Abstract

PURPOSE:To obtain a driving force directly from heat and to generate a high torque by composing a prime mover of a rotor to which a superconductor is secured, a magnet and a heat source. CONSTITUTION:A prime mover is composed of a columnar rotor 1 employed at its center as a rotary shaft, superconductors 2a-2d so secured to the surface of the side of the rotor 1 as to be symmetrical with respect to the rotary shaft, magnets 3a-3b for applying a magnetic field to the superconductors, a hot heat source 4 for heating the superconductors 2a-2d to a transition temperature or higher, and a cold heat source 5 for cooling to a transition temperature or lower. W hen the superconductors 2a-2d are cooled to the transition temperature or lower, Meissner effect is generated, only the superconductor 2 near the magnets 3a-3b is cooled to the transition temperature or lower, thereby obtaining a driving force. Thus, since a torque generated at this time is also generated at the time of stopping, a high torque is obtained at a low speed rotation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a prime mover that requires high torque at low rotation speeds.

Conventional technology motors include DC motors, AC motors, and AC motors that use electricity.
There are engines that use pistons, such as gasoline engines and steam engines, and engines that use turbines. These prime movers require high speed.

Items that require high torque, items that require small size, etc.
There are various types depending on the purpose of use.

Problems to be Solved by the Invention However, the above-mentioned prime movers use heat directly as energy, and there have been no small-sized, high-torque ones.

In view of the above problems, it is an object of the present invention to provide a compact, high-torque prime mover with a simple configuration, which obtains power by cooling a superconductor to which a magnetic field is applied and making it completely diamagnetic.

Means for Solving the Problems In order to achieve this object, the prime mover of the present invention includes a rotor with a cylindrical center as the rotation axis, and a rotor with a rotor on the side surface of the rotor so as to be symmetrical with the rotation axis of the rotor. A plurality of fixed superconductors, a magnet that applies a magnetic field to some of the superconductors, a cold source that cools the superconductor to which the magnetic field is applied by the magnet to below the transition temperature Tc, and some other superconductors It is characterized by comprising a heat source that heats the temperature to a transition temperature of 10 or more.

Effect The effect of the present invention is that when a superconductor is cooled below the transition temperature Tc, it exhibits complete diamagnetic properties, the magnetic field inside the superconductor is always zero, and the superconductor is magnetized in a direction that cancels out the external magnetic field. This is achieved by using the so-called Meissner effect to obtain driving force by lowering only the superconductor near the magnet to a temperature below the transition temperature.

That is, superconductors are arranged symmetrically with respect to the rotation axis, a magnetic field is applied to some of the superconductors by a magnet, and the transition temperature T is reached by a cold source. Cool to below. Then, a magnetic field is applied to the superconductor, which has been cooled to below the transition temperature -Tc, so that the superconductor moves in the direction in which the magnetic field applied to the superconductor becomes smaller, and this force causes rotational torque to increase. occurs, causing the rotor to rotate and act as a prime mover. The torque generated at this time is also generated when the engine is stationary, so it becomes a prime mover that can obtain high torque at low rotation speeds.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a cylindrical rotor with its rotation axis at the center, 22L to 2d are superconductors fixed to the side surface of the rotor 1 so as to be symmetrical with respect to the rotation axis of the rotor 1, and 3a , 3b is a magnet that applies a magnetic field to the superconductors 22L to 2d, 4 is a heat source for heating the superconductors 2+L to 2d to a transition temperature of 10 or higher, and 5 is a heat source for cooling the superconductors 2a to 2d to below the transition temperature. It is a source of cooling and heat. Although not shown in the figure, a mechanism for obtaining power from the rotation of the rotor 1, magnets 32L, 3b, heat source 4. A structure for fixing the cold source 6 is required.

The operation of this embodiment will be explained using FIG. 2. Figure 2 is a diagram showing the relationship between temperature and resistance of a superconductor, with transition temperature Tc
Below, the resistance becomes 0 and complete diamagnetism is exhibited. Now, set the temperature of heat source 4 to T4. The temperature of the cold heat source 6 is set to T2 (T2<To
<T, ), and the temperature of the superconductor 2& when the rotor 1 is in the position shown in FIG. 1 is T3. The temperature of the superconductor 2b is set to T4.
The temperature of superconductor 2C is T5° The temperature of superconductor 2d is T6
shall be. As shown in FIG. 2, when the temperatures T5 to T4 of the superconductors 2a to 2d have the following relationship, To<T5(T, . . .
...(1) T2<T5<To...(2) To<T4. T6 (T5...
(3) Force f acts in the direction of decreasing the magnetic field only on the superconductor 2c whose temperature is below the transition temperature Tc and to which the magnetic field is applied, causing the rotor 1 to rotate counterclockwise. As the rotor 1 rotates, the temperature T5 of the superconductor 2C exceeds the transition temperature Tc and the force disappears, but at this time, the temperature T6 of the superconductor 2d decreases to 9, which is below the transition temperature, as mentioned above. As shown, the force acts and keeps the rotor 1 rotating. If the position where the temperature of the superconductors 2a to 2d becomes equal to or lower than the transition temperature Tc is in a large area closer to the cold source 5 than the line of symmetry of the magnetic field, the rotation direction of the rotor 1 is uniquely determined. Even if this position is in the region B, if the rotor 1 is rotating in the direction from B to the person (rotation to the left), the specific heat of the superconductors 2a to 2d will keep the rotor 1 at a transition temperature T during the rotation.

The following positions are in the human area9, and the rotation continues Q In Fig. 1, if the functions of the heat source 4 and the cold source 5 are exchanged, the rotation direction of the rotor 1 will be clockwise υ. Further, even if the magnet 3b is placed in a position opposite to the cold source 5, the rotational direction of the rotor 1 is reversed, and the rotational direction of the rotor 1 can be controlled.

Also a cold source 5. Temperature 2 position of heat source 4, magnet 3a,
The rotational speed of the rotor 1 can be controlled by the strength and position of the magnetic field 3b. The magnet 3a is not required if the heat source is not replaced.

Furthermore, when the transition temperature Tc is below room temperature, the heat source 4 is not necessarily required, and when the transition temperature Tc is above room temperature, the cold source 5 is not necessarily required.

In this example, the superconductor is divided into four parts, but
As shown in FIG. 3, the surface of the rotor 1.

Even if it covers the whole thing, it works in the same way.

Effects of the Invention As described above, the prime mover of the present invention has a simple structure consisting of a rotor to which a superconductor is fixed, a magnet, and a heat source, and can obtain driving force directly from heat. Furthermore, since high torque is generated at low speeds, power can be transmitted with a simple configuration without the need for a speed reducer or the like.
