Description

Description Permanent magnet generator Technical field

The present invention relates to a permanent magnet generator that generates electric power using a drive motor. This permanent magnet type generator is suitable for preventing the cogging phenomenon (rotation caused by magnetic attraction when starting the motor power) and for reducing the weight of the generator. This permanent magnet generator is installed in factories, ordinary homes, and so on.

Background art

The structure of a generator (for example, a three-phase motor) includes a stator for generating a rotating magnetic field, a rotor, and a bearing for maintaining the rotor with a fixed gap in the stator. For example, a generator generates electricity in a stator winding when it rotates in a cylindrical stator having a center axis and a rotor force, a stator winding supported by a ball axis. And the electricity generated in the stator winding is passed through the current collector ring brush, resistor, capacitor, etc. ₀

Generally, the stator is a magnet, so it is made up of an iron core through which magnetic flux can easily pass, and a stator winding for making magnetic stone. In this case, a thin gay steel sheet is stacked on the stator iron core in order to prevent loss due to current loss. On the other hand, the rotor, like the stator, is also composed of an iron core with thin gay steel sheets stacked on top of one another and a rotor conductor. The rotor conductor is formed by driving a copper rod into each of a plurality of grooves formed around the rotor iron core, and welding or brazing short-circuit rings to both ends of each copper rod. ing.

By the way, the rotor using the iron core as described above causes a so-called cogging phenomenon with respect to the stator iron core, and as a result, a strong starting torque (electromotive force) as one characteristic of the generator or the motor is generated. Will be needed.

In view of the above, in the case of a generator of this type using an iron core (stator iron core, rotor core) for a stator or a rotor, a technique aimed at reducing or reducing the electromotive force has been proposed. (Japanese Unexamined Patent Publication No. 6-14409, Japanese Unexamined Patent Publication No. ) o

Thus, for example, in the first embodiment disclosed in Japanese Patent Application Laid-Open No. Hei 7-184630, "N-poles and S-poles and annular magnets (rotors) alternately arranged in the circumferential direction of the force" The annular magnet has the same number of poles (for example, 5 pieces) of projection claws (yoke pieces) of a gay element steel plate, and comprises a stator (power generation coil body) having an annular coil therein. Each of the claws is shown a generator with a slit formed in the projection direction so as to reduce the electromotive force.

However, in the generator with the above configuration, although it is possible to reduce the electromotive force (suppress the cogging phenomenon), it is necessary to hold the stator formed of a gay steel plate via a bearing on the center axis. As a result, not only is the generator as a whole heavy due to its structure, but also the magnetic flux density of the ring magnet (rotor) itself is not super strong, so that the generated power can be increased. Did not. There were also problems to be solved in terms of reducing the weight of the generator, increasing the amount of power generation, reducing manufacturing costs, and miniaturizing the equipment.

Therefore, the purpose of the permanent magnet type generator of the present invention is as listed below.

nL

(2) The generator can be reduced in weight.

(3) The efficiency of power generation can be improved. Desirably, the power generated from the stator winding can be increased more than the power consumption of the drive motor.

(4) The production cost can be reduced.

こと The equipment can be downsized.

利点 Obtain the benefits of not using iron. The advantages are low inductance, no iron loss, no magnetic attraction to the rotor, etc.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 and 5 show a first embodiment of the permanent magnet generator X1.

First, 1 is a rectangular base. The base 1 plays a role as a lower lid of an outer cylindrical stator described later. Reference numeral 2 denotes a bearing fixedly embedded in the center of the base 1. The bearing 2 has a mortar-shaped or inverted conical recess 3 on the upper side. The bearing 2 may be a ball bearing appropriately provided on the base 1 or a magnetic levitation system, but it should be devised so as to minimize resistance to the rotating shaft. Further, the bearing 2 does not necessarily need to be embedded in the base 1, and may be provided, for example, in a protruding state on the upper surface of the central portion of the base 1. Further, the bearing 2 may be omitted, and an engaging recess (preferably an inverted conical recess) having a bearing function may be formed in the base 1 itself.

