<Configuration Common to Examples 1 and 2>
As shown in FIGS. 1, 3, 10, 11, and 16, the magnetically driven blower or the generator according to the present invention includes a support member 22 and a rotating shaft in a space defined by a frame 21 as a basic structure. A rotating base 1 rotatably supported via 23, and a plurality of rotating fins 2 extending radially from the rotating base 1, that is, from the center of rotation and having an inclination angle θ with respect to the rotation direction; The permanent magnets 3 are individually carried on the rotary fins 2 or, as shown in FIG. 5, the magnetized portions 4 are individually provided on the rotary fins 2 and the permanent magnets 3 of the rotary fins 2 or The core coil 5 is fixedly disposed on the short frame 21 a provided on the frame 21 along the rotation path of the magnetized portion 4, and a rotational force is applied to the rotating fins 2 to blow or / and generate electricity. ing. In the figure, O represents the rotation center of the rotary fin 2, the permanent magnet 3, or the magnetized portion 4.

In the present invention, if the rotary base 1 can be rotatably supported, the rotary shaft 23 can be arbitrarily set as a rotary boss depending on the implementation. In addition, the description that the rotating fins 2 extend in a radial manner is that when two rotating fins 2 are provided with an interval of 180 degrees, when three rotating fins 2 are provided with an interval of 120 degrees, This includes a case where a small number of rotating fins 2 are provided, such as when the rotating fins 2 are provided at intervals of 90 degrees.

As a structure for applying a rotational force to the rotary fin 2 by a magnetic action, the core includes an AC power supply 24 or a battery 7 shown in FIG. 13 and is magnetized by energizing the coil 6 of the core coil 5 from the power supply 24 or the battery 7. The magnetic repulsion between 5 ′ and the permanent magnet 3 or magnetized portion 4 of the rotary fin 2, and the permanent magnet 3 or magnet of the core 5 ′ and the rotary fin 2 that are not magnetized due to the non-energization of the coil 6 of the core coil 5. It has a structure in which a rotational force (rotational force in the X direction in the figure) is applied to the permanent magnet 3 or the magnetized portion 4 by the magnetic attraction action between the magnetic portions 4 and the rotational force is applied to the rotary fin 2. Then, the rotation of the rotating fins 2 blows air (in the Y direction in the figure) or / and generates power, and the power generated by the power generation is stored in the battery 7.

Alternatively, when only power generation is performed, air, steam, water, or the like that moves along the axial direction (Y ′ direction in the drawing) of the rotating shaft 23 is used as a structure that applies rotational force to the rotating fin 2 by fluid pressure. A rotational force (rotational force in the X ′ direction in the figure) is applied to the rotary fin 2 with the fluid pressure of the fluid, power is generated by the rotation of the rotary fin 2, and the electric power generated by the power generation is stored in the battery 7. . The power is stored in the battery 7 through the control circuit 11 and the switching circuit 25.

The permanent magnets 3 have the same orientation of the polarity of all the permanent magnets 3 and are arranged symmetrically with respect to the rotation center O. Similarly, the magnetized portion 4 has the same polarity direction of all the magnetized portions 4. Oriented and arranged symmetrically with respect to the rotation center O, the permanent magnet 3 or the magnetized portion 4 is made to face a core 5 'of a core coil 5 described later.

Preferably, the permanent magnet 3 or the magnetized portion 4 is disposed at the free end 2a of the rotary fin 2, and the rotational force applied to the permanent magnet 3 or the magnetized portion 4 is efficiently transmitted to the rotary fin 2. At the same time, the moment of inertia of the rotary fin 2 is increased.

As shown in FIG. 7, the core coil 5 is formed by winding a coil 6 around a square block-shaped core 5 'made of an electromagnetic steel plate or the like, and as shown in FIGS. The magnets 3 or the magnetized portions 4 are arranged at intervals in the circumferential direction along the rotation trajectory, preferably symmetrically arranged with respect to the rotation center O, and stable magnetism between the permanent magnets 3 or the magnetized portions 4. Cause action (magnetic repulsion and magnetic adsorption). All the coils 6 of the core coil 5 have the same winding direction.

