Description

  The present invention relates to a magnetic force driving device characterized in that a permanent magnet having a strong magnetic force is attached to a magnetic core end portion of an electromagnet, and a permanent magnet having a strong magnetic force is arranged on the side to generate a driving force.

A conventional permanent magnet type DC motor uses a magnet having a weak magnetic force such as a ferrite magnet as a stator and an electromagnet as a rotor.
In addition, devices that linearly drive with an electromagnet and a magnet, such as a linear motor, often use a combination of a magnet with a weak magnetic force, such as a ferrite magnet, and an electromagnet.

  If a permanent magnet having a strong magnetic force such as a neodymium magnet is used to increase the driving force, the permanent magnet and the magnetic core are adsorbed, making it difficult to obtain a mechanical driving force. In order to obtain driving force in this state, more power is required.

In order to solve this problem, instead of simply attracting and repelling the conventional electromagnet and permanent magnet, an electromagnet core is attached to the side of the permanent magnet with strong magnetic force, and the small magnetic force of the electromagnet It is effective to use the property that a strong driving force is generated in a permanent magnet having another strong magnetic force facing each other when the surrounding magnetic force is distorted. However, in Patent Document 1 which attempts to solve this problem, the magnetic core of the electromagnet is used. It is arranged so that the magnetic field lines between the permanent magnets are interrupted, and in this case, it is easy to use the attractive force of the permanent magnet and the magnetic core as the driving force, but the repulsive force between the rotor magnetic core and the permanent magnet of the stator is It is small and it is difficult to effectively use the repulsive force as the driving force.
Further, as similar to the present invention, in Patent Documents 2 and 3, the coil moves along the magnetic gradient between the permanent magnets, and does not operate the magnetic force between the permanent magnets to generate the attractive repulsion force.

Problems to be solved by the invention

This has the following drawbacks.
A conventional permanent magnet type DC motor has a structure that attracts and repels an electromagnet and a permanent magnet. When rotating, a large amount of electric power was needed to meet the load that attracts and repels the stator, resulting in poor electrical efficiency.
In addition, when trying to increase the motor output, a permanent magnet with a strong magnetic force such as a neodymium magnet must be used for the stator. There was a drawback.
The same applies to devices that are linearly driven by an electromagnet and a magnet, such as a conventional linear motor.
The present invention has been made to eliminate the above drawbacks.

Means for solving the problem

In conventional driving bodies with a combination of electromagnets and permanent magnets, ferrite magnets with low magnetic force are used. However, if permanent magnets with strong magnetic force such as neodymium magnets are used to increase this driving force, the magnetic force is strong. Since the permanent magnet and the magnetic core are attracted, it is difficult to obtain a mechanical driving force.
In order to obtain driving force in this state, more power is required.

Instead of simply attracting and repelling conventional electromagnets and permanent magnets as a means to solve the problem, an electromagnet is attached to one of the strong permanent magnets facing the same pole and the small magnetic force of the electromagnet is strong. When the magnetic force around is distorted, a strong driving force is generated.
The driving direction changes in the direction of the magnetic pole axis of the electromagnet or in the vertical direction depending on whether the permanent magnet without the electromagnet is faced in parallel with the facing permanent magnet or faced at an angle. The driving direction can be controlled by the attitude of the permanent magnets facing each other.
This is because the strong magnetic force between the permanent magnets is operated by the small magnetic force of the electromagnet to generate a strong driving force. This driving force is the same power and larger than the driving force of the conventional ferrite magnet and electromagnet combination. become.

  There are a method for generating a driving force in a direction perpendicular to the magnetic pole axis of the electromagnet and a method for generating the driving force along the magnetic pole axis direction of the electromagnet.

First, as a method of generating a driving force in a direction perpendicular to the magnetic pole axis of the electromagnet, a permanent magnet (3) having a strong magnetic force parallel to the magnetic core (2) at the end of the magnetic core (2) of the electromagnet (1). In addition, a permanent magnet (4) having a strong magnetic force is arranged in parallel so that the same poles face each other.
When the permanent magnets (3), (4) and the electromagnet (1) having strong magnetic forces facing each other have different polarities, there is a method of generating a strong driving force in a direction perpendicular to the magnetic pole axis (FIG. 1).

The principle that the magnetic field around the strong permanent magnet (3) is easily distorted by the electromagnet (1) is that when the magnets attract each other, the magnetic field lines gather from the N pole to the S pole even if the magnetic force of one of them is small (see FIG. 2).
Thereby, when the permanent magnet (3) having a strong magnetic force attracts the electromagnet (1), the magnetic field around the permanent magnet (3) having a strong magnetic force is easily distorted with a small amount of electric power (FIG. 3).
Even in a stationary state due to this action, the same effect as changing the direction of the permanent magnet (3) having a strong magnetic force occurs, and the permanent magnet having a strong magnetic force in the direction perpendicular to the magnetic pole axis of the electromagnet (1) shown in FIG. A driving force is generated in the magnet (4).

  The magnetic core (2) end of the electromagnet (1) is attached to the side of the permanent magnet (3) with strong magnetic force in parallel, and the permanent magnet (4) with strong magnetic force is placed in parallel so that the same poles face each other The electromagnet (1) operates the direction of the magnetic lines of force of the permanent magnet (3) having a strong magnetic force, thereby generating a strong driving force in the direction perpendicular to the magnetic pole axis in the permanent magnet (4) having a strong magnetic force. There is a magnetic drive device characterized.

