or the like to create a strong acid environment or a special environment such as various chemicals. It can be used in

As shown in FIGS. 5, 6, and 7, a rotary drive pump section (rotor section and pump section or fan section) 2
And the magnetic field generating mechanism unit (stator unit) 1 can be used independently, so that the rotary drive pump unit (rotor unit and pump unit or fan unit) is completely sealed in the container (FIGS. 5, 6, and 7) 15. To circulate or transfer liquid, mix,
Stirring, reaction and the like can be performed. The atmosphere in the container may be a vacuum as well as the atmosphere, and it can be used very effectively as a chemical experiment, research, development, and manufacturing apparatus involving dangers such as poisonous gases, strong acids, and bacteria.

The closed container (FIG. 5, FIG. 6, FIG. 7) 17 is most preferably made of non-magnetic material or non-metal. Pump capacity was obtained.

As shown in FIG. 4, the rotary power can be taken out from the rotary drive unit 2 that drives the pump by the pulley 16 attached to the rotary shaft 11 at the same time as the operation of the pump. It can be used as power for chemical experiments, research, development, and manufacturing equipment involving dangerous gases such as poisonous gases, strong acids, and bacteria.

For example, FIG. 1 shows an embodiment of the present invention, and FIG. 1 is a schematic sectional view of an AC energy converter.
In a configuration in which the magnetic field generating mechanism unit 1 and the rotation driving unit 2 are separated and independent from each other, the magnetic field generating mechanism unit 1 includes a rotation driving coil 3, a magnetic core 4 formed of a soft magnetic material at the center of the rotation driving coil 3, and A magnetic pedestal 5 made of a soft magnetic material is provided below the rotation drive coil 3 and the magnetic core 4, and the whole is housed in a storage case 6 to constitute the magnetic field generating mechanism 1.

The rotation drive unit 2 has a rotating plate 7 which is a perforated disk 9 made of a good conductor metal plate (eg, aluminum or copper) and a soft magnetic metal material (iron-based metal, Alnico, etc.).
And a disk 10 made of

The laminated rotating plate 7 is configured such that one surface of the perforated metal plate 9 faces the magnetic field generating mechanism (stator) 1. That is, the one-turn coil portion 9 of the good conductor perforated metal plate is constituted by forming a one-turn coil with a magnetic core around the hole of the good conductor perforated metal plate 9 by the magnetic flux generated from the magnetic field generating mechanism (stator portion) 1.
, An induced voltage is generated and a current flows. A torque is generated by the interaction between the magnetic flux generated from the magnetic field generating mechanism (stator unit) 1 and the current flowing through the one-turn coil, and the rotating plate 7 rotates.

Also, as shown in FIG.
Good conductor perforated metal plate incorporated together (see Fig. 3)
Various shapes are conceivable for the hole shape of No. 9, but as a result of experiments, it has been found that the characteristics of the motor vary depending on the shape of the hole and the number of holes. The number of holes is closely related to the number of coils arranged in the magnetic field generating mechanism 1. The holes 9a shown in FIG. 3 are radially arranged in two stages so that the holes draw concentric circles on the circumference, and the holes are arranged so as to be shifted by 1/2 so as to overlap. With this arrangement, the torque ripple becomes very small.

In the case of 9b shown in FIG. 3, the torque ripple is large, but when power of the same frequency is supplied, the rotational speed becomes 9
greater than a. Further, 9c and 9d exhibited characteristics intermediate between 9a and 9b.

Next, in the AC energy converter,
Rotor part (rotation mechanism part) A structure in which a pump function is provided in 2 shown in FIG. 1 will be described. As shown in FIG. 1, a rotor is manufactured by integrally molding or assembling with several types of parts as a structure constituting a rotor 8 of a pump on a rotating plate 7 of a rotating mechanism 2.

At the center of the rotating plate 7 on which the rotating wings 8 are formed,
There is a shaft 11 serving as a column supporting the rotating plate, and the rotating plate has a structure of rotating around this axis. Around the rotor 8, there are outer frames 12 and 13 serving as a housing of the pump, and the outer frames 12 and 13 are in close contact with each other at a connection point 16 to form a pump chamber 15. Shaft 11 is outer frame 12 and 13
The shaft 11 is fixed so that the shaft 11 is fitted. The rotor is also fixed in the thrust direction by a structure sandwiched between the outer frames 12 and 13.

The rotating plate 7 having the rotating blades incorporated therein is fitted into the space which becomes the pump chamber 15 inside the outer frame 12.
Further, a pump outlet 12c is attached so as to be inscribed in a space serving as a pump chamber 15 inside the outer frame 12. Outer frame 1
3 is provided with a suction port 13a for the pump chamber.
The rotary wing 8 has a fin structure serving as a pump for sucking and delivering liquid and the like. The rotor is constituted by fins arranged on the rotor and walls 8a and 8b sandwiching the fin. When the rotor blades rotate at a high speed together with the rotating plate, a suction force is generated in the pump suction chamber 14 to suck a liquid or the like from the suction port 13a. The sucked liquid or the like is sent by the rotating blade 8 rotating at high speed to the outlet 12c.
Sent out.

According to the present invention, the fins of the pump are formed on the rotary plate of the rotary drive unit even if the flat AC power converter has the same magnetic field generating mechanism and rotary drive unit as the conventional product. By using the rotary drive itself as a pump, a pump having a magnetic field generating mechanism and a rotary drive pump completely separated was obtained. Further, a fan having a completely separated structure of the magnetic field generating mechanism and the rotary drive pump unit was obtained by forming the fin of the fan on the rotary plate of the rotary drive unit instead of the fin of the pump.

Further, by forming a fin of a pump or a fin of a fan on a rotary plate of the rotary drive unit and using the rotary drive unit itself as a pump or a fan, a magnetic field generating mechanism unit and a rotary drive pump unit or a rotary drive fan Since the pump or the fan has a completely separated structure, the rotary drive pump or the rotary drive fan (rotor) is installed in a completely closed container or a container containing liquid as shown in FIGS. And a pump section or a fan section), and a driving magnetic field generating mechanism section (stator section) was placed outside the container to drive the pump or the fan.

The atmosphere in the container may be a vacuum as well as the atmosphere, and it can be used very effectively as a chemical experiment, research, development, and manufacturing apparatus involving dangers such as poisonous gases, strong acids, and bacteria.

The closed vessel is most preferably made of non-magnetic material or non-metal. However, non-magnetic stainless steel or weak magnetic stainless steel or non-magnetic metal has sufficient driving power, pumping ability and fan ability.

In addition, since the rotational power can be taken out simultaneously with the operation of the pump or the fan from the rotary drive that drives the pump or the fan, the rotary drive pump or the rotary drive fan can be arranged in a closed container. It can be used as power for other equipment, machinery, etc. arranged in a closed container.