The rotary fin 2 has a free end portion 2a of the rotary fin 2 formed with a terminal surface 2c perpendicular to the radial direction of the rotary fin 2, and a corner portion 2b formed on the terminal surface 2c. The rotary fin 2 can be rotated by the chamfered portion 2b while the core coil 5 and the permanent magnet 3 or the magnetized portion 4 are closely opposed to each other while avoiding contact with the core coil 5. Preferably, the chamfered portion 2b is formed along an arcuate line having a radius from the rotation center O to the center 2c ′ of the end face 2c, that is, the length L shown in FIG.

Further, as shown in FIGS. 2 and 8, a gear plate 8 that rotates integrally with the rotary shaft 23 is provided on the rotary shaft 23, and a single origin detection sensor 9 is provided along the rotation path of the teeth 8a of the gear plate 8. A plurality of teeth number detection sensors 10 are fixedly arranged. The starting point detection sensor 9 is a device that detects passage of the starting point tab 8b of the gear plate 8, and the tooth number detection sensor 10 detects the number of teeth 8a of the gear plate 8 that passes through the tooth number detection sensor 10. The rotation angle of the rotary fin 2, the permanent magnet 3, or the magnetized portion 4 is detected by both 9 and 10. That is, the embodiment illustrates the case where the above-mentioned starting point detection sensor 9 and the number of teeth detection sensor 10 are used as the rotation angle detection sensor. In the present invention, as the gear plate 8, a rotation angle detection rotating disk in which teeth, holes, slits, or protrusions are arranged at equal pitches on the periphery of the disk is used, and the rotation angle detection rotating disk is used as the rotation shaft. 23 and the rotation fin 2 are included.

As shown in FIG. 13, a control circuit 11 is provided for controlling energization and de-energization of the coil 6 of the core coil 5 based on rotation angle detection signals from the starting point detection sensor 9 and the tooth number detection sensor 10. The energization / non-energization control 11 causes the magnetic repulsion action and the magnetic attraction action to apply a rotational force to the permanent magnet 3 or the magnetized portion 4 and to apply a rotational force to the rotary fin 2. Electric power is generated in the coil 6 around which the core 5 'is wound.

As shown in FIGS. 8 and 9, the tooth number detection sensor 10 is arranged by shifting the plurality of tooth number detection sensors 10 by an arbitrary angle instead of at regular intervals. For example, in FIG. 9, four tooth number detection sensors 10 (10A, 10B, 10C, 10D) for detecting the number of teeth for four degrees are prepared, and the interval between the tooth number detection sensor 10A and the tooth number detection sensor 10B is as follows. It is set to (4n + 1) degrees, that is, an angle obtained by adding a 1/4 shift of 4 degrees to a multiple of 4 degrees. Similarly, the interval between the number-of-teeth detection sensor 10B and the number-of-teeth detection sensor 10C is (4n + 2), that is, an angle obtained by adding a 2/4 deviation of 4 degrees to a multiple of 4 degrees, and the detection of the number of teeth 10C and the number of teeth The distance from the sensor 10D is (4n + 3) degrees, that is, an angle obtained by adding a 3/4 shift of 4 degrees to a multiple of 4 degrees.

As described above, by disposing the plurality of tooth number detection sensors 10 at different intervals, the rotation angle can be read more precisely and accurately, and the number of teeth of the gear plate 8 can be reduced. The gear plate 8 can be reduced in size.

Further, as shown in FIG. 14, a plurality of (for example, four) core coils 5 are arranged at equal intervals in the circumferential direction, and the group of core coils 5 is divided into a plurality of groups (in the example shown, two groups... One group). The coil 6 of the core coil 5 belonging to the first group (the coil 6 of the two core coils 5A) is energized through the line 12A. Similarly, the coil 6 of the core coil 5 belonging to the second group (the coil 6 of the two core coils 5B) is energized via the line 12B. Intermittent energization is performed so that energization through the

lines

12A and 12B does not overlap each other.

In other words, the core coils 5A and 5B having different energization systems are alternately arranged along the circumferential direction, the first group of core coils 5A is energized via the line 12A, and the second group of core coils 5B is energized. The configuration is performed via the line 12B.

Power is supplied from the power supply 24 or the battery 7 to the

lines

12A and 12B. The switch element 11a of the control circuit 11 is supplied by a rotation angle detection signal from the starting point detection sensor 9 and the tooth number detection sensor 10 (10A, 10B, 10C, 10D). , 11b, and feeds power to the

lines

The

switch elements

11a and 11b are for ON / OFF control of the supply voltage. The pulse period modulation method in which the pulse ON time is fixed and the period (frequency) is variable, or the pulse period (frequency) is fixed and the ON time is fixed. By the pulse width modulation method that varies the voltage, the voltage can be varied and the rotation speed of the rotary fin 2 can be changed (controlled).

