Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is an epoch-making method that makes it possible to extract a predetermined rotational torque from the rotor shaft without consuming external energy such as electrical energy. Regarding magnetic motors.

<Conventional Examples and Points of Interchange> In general, when conventional diamagnetic materials are placed in an external magnetic field, they are magnetized to the pole close to the 6ii bar (!-I or the same name, and to the far side or the pole of the different name). Since the degree of magnetization is extremely small, the repulsive force can hardly be used as kinetic energy.

Therefore, motors that use magnetic force have conventionally used soft ferromagnetic materials such as iron, cobalt,
It is possible to use metals or alloys such as nickel as the iron core for the stationary hand and/or the rotor, electrically alternating the poles, and use its strong magnetic attraction and repulsion to achieve rotational movement. It is considered the only practical way to convert. As such motors, induction motors, synchronous motors, DC motors, etc. are known.

However, the above-mentioned ferromagnetic material core has alternating! ffpj
In order to generate A, it is assumed that power consumption is proportional to the motor output. Moreover, there is a limit to the improvement of the material to avoid hysteresis loss, that is, iron loss due to the coercive force of the iron core material, and therefore it is not possible to convert electric power into rotational motion 100% effectively.

Means for Solving the Problems The present invention was proposed to eliminate the drawbacks of conventional motors that utilize the magnetizing force of ferromagnetic materials, and an object of the present invention is to reduce power consumption. Our goal is to provide motors that are not required.

Another object of the present invention is to provide a motor that can initially start and rotate the rotor from the outside and then maintain its rotational output without requiring any external energy supply.

Therefore, the object of the present invention is to provide a magnetic motor consisting of a stationary member made of a permanent magnet and a rotor made of a diamagnetic material made of an amorphous alloy with high magnetic permeability and minimal coercive force. achieved.

<Example> Next, the present invention will be explained in more detail according to an example shown in the drawings.

), iron (Fe), nickel (Ni), molybdenum (MO
), boron, and silicon (Si) are made amorphous, that is, non-crystalline, to change the magnetization characteristics to a diamagnetic material, while maintaining high magnetic permeability and low coercive force. It is.

Now, for the first time, when the rotor (3) is in the state shown in Figure 7gZa, that is, when both ends (P) and (Q) of the long sleeve are located near the center of the magnetic field by the stator (2), it is magnetically neutral and both ends are (P) and (Q) are not magnetized.

Next, when a rotation starting force is applied to the stator (2) in the direction of the arrow (f), the end (P) approaches the fixed magnetic pole S of the stator (2), so as a characteristic of diamagnetic material, it gradually becomes the S pole. magnetized, one end (0) is circumferential 1. fiiN, it is gradually magnetized to the north pole as a characteristic of diamagnetic material, and reaches the magnetic axis (X) of the stator (2) in Fig. 2b, where it receives the maximum magnetizing force, but due to inertial rotation due to external motive force. It still rotates due to the force, and both ends (P) and (Q) correspond! When the stator (2), which faces the &fi poles of the rotor (3) with the same polarity, receives a strong repulsive force, it is urged to rotate in the direction of the arrow in the figure.

Next, when the stator (2) rotates with residual magnetic flux to the position shown in Figure 2c, the end (P) of the S pole receives an attractive force from the N pole of the rotor (3), and the N pole end (P) receives an attractive force from the N pole of the rotor (3). Since the end (Q) of the rotor (3) receives an attractive force from the S pole of the rotor (3), it is further urged to rotate and speed up. After that, when both ends (P) and (Q) come close to the magnetic poles of the rotor (3), their polarities quickly switch, and they end up facing the rotor (3) with the same polarity as shown in Figure 1. , the inertia force caused by the rotational biasing force up to that point crosses the @ axis of the rotor (3), and a repulsive rotational force is applied as described above.

In the above rotation cycle, the stator (2) is made of a material with high saturation, high speed Mi, and small coercive force, so strong repulsive and attractive forces are generated and the rotor shaft (4) is
), and a quick polarity change is possible due to the slight demagnetizing force from the stator (2). Therefore, although the rotor (3) exhibits some pulsating rotation, it continuously rotates while maintaining the rotational speed and rotational torque according to the magnetic flux density, that is, the magnetizing force, of the stator (2).

In the embodiment of the drawings, the stator (2) is shown as having 24 JU, but the stator (2) may have a plurality of 24 JU, and/or the rotor (3) may have two or more salient pole rotors. ,
Further, it is an embodiment included in the present invention to attach a springboard to the rotor I catch (4) to smoothen the rotation.

Effect> According to the magnet motor of the present invention, since a diamagnetic soft material having the characteristics of high saturation magnetic flux density, high magnetic permeability, and small coercive force is used as the material of the rotor, it is possible to Simply by starting the rotor and rotating it, the rotor can rotate continuously and output a predetermined rotational torque without requiring the supply of external energy such as electric power.