Next, reference numeral 4 denotes a drive motor support member fixedly provided on the base 1. The support member 4 includes a pair of fixed columns 4a, 4a fixedly provided at the center of the left and right ends of the base 1, and a pair of fixed columns 4a, 4a at the upper ends of the fixed columns 4a, 4a. A drive motor 5 is fixedly suspended from the center of the support arm 4b.The drive motor 5 has a projecting output shaft 5a directed downward. I have. The form of the driving member 4 for the driving motor has a portal shape as a whole, but the form is not particularly limited. For example, a cantilevered support arm that supports the drive motor 5 in a vertical state with one hand other than the gate shape may be used. However, the support member 4 must be supported so that the drive motor 5 is located at the center of the inner cylindrical permanent magnet rotor and the outer cylindrical stator, which will be described later.

The upper end 6a is connected to the output shaft 5a of the drive motor 5 via a joint 7, while the lower end 6a is supported by the bearing 2 in a state of being inserted into the inverted conical recess 3. It is an elongated rod-shaped rotating shaft. The rotation shaft 6 is coaxially connected to an output shaft 5 a of the drive motor 5 via a joint 7. The lower end 6 b of the rotating shaft 6 is sharpened like a nail, and rotates in a reverse conical recess 3 in a so-called point contact state, for example, like a piece. When the output shaft 5a of the drive motor 5 is equal to the rotating shaft 6 (when the output shaft 5a is long), the joint 7 is naturally unnecessary.

Reference numeral 10 denotes an inner cylindrical permanent magnet rotor fixedly provided on a rotating shaft 6 as an elongated rod. The permanent magnet rotor 10 includes a wheel-shaped synthetic resin molding 11 fixedly provided at the center of the rotating shaft 6 and an outer cylindrical shaft portion of the synthetic resin molding 11. It is composed of a plurality of permanent magnets 12a, 12b, 12c, and 12d which are annularly mounted on 11a. Each of these permanent magnets 12a has a thickness of about 2 mm. As shown in FIG. 4, the synthetic resin molded body 11 has an outer cylindrical shaft portion 11a having a thickness of about 3 mm, an inner cylindrical fixed shaft portion 11b through which the rotating shaft 6 passes, and It comprises a fixed shaft portion 11b and a connecting portion 11c for radially connecting the outer cylindrical shaft portion 11a, and these portions 11a, 11b, 11c are made of synthetic resin material to prevent oxidation. Molded together.

The plurality of permanent magnets 12a, 12b, 12c, and 12d are cylindrical magnetic coupling bodies that are alternately and annularly arranged in the N-pole and the S-pole in the direction of the arrow as shown in FIG. . Therefore, as long as the plurality of permanent magnets are curved with the same curvature, an arbitrary number such as two, three, or five may be coupled in a ring shape.

The synthetic resin molded body 11 may be formed of a non-magnetic material such as ceramics or a weak magnetic material. Further, although the permanent magnet rotor 10 is formed in a short cylindrical shape in appearance, it may be long cylindrical like the stator. Further, a plurality of permanent magnets 12a, 12b, 12c, 12d may be annularly arranged on the outer peripheral wall surface or the inner peripheral wall surface of the outer cylindrical shaft portion 11a.

Next, reference numeral 15 denotes an outer cylindrical shape (peripheral body portion) fixedly provided on the upper surface of the base 1 so as to form a gap 16 with respect to the outer peripheral wall of the outer cylindrical shaft portion 11a of the permanent magnet rotor 10. Means a synthetic resin stator. Therefore, the lower opening of the stator 15 of this embodiment where the bottom cover may be provided is closed on the upper surface of the base 1, while the upper opening 17 where the upper cover may be provided is provided for the base 1 respectively. In the cross direction. When an upper cover (not shown) is attached to the upper opening 17, a through hole through which air flows is desirably formed. The stator 15 is formed of a material such as titanium, stainless steel, ceramics, hard paper, cloth, or the like, and has a long cylindrical shape. The outer peripheral wall has a predetermined interval in the axial direction or in the longitudinal direction and in the circumferential direction. As a result, a plurality of projecting conductor mounting portions 18 are provided, and a stator winding (power generation coil) 19 is wound around these conductor mounting portions 18. In this embodiment, there are six stator windings 19 as shown in FIG. 3, and the opposing stator windings 19 are appropriately connected to each other.

