The rotary disk 24 is shown in FIGS. 1, 2 and 4, and is a disk shape as a whole, and is attached to the lower end portion of the rotary shaft 4. That is, the turntable 24 has a dish-shaped main body formed with screw insertion holes for fixing 15 sets of first to third magnets 28 to 30 described later. These screw insertion holes are arranged at intervals corresponding to a pair of screw holes preliminarily formed in each magnet 28 to 30, and each pair is oriented in the radial direction, corresponding to 15 sets of magnets. Turntable 2 required
4 is provided along the circumferential direction. In addition, the lower end of the rotary shaft 4 is connected to the connecting portion 17 mounted in the center of the turntable 24, and is rotatably suspended. In addition,
The turntable 24 has a diameter Φ of 20 depending on the size of the device.
It is manufactured in the range of 0 mm to 2200 mm. On the other hand, the fixed platen 25 is shown in FIGS. 1, 3 and 4, and has a disk shape having substantially the same diameter as that of the rotary plate 24, is attached to the slide member 23, and is arranged on the concentric circle of the rotary plate 24 to face each other. Has been done. The slide member 23 has a rectangular shape, and an insertion hole for the rotary shaft 4 is formed at the center, and a screw hole for screwing the guide rod 22 of the magnet spacing adjusting mechanism 17 is formed at each corner. The slide member 23 has a screw insertion hole for fixing 15 sets of the first to third magnets 28 to 30 in a circular portion similar to the main body of the rotary disk 24. These screw insertion holes have an interval corresponding to a pair of two screw holes preliminarily formed in each magnet 28-30, and each pair has a radial direction.
A required number of magnets corresponding to five sets of magnets are provided along the circumferential direction of the circular portion of the fixed platen 25. The slide member 23 also has a length L of 200 mm to 2 depending on the size of the device.
It is manufactured in the range of 400 mm.

As shown in FIG. 1, the magnet spacing adjusting mechanism 17 is provided with an adjusting motor 18, a pair of gearboxes 19 and 20, and a guide rod 22, and the spacing between the fixed platen 25 and the rotary plate 24 is arbitrarily set. It has an adjustable structure. The adjustment motor 18 is fixed on the base 1h near the left vertical frame 1b, and its shaft is connected to one of the gearboxes 19 side. The adjustment motor 18 is configured to be rotationally controlled by receiving a signal from the adjustment motor drive unit 36 controlled by the control unit 40. The gearboxes 19 and 20 have transmission gears housed therein, and are fixed on the base 1h at a predetermined interval. And
The gearboxes 19 and 20 are connected to each other by a shaft 21, and the lower end of a guide rod 22 is connected to each of them. This guide rod 22 has a round bar shape,
A screw part is engraved on the outer peripheral surface. These guide rods 22 have a length that is close to the base 1h side and the turntable 24 side, and their lower ends are connected and held by the gearboxes 19 and 20, and are erected rotatably. Then, when the screw holes of the slide member 23 are respectively screwed into the respective guide rods 22, the fixed platen 25 can be moved up and down along with the rotation. That is, when the adjusting motor 18 is rotated in the forward direction, the gears in the gearboxes 19 and 20 rotate together with the shaft thereof, and the guide rods 22 are interlocked. Then, the slide member 23 screwed to this moves upward, and the fixed platen 25 also rises. For this reason, the fixed platen 25 approaches the rotary platen 24 side, and the gap between the fixed side magnet group 27 and the rotary side magnet group 26 is narrowed. On the other hand, when the adjustment motor 18 is rotated in the reverse direction, the slide member 23 moves downward and the fixed platen 25 also descends. Therefore, the fixed platen 25 is separated from the rotary platen 24 side and the fixed side magnet group 27 is formed.
And the rotation-side magnet group 26 also widen. As a result, the magnetic force between the magnet groups 26 and 27 can be adjusted to adjust the strength of the repulsive force.