The width dimensions in the rotation direction of all the permanent magnets 3 or all the magnetized portions 4 are made the same, and these are arranged individually on the rotation fins 2 and symmetrically about the rotation center O. Further, the width dimensions of all the core coils 5 in the rotation direction of the permanent magnet are made the same, and these are arranged symmetrically with respect to the rotation center O.

As shown in FIGS. 1, 2, and 6, the permanent magnet 3 according to the first embodiment is formed of a square block magnet and is bonded or screwed to the front side or back side of the free end 2a of the rotary fin 2. The permanent magnet 3 is individually held on the rotating fin 2 while being fixed, and the side surface, that is, the outer surface of the permanent magnet 3 facing the core coil 5 is arranged so as to be perpendicular to the radial direction of the rotating fin 2. Let it be a working surface 3a.

Alternatively, as shown in FIGS. 4A and 4B, the permanent magnet 3 is formed of a plate-shaped magnet, embedded in the free end portion 2a of the rotary fin 2, and supported by the rotary fin 2. The exposed surface facing the core coil 5 is flush with the end surface 2c of the free end 2a to form a magnetic action surface 3a.

Further, as shown in FIG. 4C, a pair of permanent magnets 3 is embedded in the free end 2a of the rotary fin 2, and the exposed surface of one permanent magnet 3 is used as a magnetic acting surface 3a to expose the other permanent magnet 3. The surface may be a magnetic action surface 3b, and the magnetic action surfaces 3a and 3b may be opposite to each other. In this case, a pair of core coils 5 are used, the magnetic action surface 5a of one core coil 5 is made to face the magnetic action surface 3a of the one permanent magnet 3, and the magnetic action surface 5b of the other core coil 5 is The permanent magnet 3 is made to face the magnetic action surface 3b, and the control circuit 11 controls the energization of the coil 6 of the pair of core coils 5 so that the magnetic action surface 5a is interposed between the magnetic action surface 3a and the magnetic action surface 3a. A magnetic repulsion action or a magnetic adsorption action is caused between 5b and the magnetic action surface 3b, respectively.

Alternatively, as shown in FIG. 5, a part or all of the rotary fin 2 is magnetized, that is, the rotary fin 2 is formed of a magnetic member, and an external magnetic field is applied to form a magnetized portion 4 to form the free end 2a. The end surface 2c is defined as a magnetic action surface 4a.

As described above, the direction of the polarity of the permanent magnet 3 is the same in all the permanent magnets 3, that is, the magnetic action surfaces 3a (3b) of all the permanent magnets 3 are arranged as the same pole (N pole or S pole). In the embodiment, the permanent magnet 3 is arranged along the inclination angle θ of the rotary fin 2. Similarly, the direction of the polarity of the magnetized portion 4 is the same in all the magnetized portions 4, that is, the magnetic action surface 4 a of all the magnetized portions 4 is arranged as the same pole (N pole or S pole). Are arranged along the inclination angle θ of the rotary fin 2.

As described above, the core coil 5 has the coil 6 wound around the peripheral surface of the square block-shaped core 5 ′, and both side surfaces of the core 5 ′ facing each other in parallel are exposed from both winding ends of the coil 6; One of the two side surfaces is opposed to the magnetic action surface 3a (3b) of the permanent magnet 3 or the magnetic action surface 4a of the magnetized portion 4 as a magnetic action surface 5a (5b).

In the present embodiment, as shown in FIG. 16A, the permanent magnet 3 or the magnetized portion 4 is disposed on R1 with the rotation center O as the center, and the core coil 5 is concentric with the R1. And it arrange | positions on R2 slightly larger diameter than said R1. The R1 and R2 are arranged on the same level surface, and the permanent magnet 3 or the magnetized portion 4 rotates on the R1 while repeatedly approaching and separating from the core coil 5 on the R2.