By the way, in this embodiment, the stator 15 is provided with the cogging of the permanent magnet type generator XI. To prevent the phenomenon as much as possible and to reduce the weight of the generator, it is made of a synthetic resin material, which is an example of a non-magnetic material.

The conductor mounting portion 18 may be provided on the bottom surface of the inner wall of the recess formed on the outer peripheral wall of the stator 15 or may be provided on the inner peripheral wall of the stator 15 as appropriate.

Next, reference numeral 20 denotes a cylindrical shield cover, which covers the entire stator 15. The shield cover 20 is provided with a terminal exit force << to guide the electric cord 22 connected to the stator winding 19 to the outside.

In the above configuration, the driving mode 5 is first activated using a household power supply or a battery (not shown). When the drive motor 5 starts, the rotating shaft 6 rotates together with the output shaft 5a. The rotating shaft 6 rotates smoothly while being guided by the recess 3 of the bearing 2 in a point contact state. The synthetic resin molded body 11 of the permanent magnet rotor 10 constitutes a part of the rotating shaft 6, so to speak, the permanent magnet rotor 10 rotates together with the rotating shaft. Then, since the magnetic field of the permanent magnet rotor 10 crosses the stator winding 19 of the stator 15 in the cross direction, an induced voltage is generated, and electricity is extracted from the stator winding 19. I can do it.

Thus, as shown in the following experimental example, the permanent magnet generator XI can extract a high-efficiency electricity amount with respect to the electricity amount consumed by the drive motor 5.

[Experimental example]

In this section, experimental examples of the present invention will be described. The experiment was performed in accordance with the configuration of the permanent magnet generator X1 (first embodiment). The specifications of the instruments used in the experiment are as follows (see Fig. 31).

First, the limit voltage (Voltage—Range) of the drive module 5 is 12 V, the proper voltage (Noma 1—Votage) is 7.2 V, and the proper load (Noma 1-Load) is 100 gcm. The no-load speed (S pead— at— no— load) is 16,400 rp m, the proper load speed (A t— no rma 1-1 oad-Sp ead) is 14,200 rp m, and the current consumption ( Current) is 2.9 OA, and the model used was DME 44 SA manufactured by Nippon Sabo.

Next, the material of the synthetic resin molded body 11 of the permanent magnet rotor 10 is polycarbonate, its dimensions are 340 X 26 x 59, and the total weight of the permanent magnet rotor 10 is 110 g. W The plurality of permanent magnets 12a to 12d of the permanent magnet rotor 10 include Shin-Etsu rare earth magnets manufactured and sold by Shin-Etsu Chemical Co., Ltd. (product name: N42 of SE REM, maximum energy product of magnetic properties [BH ] max [MGO e]: 41.1, residual magnetic flux density Br [G]: 12,970, coercive force i Hc [Oe]: 15, 720, coercive force bHc [Oe]: 12,540, surface Magnetic flux density [G]: 2,400) was used.

Next, as the material of the outer cylindrical stator 15, polycarbonate was used in the same manner as the synthetic resin molded body 11 of the permanent magnet rotor 10. Its dimensions are 420x380x150. Next, the wire diameter of the stator winding 19 wound around the conductor mounting portion 18 of the outer cylindrical stator 15 is 0.5 Φ, the number of turns is 1,100, and there are six winding points and the stator windings facing each other Lines 19 are connected to each other.

In the experiment with the above specifications, for example, the rotation speed rp m of the drive motor 5, the input voltage V and the input current A (power consumption Wh on the input side), and the output from the stator winding 19 on the stator 15 side And the estimated effective voltage V (output-side generated power Wh). As a result, the permanent magnet generator XI was able to extract highly efficient electricity with respect to the electricity consumed by the drive motor 5.

