BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

 In all the drawings, the same reference numerals represent the same or equivalent members.

 First, the logic that forms the gist of the present invention will be developed.

 Since the stator (rotator) and rotor (rotor) materials of current generators are magnetic materials, the rotor rotates and starts power generation based on the action and reaction. Requires a larger motive power than the power generation output at the time of start-up operation. For example, in terms of aluminum (or duralumin) and magnets, two round aluminum discs of about 20 cm are rotatably supported facing each other, and six permanent magnets of about 4 cm are mounted on one side, and the central angle is 60 It is obvious that if the disk is mounted radially and rotated, the other aluminum disk will start to rotate due to the generation of eddy current.

The present invention focuses on the eddy current as a key point and makes the eddy current close to zero, and focuses on the structure and material of an unprecedented generator. Therefore, the material of the stator of the present invention is made of aluminum. The rotor is made of the same aluminum material, and permanent magnets (N, S) are installed and mounted. [Embodiment 1]

 First, the configuration will be described.

 FIG. 1 is a diagram showing a configuration of a first embodiment corresponding to the present invention described in claims 1 and 3.

 FIG. 1 is a diagram showing a configuration of Embodiment 1 of the present invention. Fig. 1 (a) is a front sectional view of the generator (stator / rotor) cut away at right angles to the rotation axis, and Fig. 1 (b) is a side view of the rotor.

 1 is a stator made by die-casting aluminum [Die-casting], 3 is a slot for winding and inserting a stator winding [not shown], and 3 is first established by the present invention. A cut surface represented by a notch line, 4 is a normal plastic outer frame (yoke) that forms a magnetic material, 5 is a rotating shaft that rotates by instructing a rotor, and 6 is an aluminum die casting. Consisting of a rotor,

7 is a permanent magnet, 8 is a connecting means (screw) for connecting the stator 1 and the outer frame 4 o

 The aluminum thus created is die-casted. A notch [cut surface] 2 is cut out from the bottom of the slot 3 toward the outer peripheral surface of the stator 1 with the stator 1 forming a die casting in the direction of the rotation axis. The generation of eddy current in the circumferential direction of rotation is prevented by providing a gap having electrical resistance so as to interrupt the current in the notch 2. Then, a wooden mold is prepared from aluminum material, and the slot 3 in which the stator winding (coil) is to be formed is formed in the same shape as a normal generator.

 Therefore, the magnetic flux generated from the permanent magnet 7 of the rotor 6 interferes with the magnetic flux based on the eddy current that would occur in the ordinary stator 1 during rotation, especially at startup, which hinders the rotation of the rotor 6. The effect as reactance is lost.

That is, since the stator 1 is a single aluminum object, As it is, an eddy current is generated in the stator 1 from the rotating magnetic field of the aluminum and the permanent magnet 7 of the rotor 6, and the coercive force of the rotor 6 causes the rotor 6 to rotate and start, which requires more energy than that. The engine cannot be rotated by the motive power during normal operation.

 Therefore, as one of means for reducing the eddy current to zero, a cut surface is formed from the bottom of each slot 3 toward the outer peripheral surface of the stator 1. In this way, even a generator with a considerable capacity or one small finger can be used to start and rotate lightly from stop.

FIG. 2 shows a connection diagram of a stator winding applied to the first embodiment. The connection of each winding in Fig. 2 is a double star connection. For example, if U ₂ V,, V ₂ and, W ₂ are connected to each other and connected, the three-phase AC power generation voltage is generated from them. Derived. Note that Ζ>, Z ₂ are assumed to be neutral.

 FIG. 3 is a front view of the rotor. Also indicates the direction of the magnetic poles of the permanent magnet. This permanent magnet has a strong magnetic force, such as neodymium [trade name], and has a performance three times or more the usual coercive force. Furthermore, Neomax [trade name, manufactured by Sumitomo Metal Industries, Ltd., magnetic flux density in the air of 300 to 1500 Gauss] is applied to the permanent magnet of the present invention, and a conventional funilite magnet is used. In contrast, it has about 100 times the magnetic energy of the same size.