The rotating-side magnet group 26 is shown in FIGS. 4 to 7, and a plurality of sets of the first, second, and third magnets 28 to 30 are arranged along the circumferential direction of the turntable 24. It was set up. The first magnet 28 is formed in a rectangular parallelepiped shape as shown in FIG. The first magnet 28 has a length L of 15 to 12
00 mm, width W 5 to 300 mm, height H 10 to 50
The range is 0 mm. The first magnet 28 is hard chrome treated or double nickel chrome treated. The second magnet 29 is formed in a narrow U-shape as shown in FIG. The second magnet 29 is formed by joining L-shaped magnets 29a and 29b together.
The length L1 of a and 29b is 36 to 700 mm, and the total length L2 is 72 to 1400 mm. Moreover, the width W1 is set to 10 to 20.
0 mm, width W2 10-200 mm, height H1 10-
The height H2 is 200 mm, and the height H2 is 15 to 350 mm. The third magnet 30 is formed in a thin plate substantially trapezoidal shape as shown in FIG. 7. This third magnet 30 has a length L3 of 3
0 to 1250 mm, width W3 is 30 to 350 mm, width W4
Is 10 to 200 mm and the height H2 is 3 to 200 mm. Therefore, the length of the first magnet 28 is less than the length L of the second magnet 2.
The total length L2 of 9 is large.

The magnets 28, 29 and 30 are attached to the rotary disk 2
When fixing to 4, arrange 3 pieces in numerical order to make one set,
Fifteen sets are fixed by adhesion and screws so that 15 sets are arranged in a row in the circumferential direction of the turntable 24. At this time, each side surface of the first magnet 28 is joined to each other side surface of the third magnet 30, and the third magnet 3
0 and the first magnet 28 are arranged adjacent to each other in the circumferential direction. And
The inner side surface of the second magnet 29 is joined to the outer side surface of the third magnet 30 near one side. Further, a part of the first magnet 28 projects from the outer peripheral surface 24 a and the one side surface 24 b of the turntable 24, and both ends of the second magnet 29 are the turntable 24.
So that they project from the inner side and the outer side in the radial direction. Then, as shown in FIG. 2, the rotating-side magnet group 26 has an arrangement in which the first magnets 28 of each set are arranged side by side on a line C extending from the center of the stationary plate 25 in the radial direction.
In this state, a mounting screw is inserted into a screw insertion hole formed in the main body of the turntable 24, and screwed into the screw hole of each magnet to firmly fix them. By doing so, the rotation side magnet group 26 can obtain a strong repulsive force by the magnetic force between the rotation side magnet group 26 and the fixed side magnet group 27 without blocking the magnetic force lines emitted from the N pole toward the S pole. .

The stationary magnet group 27 also uses first, second and third magnets 28, 29 and 30 having the same shape as the rotating magnet group 26 shown in FIGS. In this example, three sets of these magnets, one set in the order of numbers, are arranged in a row along the circumferential direction of the fixed plate 25 by adhesion and screwing. In this case as well, a part of the first magnet 28 is projected from each of the outer peripheral surface 25a and the one side surface 25b of the stationary plate 25, and the second magnet 2
Both ends of 9 are projected from the inner side and the outer side of the fixed plate 25 in the radial direction. In addition, this fixed side magnet group 27
As shown in FIG. 3, the first magnets 28 of each set are arranged side by side on a straight line C extending from the center of the stationary plate 25 in the radial direction similarly to the rotation side magnet group 26. Then, the mounting screw is screwed into the screw insertion hole formed in the fixed plate 25,
Moreover, each magnet is firmly fixed by adhering each magnet. As a result, the rotating magnet group 26 and the stationary magnet group 2
In the first and second magnets 28 and 29 that form No. 7, the magnetic poles facing each other between the rotary disk 24 and the fixed disk 25 are the same.
It is an S pole. In this example, the S poles arranged at equal intervals in the circumferential direction face each other in the vertical direction.