Here, we explain the technical principle of extracting high-efficiency electricity

First, as is well known, there are Fleming's right-hand rule (1) and Fleming's left-hand rule (2).

Equation (1) is a so-called power generation equation, where voltage e (power generation) = magnetic flux density Bx effective wire length L X moving speed V of wire.

The above equation (2) is a so-called equation of rotational energy. Rotational force (rotational force of drive motor) F = magnetic flux density BX current IX Effective wire length L.

The present invention focuses on these equations, and is configured to maximize the effect on the power generation of the permanent magnet generator X1. Briefly, the same effect can be obtained by rotating the inner cylindrical permanent magnet rotor 10 in the outer cylindrical stator 15 with respect to the electric wire moving speed V in the equation (1). ing.

In other words, a conventional ordinary generator has a small magnetic flux density B, By using it, the magnetic flux density was strengthened and the desired rotational force was created. By the way, in recent years, with remarkable progress in technological innovation, domestic magnet manufacturers such as Sumitomo Special Metals Co., Ltd. and Shin-Etsu Chemical Co., Ltd. have made the maximum energy product of magnetic properties [BH] max [MGOe] power << 48 Until now, it has been produced super strong permanent magnet power. Therefore, the present inventor has adopted this super-strong permanent magnet for the rotor of the permanent magnet generator XI.

Thus, when the permanent magnet generator XI is constructed by combining the inner cylindrical permanent magnet rotor 10 and the stator 15 having a circumferential body in place of the iron core, the magnetic flux density of the above-mentioned formula (1) (41. 1 to 48) exceeded the magnetic flux density (8 to 10) in the above equation (2). As a result, the effective wire length L could be longer than that in the above equation (2). Therefore, in the end, the product of the magnetic flux density B and the effective wire length (coil) L became much larger than the above equation (2). For example, in the above equation (2), the magnetic flux density B (ordinary general motor of 5,000 to 3500 m) is a force of 8 to 10 MGO e. Since a strong permanent magnet is used, the effective wire length L can be much longer.

In the configuration of the permanent magnet generator XI of the present invention, the effective electric wire length (stator winding 19) L of the non-magnetic stator 15 having the peripheral body on the base 1 side is used. Since it is provided at the conductor mounting portion 18 and is disposed with a gap 16 around the annular permanent magnet rotor 10, the weight of the effective wire length L itself is added to the permanent magnet rotor 10 at all. Therefore, the weight of the permanent magnet rotor 10 applied to the rotating shaft 6 directly connected to the output shaft 5 a of the driving motor 5 is also combined with the fact that the driving motor 5 is supported by the support member 4. However, compared to conventional motors, it is very light.

Furthermore, the effective wire length L fixed around the inner cylindrical permanent magnet rotor 10 through the long outer cylindrical stator 15 can be wound as many times as the magnetic flux density B can reach. However, the effective wire length L can be much longer than that of a conventional motor.

As a result, when the rotation speed of the drive motor 5 reaches a certain value, the power consumption (input) of the permanent magnet generator XI to the drive motor 5 is output from the stator winding 19 of the stator 15. The power (output) was successfully improved. In the first embodiment of the present invention, since the output shaft 5a of the drive motor and the rotary shaft 6 are directly connected, the flywheel effect on the annular permanent magnet rotor 10 side depends on the load torque of the drive motor. Although it decreases, the flywheel effect can be expected as the load torque force of the drive motor decreases, so that it is desirable to increase the diameter of the annular permanent magnet rotor 10 and reduce the weight to an appropriate weight. Should.

Next, in the permanent magnet generator X9 of the ninth embodiment shown in FIGS. 26 and 27, the main difference from that of the first embodiment is that the output shaft of the drive motor 5H protrudes. 5a is provided with a drive gear 71, and on the other hand, at the upper end of a rotating shaft 6H that is rotated by the drive force of a drive motor 5H, a driven gear 72 that fits with the drive gear 71 is attached, a so-called gear system. This makes it possible to increase the rotation speed of the permanent magnet rotor 10H.