Next, as a method for generating a driving force along the magnetic pole axis direction of the electromagnet (1), a permanent magnet (3) having a strong magnetic force parallel to the magnetic core (2) at the end of the magnetic core (2) of the electromagnet (1). ), And the permanent magnet (4) having a strong magnetic force is inclined so as to be close to the magnetic core (2) so that the same poles face each other.
When the polarity of the electromagnet (1) is changed, there is a method of generating a strong driving force in the magnetic pole axis direction in the permanent magnet (4) having a strong magnetic force (FIG. 4).

The principle by which the apparatus configured as shown in FIG. 4 generates a strong driving force along the magnetic pole axis direction of the electromagnet (1) will be described using a model.
Permanent magnets (5) and (6) having a flat end and facing each other are made to face each other. In this state, it only repels uniformly (FIG. 5).
Next, the permanent magnets (5) and (6) having a strong magnetic force inclined to each other are made to face each other with the same polarity. Since the magnetic force increases in inverse proportion to the square of the distance, the magnetic force between the magnets draws a curve, and the portion where the magnets are closest to each other has the largest repulsive force (FIG. 6).
While the magnets are closest to each other, the magnetic core (2) of the electromagnet (1) is arranged to make the electromagnet (1) different from the permanent magnets (5) and (6) having a strong magnetic force. The attracting force between the closer permanent magnets (5), (6) and the magnetic core (2) that are closer to each other is larger than the repulsive force between the magnets, and therefore attracts strongly as a whole (FIG. 7).
Next, when the electromagnet (1) has the same polarity as the permanent magnets (5) and (6) having a strong magnetic force, the permanent magnets (5) and (6) having a strong magnetic force and the magnetic core (2) are repelled and the permanent magnet having a strong magnetic force ( 5) Since (6) also repels each other, they strongly repel each other as a whole (FIG. 8).
Even if the electric power is small, the smaller the cross-sectional area of the magnetic core (2) of the electromagnet (1), the larger the magnetic flux density, and the permanent magnets (5) and (6) with strong magnetic force can be easily repelled.

However, since the permanent magnets (5) and (6) with strong magnetic force and the electromagnet (1) are separated into three, it is difficult to use industrially, so the magnetic pole shaft is placed at the end of the magnetic core (2) of the electromagnet (1). A permanent magnet (3) with a strong magnetic force is attached in parallel with (2), and the permanent magnet (4) with a strong magnetic force is tilted so as to be close to the magnetic core (2) side so that the same poles face each other. (FIG. 4).
As a result, a strong driving force is generated in the permanent magnet (4) having a strong magnetic force along the magnetic pole axis direction of the electromagnet (1).

  A permanent magnet (3) having a strong magnetic force is attached to the end of the magnetic core (2) of the electromagnet (1) in parallel to the magnetic core (2), and a permanent magnet (4) having a strong magnetic force so that the same poles face each other. ) Is tilted so as to be close to the magnetic core (2) side, and the electromagnet (1) operates a line of magnetic force to generate a strong repulsive force along the magnetic pole axis direction of the electromagnet (1). There is a magnetic drive device.

The magnetic force generated by the shape and angle of the permanent magnet is affected. If the portion of the permanent magnet (4) having a strong magnetic force indicated by the dotted line is lengthened, the attractive force with the magnetic core (2) is increased, and if the portion is shortened, it is decreased.
Further, when the angle of inclination of the permanent magnet (4) is made shallow, the distance between the permanent magnets (3) and (4) having a strong magnetic force is reduced, so that the repulsive force is increased, and when the angle is made deeper (FIG. 9).
Further, as shown by the dotted line, when the permanent magnet (3) having a strong magnetic force is attached so as to protrude from the end of the magnetic core (2), the repulsive force is increased, and conversely, it is reduced when attached to the back (FIG. 10).

From these conditions, in order to further improve the attractive repulsion force of the magnetic force driving device, it is possible to increase the angle of inclination of the lower side of the permanent magnet (4) having a strong magnetic force and to decrease the angle of inclination of the upper side. In order to realize this, the permanent magnet (7) having a strong curved surface with a concave surface or a concave angular surface is inclined so as to approach the magnetic core (2) side of the electromagnet (1).
This increases the suction repulsive force during driving, leading to an improvement in output (FIG. 11).

  A permanent magnet (7) having a strong curved surface with a concave surface or a concave angular surface is disposed to be inclined toward the magnetic core (2) of the electromagnet (1), and along the magnetic pole axis direction of the electromagnet (1). There is a magnetic drive device characterized in that a strong drive force is generated.

  When the magnetic force driving device is applied to a rotating device, it is more efficiently driven when the opposing ends of the rotor and the stator are curved along the rotation circle.

  When applied to a rotating device, a permanent magnet (10) having a curved magnetic core protruding from the pole portion is attached to the end of the curved magnetic core (9) protruding from the tip of the electromagnet (1), and the same poles are attached to that side. The electromagnet (1) is configured such that the permanent magnet (11) having a curved surface with a concave surface along the rotation circumference is inclined so as to be close to the magnetic core (9) side of the curved surface protruding from the tip. The magnetic force drive device is characterized by generating a strong repulsive force in the rotational direction on the strong permanent magnet (11) having a curved surface whose surface is recessed along the rotation circumference by manipulating the magnetic force lines. There is (FIG. 12).

  Next, a magnetic rotation device, a magnetic arc drive device, a magnetic linear drive device, a magnetic vibration device, and a magnetic speaker using the magnetic drive device will be described.

There is a magnetic force rotation drive device characterized in that rotation is driven by reversing the polarity of the electromagnet (1) in accordance with the rotation position by the brush (13) and the commutator (14) (FIG. 13).

However, it is not considered that the above-described magnetic force rotation driving device simply attaches the electromagnet (1) to the shaft (12) and maximizes the rotational output.