A part of each first magnet 28 projects from the outer peripheral surface 24a of the rotary disk 24 and the outer peripheral surface 25a of the fixed disk 25, and the S pole side projects from one side surface 24b, 25b of each disk. . Further, both ends of each second magnet 29 project inward and outward in the radial direction of the rotary plate 24 and the fixed plate 25, so that the S pole side extends longer than the first magnet 28. For this reason, the S poles facing each other between the two boards 24 and 25 and arranged at equal intervals have an uneven shape having a step along the circumferential direction. As a result, both boards 2
The magnetic force lines emitted toward the S pole side from the N poles arranged at equal intervals in 4, 4 respectively generate a density difference in the step portion. Then, when the stationary magnet group 27 is brought close to the rotating magnet group 26, a repulsive force is generated between the S poles, but since there is a density difference in the magnetic force lines, a repulsive force in an oblique direction with respect to the vertical direction acts. . As a result, a strong rotating torque is generated on the turntable 24. Therefore, when the turntable 24 is rotationally driven by some external force, it is rotated by the repulsive force of the magnetic force lines. The fixed-side magnet group 27 has 15 magnets, which is the same number as the rotating-side magnet group 26. However, 16 even-numbered magnets may be arranged in a row along the circumferential direction of the fixed platen 25. In this way, the magnets facing each other will be misaligned, and the lines of magnetic force from the N pole to the S pole will repel each other with a further inclination angle.
At this time, the rotating torque of the turntable 24 further increases.

FIG. 8 is a plan view showing a first modification of the second magnet, and FIG. 9 is a side view showing the first modification. The second magnet 29A is also formed by joining L-shaped magnets 29a and 29b, and the length L1 of each magnet 29a and 29b is 30 to 7.

3 is a clutch control unit, 34 is a starting motor drive unit, 35 is an auxiliary motor drive unit, 36 is an adjustment motor drive unit, 37 is a first cylinder drive unit, and 38 is a second cylinder drive unit.

Reference numeral 39 is a memory in which various data for the control unit 40 to stably maintain and control the rotation speed of the generator 6 are stored in advance. The control unit 40 controls the operation of the magnetic force application rotary device as a whole.
It is unidirectionally or bidirectionally connected to the drive unit and the cylinders 31 to 38, etc. according to each function.

Next, the operation of the magnetic force application rotating device will be described with reference to the drawings. First, when the operator turns on the activation switch of the operation panel 41 provided in the apparatus body 1, the control unit 40 rotationally drives the starting motor 2. At this time, a strong repulsive force acts on both of the rotating side and stationary side magnet groups 26, 27 due to the mutual magnetic force,
The rotating torque on the side of the turntable 24 increases. Next, when the detection signal indicating the predetermined rotation speed is sent from the starter motor rotation sensor 31, the control unit 40 receives the clutch control unit 40.
And the clutch 3 is engaged and disengaged.

Further, the rod of the first cylinder 9 is moved forward to bring the first pulley 7 into contact with the main spindle pulley 5 so as to interlock them. Along with this, the generator 6 is activated, and its output voltage is output from the external connection terminal. When the rotation speed starts to decrease due to this power generation, a detection signal indicating that the rotation speed of the generator 6 has decreased below a predetermined value is input from the generator rotation sensor 32. Upon receipt of this detection signal, the control unit 40 rotationally drives the auxiliary motor 10 and also moves the second cylinder 14 forward to bring the second pulley 11 into contact with the main spindle pulley 5 to interlock them.

As a result, the generator 6 increases its rotation speed to reach the preset rotation speed. Such rotation control is
Since the first and second cylinders 14 and the auxiliary motor 10 are appropriately driven based on the detection signals from the respective rotation sensors, the rotation speed is always kept stable. Therefore, a constant voltage can be output from the generator 6 via the external output terminal. For this reason, if a storage battery is connected to the external output terminal, a stable voltage is supplied, and efficient storage of electricity is possible.