By the way, as shown in FIGS. 2 and 3, the form of the stator winding and the number of poles of the permanent magnet mounted on the rotor, such as 4 poles, are merely examples, and are not limited thereto. FIG. 4 is a cross-sectional view illustrating a mode as a generator device according to the first embodiment. In Fig. 4, 6c and 6d are rotor side plates, 6x and 6y are rotor support frames, 9 is a coil end of a stator winding, 10 is a prime mover (here, a small motor), 11a , lib is a pulley, 1 is 2 Tie belts, 13a, 13b, and 13c are bearings, and 14 and 15 are frameworks composed of pipes and the like.

 [Embodiment 2]

 Figure 5 shows two rotors cascaded along one rotating shaft and fixed in a skewered fashion, and the concentrically wound stator halves are positioned 180 degrees apart from each other. It is a side sectional view showing other embodiments arranged and connected in series. Then, the starting of the rotating shaft having the two rotors 6a and 6b in such an arrangement is smooth as described above due to a decrease in excessive reluctance. Furthermore, if the two rotors 6a and 6b are replaced with one rotor 60 (abbreviated as a dashed hatched portion) and started, almost only the mechanical friction resistance is used as the starting resistance. This embodiment enables extremely light starting rotation. Embodiment 2 is an effective means for determining the material of the stator, the output of the starting motor, and the like. That is, according to the second embodiment, it was certainly proved that the material of the stator was reinforced, and even plastic or duralumin had good start-up and power generation capabilities.

 In particular, it was confirmed that the power generation output was further improved in the case of a stator made of reinforced plastic (of course, the outer frame (yoke) is made of a magnetic material). FIG. 6 is a diagram illustrating another embodiment of the present invention in which circular band-shaped magnetic plates are provided at both left and right ends in the axial direction of the stator. FIG. 6A is a side sectional view, and FIG. 6B is a front view.

 The circular strip-shaped magnetic plates 16a and 16b shown in Fig. 6 have a width of approximately 0.55 to 0.65 of the axial width of the coil 9 of the stator winding, and the diameter of the circular shape is approximately It is formed equal to the diameter of the work, and is placed on the both end faces of the stator with a small gap.

For example, regarding the output of the generator of claim 1, By attaching the magnetic plates 16a and 16b, a remarkable effect is shown in which the generated voltage can be expected to rise from 80 V to 100 V without burdening the starting side.

 In this case, when the generator output capacity is 5 KW and exceeds its output and exceeds the current capacity of the stator winding, those circular strip-shaped magnetic plates 16a

, 16b resulted in fever.

 [Embodiment 3]

 Until now, all explanations have been given in the form of a rotating body.However, the stator is developed in a state where it is cut in a part of the circumference in the axial direction. It is clear that if the mover is moved in the direction of its deployment on the stator with a small gap between them, a generator voltage is generated on the stator winding and a linear generator can be obtained. Some of them are described below. FIG. 7 is a diagram illustrating a linear generator that applies an exciting current to an electromagnetic induction source.

 FIG. 7 (a) is a perspective view thereof, and FIG. 7 (b) is a partially enlarged side sectional view thereof. The stator 1 is formed by die-casting a rectangular parallelepiped aluminum plate, has slots 3 opened in the width direction, and has windings 9 that lead out the power output at a uniform pitch in the length direction. a (the effective part of the coil end 9) is provided with a plurality of slots 3 for winding.

 Notches are vertically cut from the bottom of the plurality of slots 3 to the outer surface of the stator.A cut surface 2 is inserted, and a yoke 4 made of a magnetic material that abuts on and surrounds the outer peripheral surface of the stator 1. Is provided.

 The mover 1 a is formed in exactly the same member and shape as the stator 1, and has means for applying an exciting current for generating electromagnetic induction in the mover winding 9 c (effective portion of the coil end 9 b). are doing.

The surface of the slot of the mover is the surface of the slot of the stator. And a support mechanism [not shown] that enables the mover 1a to reciprocate in the left and right directions in the longitudinal direction.

 It should be noted that the illustrated notch / cut surface 2 in the vertical direction is not necessarily provided on both the stator 1 and the mover 1a, but may be provided on either one of them.

 It is useful as a generator [electric generator] that can generate a considerable amount of electric energy with a small amount of starting torque and generated energy from a small current.

 By the way, instead of giving a linear motion to the mover 1a, a constant AC current is applied to the winding 9c of each slot 3a by an electronic circuit (not shown), for example, which is shown in the drawing. By slightly shifting the time between 3a, that is, by changing the current phase, a mechanism that just generates a rotating magnetic field can be created in a stationary state.

