The front view of the stator 110 will be referred to FIG. 1. The first stator 110-1 and the second stator 110-2 are formed with one or more assembly grooves 115 and are fixed to each other through an assembly member 116 coupled with the assembly groove 115. The assembly member 116 may include an assembly rod and a bolt.

By doing so, it is possible to improve the power generation efficiency.

The first stator 110-1 includes a first protection member 117-1 surrounding the first rotator 120-1 and a second protection member 117-2 surrounding the second rotator 120-2. And, the second stator 110-2 includes a third protection member 117-3 surrounding the third rotator 120-3 and a fourth protection member 117-4 surrounding the fourth rotator 120-4. It includes.

It may have, and may have a number of 12 cores, as shown in Figure 6c, may be composed of a number of cores, but is not limited thereto.

FIG. 7 shows the rotator and magnetic shield of FIG. 2 in detail, and the magnetic shield 130 may be coupled to the rotator 120 in an attaching or assembling manner. The magnetic shield 130 is a magnetic material having a high magnetic permeability, for example, an iron plate, and provides a magnetic shielding function. Magnetic shielding means that when a certain space is enclosed by a magnetic material having a large magnetic permeability, the magnetic flux is focused on the magnetic material, so that the magnetic field is not affected by the magnetic field.

The power generation coil 112 generates electricity through a magnetic field according to the rotation of the rotator 120 to generate AC power.

The atomic nucleus of a material has its own spin, and these spins are distributed in disorder in the material, but when a magnetic field is applied, the spin is oriented, and when an electric field is applied thereto, perturbation occurs. Precession occurs due to perturbation. At this time, when generating an oscillation frequency that matches the natural frequency of the atomic nucleus in the magnetic field, nuclear magnetic resonance (NMR) occurs. Nuclear magnetic resonance refers to a phenomenon in which the electric energy of the oscillation coil 111 acts on the magnetic moment of the atomic nucleus in the magnetic field to absorb the energy and transition to another energy level.

9 is an example of comparing the magnetic flux concentration of the permanent magnet according to the presence or absence of the magnetic shield. When the magnetic shield 130 is present, the magnetic flux of the permanent magnet 121 may be focused as much as the B portion.

The magnetic generator 100 may include a loopback processor 150 that receives and charges a portion of the AC power generated by the power generation coil 112 and provides the charged power to the oscillation coil 111. The loopback processor 150 receives a portion of the AC power generated by the power generation coil 112, converts it into DC, charges it, converts the charged DC into an AC electric field, and applies it to the oscillation coil 111.

The loopback processor 150 may be included in each magnetic generator 100, and may supply power to oscillation coils of a plurality of magnetic generators. For example, the loopback processor 150 may be connected on a one-to-one basis with a magnetic generator, and includes a plurality of capacitors, as shown in FIG. 4, with two magnetic generators 100-1, 100-2 and one-to-two. It can be connected, it can be connected to the N magnetic generator 100 and 1 to N, but is not limited thereto.

The magnetic generator 100 may further include a source supplyer (not shown) that supplies a source for rotation of the rotator 120.

The magnetic generator 100 according to the present invention can be used as an independent power source and can supply the remaining power to an external power system in connection with a transmission system. In order to link the grid, various control technologies such as frequency control as well as reactive power control are required.

In the present invention, the preliminary force is controlled by the closed loop control method on the power transmission 160. In the system, the frequency decreases when the load increases, and when the power generation exceeds the load, the frequency increases. In the present invention, the frequency is controlled using a frequency controller (not shown) with a preliminary force detection function. The preliminary power reduction function refers to a function of reducing power generation with several% (generally 5%) of reserve power for 100% normal operation, and increasing power generation when the load increases.