Thus, the rotating shaft 6H is fixed to the stator 15H, and is supported by an arm-shaped shaft support member 74 having a ball bearing 73 at the center. In this case, rotation The upper end of the shaft 6H may be supported by the support arm 4b of the drive motor support member 4H. The drive gear 71 may be smaller than the driven gear 72.

In this embodiment, the output shaft 5a of the drive motor 5H is not coaxial with the rotary shaft 6H connected via a plurality of gears. By combining the gears 72 with each other, the rotating shaft is rotated at a higher speed in accordance with the ratio of both gears, thereby increasing the rotation speed of the permanent magnet rotor 10H and increasing the power generation of the permanent magnet generator X9. It can be many.

Finally, in the permanent magnet generator X 10 of the tenth embodiment shown in FIGS. 28 to 30, the main differences from the first embodiment are as follows. .

(1) The drive motor 5G is disposed at a position offset from the rotating shaft 6G via the horizontal plate 4bl (= support arm 4b) of the support member 4G. The support member 4G is not a portal-type column as in the first embodiment, but a tubular body having a lower end opening fixedly provided on the upper surface of the base 1G.

The supporting member 4G is composed of a cylindrical portion 4a1 (= fixed column 4b) fixed to the upper surface of the base 1G and a horizontal plate 4b1 for closing the cylindrical portion 4a1. The resulting force The cylindrical portion 4a1 may be a plurality of fixed columns as in the first embodiment.

(2) The rotating shaft 6 G supported via the spherical bearing 80 provided at the center of the bearing 2 G of the base 1 G and the horizontal plate 4 b 1 of the supporting member 4 G serves as the power transmission means 81. Through the drive motor 5G.

In this embodiment, the power transmission means 81 is composed of a small-diameter drive pulley 81a attached to the output shaft 5a of the drive motor 5G, and a large-diameter drive pulley 81a attached to the protruding upper end 6a of the rotary shaft 6G. The driven pulley 8 1b and the driven pulley 8 1b and the driven pulley 8 1b and the driven pulley 8 1a and the driven pulley 8 A circumferential groove is formed in each of 1b.

(3) The belt holding means 82 for applying tension to the belt 81c of the power transmission means 81 is provided on the horizontal plate 4b1 of the support member 4G.

In this embodiment, the belt pressing means 82 is fixed to the solenoid 83 and the distal end of the operating rod 84 of the solenoid, and the upper surface of the force plate, the horizontal plate 4 b 1 and the belt 8 1 A slide plate 85 that moves forward and backward toward c, and a vertical axis 86 The slide plate 85 is guided by a pair of guide pieces 88 provided on the horizontal plate 4b1.

電源 A power supply (battery) 90 is provided on the horizontal plate 4 b 1 of the support member 4 G, and a control device 91 for controlling the belt pressing means 82 and the drive motor 5 G based on the power supply 90 is supported. That is, it is provided on member 4G. The power supply (battery) 90 and the control device 91 may be provided on the base 1G.

The control device 91 has a manual switch 92 for turning the power supply 90 "ON" and "OFF". Then, when the control device 91 sets the manual switch 92 to "ON", the built-in CPU sends signals to the drive motor 5G and the belt pressing means 82, respectively. The drive motor 5G is activated by the power supply 90, while the operating rod 84 of the pressing means 82 is extended. When the operating rod 84 of the solenoid 83 is extended, the presser roller 87 presses the belt 81c of the power transmission means 81, whereby tension is applied to the belt 81c. Then, the driving force of the driving motor 5G is transmitted to the rotating shaft 6G via the belt 81c.