 Such means are the same for the embodiment described below and shown in FIG.

 Fig. 8 is a diagram showing a linear generator that is a flat development of the embodiment of Fig. 1. Fig. 8 (a) is a perspective view, and Fig. 8 (b) is a partially enlarged side sectional view. The mover 1 a holding the permanent magnet 7 and its outer frame 4 a have the same material and configuration as the stator 1 and its outer frame 4.

 That is, the stator 1 is a rectangular parallelepiped plate-shaped aluminum die-caster, has slots 3 in the width direction, and has windings that derive the power generation output with a uniform pitch in the length direction. A number of slots 3 for winding a are provided. Notch vertically from the bottom of the plurality of slots 3 to the outer surface of the stator.

The mover 1a is made of die-cast rectangular parallelepiped aluminum, has an appropriate width in the width direction, and has a plurality of permanent magnets 7 alternately having different magnetic poles at a uniform pitch in the length direction. It is arranged as follows. The surface of the permanent magnet 7 of the mover 1a faces the surface of the slot 3 of the stator 1 via a small gap G, and the mover 1a can reciprocate left and right in the longitudinal direction. This is a configuration including a support mechanism [not shown].

 In this way, the linear motion of the mover 1a with a small amount of starting energy effectively extracts the magnetic energy held by the permanent magnet 7 and obtains a considerably large power generation output.

 [Embodiment 4]

 FIG. 9 shows one of the novel embodiments of the present invention. FIG. 9 (a) is a perspective view showing the whole, and FIG. 9 (b) is a partially enlarged side sectional view.

 The stator 1 is a rectangular parallelepiped, plate-like material made of ferrite or the like, has slots 3 opened in the width direction, and has windings 9 that lead out the power generation output at a uniform pitch in the length direction. a is equipped with multiple slots 3 for winding

 A stator outer frame plate 4 made of plastic such as vinyl chloride or polyester is provided in contact with the bottom of the plurality of slots 3.

 The mover 1a is formed in exactly the same member and shape as the stator 1, and includes means for applying an exciting current for generating electromagnetic induction to the mover winding 9c.

 The surface of the slot 3a of the mover 1a is formed facing the surface of the slot 3 of the stator 1 via a small gap G, and the mover 1a reciprocates left and right in the length direction. The alternator is configured with a support mechanism that enables the following.

 Thus, the excessive reactance at the time of starting is reduced, and the mover is started smoothly, and an AC generator with high power generation efficiency can be obtained.

Further, Fig. 10 is a diagram showing the means in which the winding part of the mover in Fig. 9 is replaced with a permanent magnet. Fig. 10 (a) is a perspective view showing the whole, and Fig. 10 (b) is a partially enlarged view. ~ side It is sectional drawing.

 The stator 1 is formed of a rectangular parallelepiped flat plate, has slots 3 opened in the width direction, and has windings 9a for leading out the power generation output at a uniform pitch in the length direction. There are multiple slots 3 to be mounted once.

 A stator outer frame plate 4 made of plastic such as vinyl chloride or polyester is provided in contact with the bottom of the plurality of slots 3.

 The mover 1 a has a plurality of sets in which rectangular parallelepiped ferrites and rectangular parallelepiped permanent magnets 7 are alternately joined in a sandwich shape, and the permanent magnets 7 are N-pole or S-pole with a uniform pitch in the length direction. The pole types are alternately arranged and integrated to form a flat rectangular parallelepiped.

 The permanent magnet 7 opposes the surface of the stator 1 via a small gap G, and the mover 1a has a support mechanism (not shown) that enables reciprocating movement to the left and right in the longitudinal direction. It is configured.

 Further, as shown in FIG. 10, this alternator forms a set in which the polarity arrangement of the permanent magnet 7 is N-pole, N-pole or S-pole, S-pole and a plurality of (for example, two) continuous. With this configuration, the pole types of those pairs are arranged alternately. With this configuration, the synergistic effect of the small starting energy and the supermagnetic energy of the permanent magnet appears remarkably, and the smooth starting and the output voltage with a regular waveform are realized. As a result, it is possible to obtain a special effect that one of the most excellent AC generators in terms of starting torque, power generation efficiency, weight, etc. can be obtained as a linear generator. If it is provided, it becomes a DC generator, and it is also clear that it can be usefully operated in the same form as a motor.