As shown in FIG. 6, the magnetic action surface 3a of the permanent magnet 3 does not completely overlap and oppose the magnetic action surface 5a of the core coil 5 due to the inclination angle θ of the rotary fin 2, and the permanent magnet travel (rotation) direction. The facing area on the side is small, the facing area on the side opposite to the permanent magnet travel (rotation) direction is increased, and the rotational force can be efficiently applied to the permanent magnet 3.

More specifically, as shown in FIG. 6C, the magnetic action surface 3 a of the permanent magnet 3 does not face the magnetic action surface 5 a of the core coil 5 on the rotational direction (X direction in the drawing) side of the permanent magnet 3. Whereas there are many portions, on the side opposite to the rotation direction of the permanent magnet 3 (X ′ direction in the figure), the magnetic action surface 3 a of the permanent magnet 3 has more portions facing the magnetic action surface 5 a of the core coil 5. Yes.

Therefore, the magnetic repulsive action that occurs between the magnetic action surface 3a of the permanent magnet 3 and the magnetic action surface 5a of the core coil 5 is largely on the side opposite to the rotation direction (X ′ direction in the figure) and on the rotation direction (X direction in the figure) side. The permanent magnet 3 is naturally given a rotational force in the rotational direction, that is, in the X direction in the figure by the magnetic repulsive action, and blows in the Y direction in the figure. Power generation will be induced. In particular, when the initial rotational force is applied from the stationary state of the rotary fin 2, the rotational force can be effectively applied.

When only power generation is performed, the rotary fin 2 rotates in the X 'direction in the figure due to the fluid pressure of the fluid moving in the Y' direction in the figure, and the non-energized core coil 5 and the rotating permanent magnet 3 generate power. Induces. 6 is the same in principle when the permanent magnet 3 is embedded and carried in the rotary fin 2 and when the magnetized portion 4 is formed on the rotary fin 2, the description thereof will be omitted. .

Here, based on the said Example 1, the operation | movement which provides a rotational force by a magnetic action with FIG. 15 is demonstrated. For convenience of explanation of the operation, the permanent magnet 3 has a permanent magnet 3A, a permanent magnet 3B, and a permanent magnet 3C arranged in order in the traveling (rotating) direction, and the

permanent magnets

3A, 3B, and 3C are positioned as shown in FIG. It is assumed that it is stationary.

In the stationary state of the rotary fin 2, the coils 6 of all the core coils 5 (5A, 5B) are in a non-energized state, and are caused by a magnetic adsorption action between the permanent magnet 3A and the core coil 5A facing the permanent magnet 3A. All the rotation fins 2 are stationary.

That is, in the example shown in the drawing, the magnetic attraction attracting each other between the magnetic action surface 5a of the core 5 'that is not magnetized by the non-energization in the two core coils 5A and the magnetic action surface 3a of the permanent magnet 3A adjacent to the core coil 5A. The action is generated, and all the rotating fins 2 are stationary due to the magnetic adsorption action.

When the start switch S is turned on in the stationary state of the rotary fin 2, the starting point detection sensor 9 and the tooth number detection sensor 10 (10A, 10B, 10C, 10D) transmit a rotation angle detection signal to the control circuit 11. The control circuit 11 detects the position of the permanent magnet 3A from the rotation angle detection signal, and energizes the coils 6 of the two core coils 5A of the first group via the switch element 11a and the line 12A. ), The magnetic repulsion action between the magnetic action surface 5a of the core 5 'of the core coil 5A magnetized by the energization and the magnetic action surface 3a of the permanent magnet 3A opposed thereto, ie, the permanent magnet 3A is shown in FIG. An action of biasing in the direction is generated, an initial rotational force is applied to the permanent magnet 3A, and an initial rotational force is applied to the rotary fin 2, and the rotary fin 2 moves in the X direction in the figure. To start the rotation.

When the rotating fin 2 starts to rotate, as indicated by a dotted line in FIG. 15A, the permanent magnet 3B approaches the core coil 5B, and the magnetic working surface of the core 5 'that is not magnetized by the non-energization in the core coil 5B. 5a and a magnetic acting surface 3a of the rotating permanent magnet 3B, a magnetic attracting action, that is, an action of urging the permanent magnet 3B in the Z 'direction in the figure is generated, and the permanent magnet 3B is rotated by the magnetic attracting action. A force is applied and the rotational force is also applied to the rotating fins 2.

