DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generator, and more particularly, to a power generating device, in which a plurality of electromagnets are arranged in a ring shape, and a cam-shaped magnetic body is arranged inside the electromagnets arranged in a ring shape. ,
A current is sequentially passed through the side-by-side electromagnets so that a part of the outer peripheral surface of the magnetic body is sequentially attracted by each electromagnet to move the magnetic body, and to impart a rotational motion to the non-ferrous power shaft inserted through the magnetic body. The present invention relates to a power generator that has been developed.

2. Description of the Related Art Conventionally, as a power generating device for obtaining power from electric energy, a rotating electromagnet is rotated by a mutual attractive force of an annular fixed electromagnet and a rotating electromagnet supported at the center thereof, and the rotating force is taken out as power. In addition, there is a so-called electric motor. In such a case, the rotating electromagnet is always attracted to the circular fixed electromagnet outside of the rotating electromagnet at a certain distance. However, since the magnetic force is inversely proportional to the square of the distance, when the magnet attracts an iron piece or the like, the maximum force is immediately before the two come into contact with each other.

[0003]

According to the present invention, the conventional motor has a fixed distance between the rotating electromagnet and the fixed electromagnet outside the rotating electromagnet as described above. And the fact that when the magnet attracts an iron piece or the like, the maximum force is about to be integrated with the two, and is even larger than the conventional motor. Power can be obtained, and in addition, by using the electric energy of the electromagnet and the magnetic energy of the permanent magnet together,
The rotational force can be further increased, and at the moment when the attracting motion occurs between the newly energized electromagnet and the magnetic material, the force relationship due to the intraction with the electromagnet whose energization has been stopped is eliminated, and thus the smoother. Another object of the present invention is to provide a power generating device capable of rotating a magnetic body.

[0004]

According to the present invention, a plurality of electromagnets arranged in a ring and energized one by one and an electromagnet arranged inside the ring-shaped electromagnets are provided. A cam-shaped magnetic body having two raised portions on the side and a step formed at one circumferential end of each raised portion, and a side surface of the magnetic material and one end surface thereof An arc-shaped permanent magnet attached to and aligned with the step portion, and a non-ferrous power shaft inserted through the center of the magnetic body and rotated at the center of the annularly arranged electromagnet via a bearing, whereby When energizing the electromagnet positioned in the rotation direction of the ridge provided on the magnetic body, the magnetic flux between the step of the ridge and the excited electromagnet is the excited electromagnet. It converges within a range that connects the arc-shaped permanent magnet provided facing the step portion almost linearly, and The protruding portion of the magnetic material is attracted and rotated by the excited electromagnet, and then the energization of the exciting electromagnet is performed when the stepped portion of the magnetic material reaches an adjacent electromagnet in the magnetic material rotating direction ahead of the exciting electromagnet. By stopping the magnet and exciting the electromagnet adjacent to the front in the rotation direction of the magnetic body, the magnetic body is attracted by the newly excited electromagnet and continues to rotate, and the newly magnetized electromagnet is rotated. The magnetic body portion facing the non-excited electromagnet located rearward in the rotation direction becomes a blank area of magnetic flux,
Power generation device comprising structure characterized by comprising by applying a rotational torque by the magnetic flux the convergence without receiving a magnetic attraction force against the rotation of the magnetic body in the non-ferrous power shaft
Is the gist .