In this way, the present invention provides a small-sized mobile As a step generator, in mobiles where energy is not fully or continuously available, or is unfavorable due to load restrictions, energy supply from other energy sources is not sufficient. Also, the energy stored in the permanent magnet of the rotor (moving body) is started in a state with extremely little reactance, the energy of the permanent magnet is added and derived, and the number is calculated based on the small energy from the prime mover. This means that it can be operated with twice the energy.

 By doing so, the eddy current generated in the stator at the time of start-up becomes almost nil, and the magnetic field from the permanent magnet accompanying the rotation intersects with the stator winding as a rotating magnetic field to induce a sine wave AC voltage. As a result, a considerable amount of energy was required at the time of start-up, so a start-up prime mover that had an output exceeding the torque required to rotate the running generator was required. It is particularly suitable for applications that require starting, running, and stopping by the prime mover using only the torque that rotates the machine, especially for applications that have strict restrictions on the loading capacity of small fishing boats and other conditions that require the lowest cost. The effect can be achieved.

 For example, regarding the output of the generator according to claim 1, by attaching the magnetic band-shaped magnetic plate in this way, the load on the starting side is reduced from 80 V to 100 V without placing a burden on the starting side. This shows the remarkable effect of increasing the output that can be expected. Industrial applicability

An AC generator, in which a stator is opposed to the outer peripheral surface of the rotor via a gap, and the material of the stator is aluminum. It is composed of a die cast, and has a plurality of slots in the center of which is wound a winding for drawing out the power generation output on the inner circumferential surface of the perforated circle. A notch in the axial direction from the bottom of the rotor to the outer peripheral surface of the stator, and a yoke formed of a magnetic material that abuts on and surrounds the outer peripheral surface of the stator. Permanent magnets formed by aluminum die-casting and fixedly mounted on the outer peripheral surface of the rotor are opposed to the inner peripheral surface of the stator with a small gap.

 As a result, the eddy current generated in the stator at startup is almost nil, and the magnetic field from the permanent magnet accompanying rotation intersects with the stator windings to induce a sine-wave AC voltage as a rotating magnetic field. Therefore, since a considerable amount of energy was required at the time of start-up, a start-up prime mover that had an output of more than the torque to rotate the running generator was required. It can be started, operated, and stopped by the prime mover using only the torque that rotates the generator, especially for applications that have strict restrictions on the loading capacity of small fishing boats, etc., and conditions that must be minimum in terms of cost. The special effect of optimum can be achieved.

A circular strip having an axial length of approximately 0.55 to 0.75 of the coil end of the coil end is abutted or inserted through a small gap, for example, the output of the generator of claim 1 By attaching a circular strip-shaped magnetic plate made of a magnetic material as described above, a remarkable effect can be obtained in that the generated voltage can be expected to rise from 80 V to 100 V without imposing a load on the starting side. -Furthermore, in the present invention, in the alternator described in the first section, since the stator yoke is made of an animal, the alternator is usually produced. It can be implemented in accordance with the production of generators, and can protect against and deal with any external infringement.

 According to the present invention, in the alternator according to the first aspect, two rotors are mounted in parallel with the rotating shaft, and one stator is split in half to have a mechanical angle of 180 °. It is installed at a staggered position, and the stator windings are connected to derive the power generation output.Therefore, excessive reactance does not occur at startup, and the number of rotors is reduced to one or two. This has a significant effect on capacity reduction.

 According to the present invention, in the alternator according to the first to second aspects, the stator is developed in a linear plate shape together with the yoke, and the rotor is provided with a slight gap on the winding side of the stator. By developing the stator and rotor material and shape in various ways by deploying them in a linear plate shape facing each other, the conversion from the rotating magnetic field to the linear moving magnetic field is smoothly performed, and at the time of startup It has a remarkable effect of eliminating excessive reluctance, enabling linear drive and starting of power generation with small energy, and realizing a small generator with excellent power generation efficiency. That is, the linear generator of the present invention has an effect that the conversion from the rotating magnetic field to the linear moving magnetic field is performed smoothly, and the linear drive and the power generation can be started with small energy. It is useful as a generator that can acquire a considerable amount of electric energy by generating electricity from a small amount of startup energy and a small current from the configuration. This is a means by which magnetic energy held by permanent magnets can be effectively extracted from the movement, and a large power output can be obtained.