Next, the starting point detection sensor 9 and the tooth number detection sensor 10 (10A, 10B, 10C, 10D) transmit a rotation angle detection signal to the control circuit 11, and the control circuit 11 detects the position of the permanent magnet 3B from the rotation angle detection signal. And the two core coils 5B of the second group are energized through the switch element 11b and the line 12B, and as shown in FIG. 15B, the magnetism of the core 5 'magnetized by the energization in the core coil 5B. A magnetic repulsion action, that is, an action of urging the permanent magnet 3B in the Z direction in the figure is generated between the action face 5a and the magnetic action face 3a of the permanent magnet 3B opposite to the action face 5a, and a rotational force is applied to the permanent magnet 3B. Further, a rotational force is applied to the rotary fin 2 and the rotation of the rotary fin 2 in the X direction in the figure is continued. At this time, as shown in FIG. 15D, the coil 6 of the core coil 5A is not energized.

Subsequently, as indicated by a dotted line in FIG. 15B, the permanent magnet 3C approaches the core coil 5A, and the magnetic acting surface 5a of the core 5 'that is not magnetized by deenergization in the core coil 5A and the rotating permanent A magnetic attraction action, that is, an action for urging the permanent magnet 3C in the Z 'direction in the figure is generated between the magnetic action surfaces 3a of the magnet 3C, and the permanent magnet 3C is given a rotational force by the magnetic attraction action, and the rotational force Is also applied to the rotating fins 2.

Next, the starting point detection sensor 9 and the tooth number detection sensor 10 (10A, 10B, 10C, 10D) transmit a rotation angle detection signal to the control circuit 11, and the control circuit 11 detects the position of the permanent magnet 3C from the rotation angle detection signal. The two core coils 5A of the first group are energized through the switch element 11a and the electric wire 12A, and as shown in FIG. 15C, the magnetism of the core 5 'magnetized by the energization in the core coil 5A. A magnetic repulsion action, that is, an action of urging the permanent magnet 3C in the Z direction in the figure is generated between the action face 5a and the magnetic action face 3a of the permanent magnet 3C opposite to the action face 5a, and a rotational force is applied to the permanent magnet 3C. Further, a rotational force is applied to the rotary fin 2 and the rotation of the rotary fin 2 in the X direction in the figure is continued. At this time, as shown in FIG. 15D, the coil 6 of the core coil 5B is not energized.

Subsequently, as indicated by a dotted line in FIG. 15C, the permanent magnet 3A approaches the core coil 5B, and the magnetic working surface 5a of the core 5 'that is not magnetized by the non-energization in the core coil 5B and the rotating permanent magnet. A magnetic attraction action, that is, an action for urging the permanent magnet 3A in the Z 'direction in the figure is caused between the magnetic action surfaces 3a of the magnet 3A, and the permanent magnet 3A is given a stable rotational force by the magnetic attraction action. .

Then, the starting point detection sensor 9 and the tooth number detection sensor 10 (10A, 10B, 10C, 10D) detect the position of the permanent magnet 3A from the rotation angle, and repeat the same control as the series of energization and deenergization controls. Thus, the rotation of the rotary fin 2 in the X direction in the figure is continued.

As described above, in the magnetically driven blower or the generator according to the present invention, it is not necessary to energize all the core coils 5 (5A, 5B) constantly by energization and de-energization control by the control circuit 11, thereby saving power. Can be achieved.

In particular, the core coil 5 is divided into two groups of

core coils

5A and 5B, and the control circuit 11 simultaneously controls energization and de-energization of the core coils 5A and 5B belonging to each group to efficiently generate the magnetic repulsion action and the magnetic adsorption action. A stable rotational force can be applied to the rotary fin 2.

The explanation of the operation by the magnetic action described the rotation action from the stationary state by the magnetic attraction action between the permanent magnet 3A and the core coil 5A, but between the permanent magnet 3A and the core coil 5B, or between the permanent magnet 3B or the permanent magnet 3C and the core coil 5A or The operation principle is the same even from a stationary state due to the magnetic attraction between the core coils 5B. Although the operation was explained using the permanent magnet 3, the principle of operation is the same for the magnetized portion 4, so that the explanation is omitted here.

Further, in the explanation of the operation by the magnetic action, for the non-energized core coil 5 (5A, 5B), the permanent magnet 3 (3A, 3B, 3C) rotates and the magnetic flux generated from the permanent magnet 3 is changed to the coil 6 of the core coil 5.