On the other hand, when the control device 91 sets the manual switch 92 to “OFF”, the power supply 90 to the drive motor 5G stops, and the drive motor 5G stops. At the same time, the operating rod 84 of the pressing means 82 is contracted, and the pressing roller 87 force is separated from the belt 81c of the power transmitting means 81. As a result, tension is not applied to the belt 81c, and only the rotating shaft 6G rotates due to inertial force. In this embodiment, the diameter of the permanent magnet rotor 10 G is increased, and a large inertia moment is obtained by the force, the force, and the mass (weight) of the permanent magnet rotor 10 G. Even if it stops, the resistance due to the back electromotive force during power generation can be suppressed by the moment of inertia of the permanent magnet rotor 10 G and the so-called flywheel effect.

Thus, in an experiment based on this embodiment, the number of rotations of the drive motor 5 was 600

When (r.p.m) and the diameter of the permanent magnet rotor 10G is 34 °, the permanent magnet rotor 10G becomes the stator 15G stator winding 1 9 Since the vehicle crossed G at a speed of 636 m / min, it is desirable that an automatic switching circuit be provided in the control device 91, and the belt pressing means 82 and the drive motor 5 be provided at required time intervals. G should be controlled to “OFF” respectively. In the experimental results based on the examples, under no load condition, the total weight of the permanent magnet rotor 10 G was 3 kg, and the diameter of the permanent magnet rotor 10 G was 40 cm, etc. When the belt holding means 82 and the drive motor 5G were turned off, the permanent magnet rotor 10G stopped after about 13 minutes.

That is, the diameter of the permanent magnet rotor 10 G is made larger than that of the first embodiment. In other words, the permanent magnet rotor 10 G has a stator winding 15 G of stator 15 G and a permanent magnet rotor 10 G like the permanent magnet generator X 7 (FIG. 21). The first outer cylindrical shaft portion 11a and the second outer cylindrical shaft portion 11a are provided with a gap 16G inside and outside thereof.

As a result, the permanent magnet rotor 10G has a plurality of first and second permanent magnets 12a, 12b to l2n which are respectively disposed on the upper side and the lower side in the circumferential direction. The outer cylindrical shaft portions 11a, 11a, the inner cylindrical fixed shaft portion 11b through which the rotating shaft 6G passes, the inner cylindrical fixed shaft portion 11b, the first and second The outer cylindrical shaft portion 11a includes a connecting portion 11c, 11c that radially connects the 11a, and the connecting portion 11c includes the outer cylindrical shaft portion 11a and the inner tube. The central portions of the fixed shaft portions 11b are connected to each other.

Industrial applicability

As described above, in the permanent magnet generator of the present invention, when the rotation speed of the drive motor reaches a certain value, the power consumption of the drive motor of the permanent magnet generator is reduced by the output from the stator winding of the stator. Since the generated power is more efficient, a permanent magnet type generator can be electrically connected to a control device (not shown), a power storage device, a resistor, and the like, and can be used in factories, ordinary homes, and the like.

The present invention has the following effects.

(1) Since the stator is made of non-magnetic material, so-called cogging is very small.

(2) Since the rotor is formed in the shape of an inner cylinder and has no winding as in the conventional case, the generator can be lightened as a whole in terms of structure.

(3) As is evident from the experimental results using the inner cylindrical permanent magnet rotor, the generated power that can be extracted from the stator winding is larger than the power consumption of the drive motor. Therefore

, While increasing the amount of power generation, and generating excess electricity from permanent magnet generators. They can also be removed.

(4) For example, in the tenth embodiment, the diameter of the permanent magnet rotor is increased, and a large inertia moment is obtained by the mass (weight) of the permanent magnet rotor. In addition, due to the moment of inertia of the permanent magnet rotor and the so-called flywheel effect, the resistance due to the back electromotive force during power generation is suppressed. You can continue.

(5) It can be manufactured inexpensively and has no running cost.

(6) The size can be reduced.

(7) For example, in the first embodiment, when the drive motor is supported in the vertical direction, and the force, force, and rotation axis are rotated in a so-called point contact state in the inverted conical recess of the base,

The load on the rotational force of the drive motor is small.
