DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a rotary apparatus capable of rotating a composite rotor at a high speed with a magnetic force, which is structured by arranging a plurality of ring-shaped rotors concentrically with each other.
BACKGROUND ART
Heretofore, no rotary apparatus is known which can rotate a composite rotor at a high speed, which has a plurality of ring-shaped rotors arranged concentrically with each other.
Therefore, the present invention has the object to provide such a novel rotary apparatus.
DISCLOSURE OF INVENTION
In a first aspect of this invention, a rotary apparatus is provided, which is characterized in that a central rotor is centrally arranged so as to be rotatable; a plurality of ring-shaped rotors are arranged concentrically with said central rotor in a relationship spaced apart from each other so as to be rotatable coaxially with said central rotor about its rotational axis; a group of magnetic poles are disposed on a surface of each rotor on the side facing a surface of the adjacent rotor; a group of the magnetic poles disposed on the surface of each rotor is so arranged as to make each of the magnetic poles equal in polarity to another group of the magnetic poles disposed on the surface of the adjacent rotor; and each magnetic pole of the group of the magnetic poles of each rotor is arranged alternately in the rotational direction with each respective magnetic pole of the another group of the magnetic pole of the adjacent rotor.
For the rotary apparatus in the first aspect of this invention, the driving force for rotation applied to the central rotor is transmitted to the outer adjacent rotor one after another by a magnetic repulsive force which is caused to be produced between the rotor and the adjacent rotor so as to repel against the displacement of the rotor in the circumferential direction of the rotation of the rotor. As a result, all the rotors are caused to rotate integrally with each other.
Once the rotary apparatus starts rotating at a high speed, the speed of the rotor on the outer side becomes unlikely to vary due to the effect of a flywheel, thereby inducing a so-called "return-back" phenomenon, i.e. a phenomenon of causing the force of urging the rotation transmitted from the side of the central rotor to turn at the rotor on the outermost side through the rotors on the inner side and eventually back to the central rotor. This "return-back" phenomenon greatly serves as accelerating the rotational speed of each rotor in an extremely efficient way, thereby achieving an extremely high rotational speed.
Further, the present invention in its second aspect provides a rotary apparatus characterized in that the central rotor is centrally arranged so as to be rotatable; a plurality of ring-shaped rotors are arranged concentrically with the central rotor in a relationship spaced apart from each other so as to be rotatable coaxially with the central rotor about its rotational axis; first and second groups of magnetic poles are disposed on the surface of each rotor on the side facing the surface of the adjacent rotor; the first and second groups of the magnetic poles disposed on the surface of each rotor are so arranged as to make each of the magnetic poles equal in polarity to another first and second groups of the magnetic poles disposed on the surface of the adjacent rotor, respectively; each magnetic pole of the first group of the magnetic poles disposed on the surface of each rotor is arranged alternately in the rotational direction with each respective magnetic pole of the another group of the magnetic poles disposed on the surface of the adjacent rotor; and each magnetic pole of the second group of the magnetic poles disposed on the surface of each rotor is arranged so as to overlap with each magnetic pole of the second group of the magnetic poles disposed on the surface of the adjacent rotor.
This arrangement of the rotary apparatus can rotate each of the rotors smoothly because the magnetic repulsive force acting between the first group of the magn
