The second time, the rotor is driven by the kinetic energy to drive the magnet on the rotor to rotate synchronously, then the magnetic line of the magnet generates magnetic force cutting to the coil on the stator, the coil on the stator generates magnetic field change, and further induced current is generated to generate electricity, and the principle is the electricity generation principle of a disc generator.

Two rotor disks including a first rotor disk 30A and a second rotor disk 30B which are disposed on both sides of the plurality of coil windings 22 with a gap therebetween and whose shaft seats 32 are fixed to the rotary shaft 10 by screws 33 so that the first rotor disk 30A and the second rotor disk 30B rotate in synchronization with the rotary shaft 10, a plurality of magnet blocks including a first magnet block 31a and a second magnet block 31B each having an NS pole, which are disposed around the first rotor disk 30A and the second rotor disk 30B and adjacent to the surface side of the coil windings 22 and have opposite poles to each other and opposite poles to each other, that is, the first magnet block 31a and the second magnet block 31B, the respective adjacent poles are disposed in the manner of NS …, and the respective opposite poles are disposed in the manner of NS < - > SN and NS < - > …, please refer to fig. 3B; in the present embodiment, the number of the output portions 28 is equal to 3, and the output portions 28 are respectively inserted into the housing wall of the stator ring 20, and each winding group is respectively connected in parallel with an output line 29 and respectively penetrates out of the housing wall outer edge from the output portion 28. Two sets of fans 40 respectively assembled outside the first rotor disk 30A and the second rotor disk 30B, the fan 40 having a plurality of blades 41 and a shaft hole 42 at the center thereof, which is sleeved on the outer edge of the shaft seat 32 of the rotor disk and locked by screws 43, so that the fan 40 and the rotating shaft 10 rotate synchronously, thereby reducing the heat generated by the induced current in the plurality of coil windings 22.

Fig. 6A to 6B show the arrangement of the first and second magnet blocks 31a and 31B and the plurality of coil windings 22 on the first and second rotor disks 30A and 30B according to the present invention; taking the first rotor disk 30A as an example, the second rotor disk 30B is also the same in structure; the number of the first magnet pieces 31a is different from the number of the coil windings 22 of the inner ring 20A by one, and the number of the coil windings 22 of the outer ring 20B is a multiple of that of the inner ring 20A, but in the present embodiment, the number of the first magnet pieces 31a is 6(a1, a2 … a6), the number of the coil windings 22 of the outer ring 20B is 10(B1, B2 … B10), and the number of the coil windings 22 of the inner ring 20A is 5(c1, c2 … c 5); therefore, the number of the first magnet pieces 31a differs by one from the number of the coil windings 22 of the inner ring 20A, and the number of the coil windings 22 of the outer ring 20B is 2 times that of the inner ring 20A; furthermore, each coil winding 22 of the inner ring 20A and the adjacent coil winding 22 of the outer ring 20B form a conductor group 20C, as shown in fig. 6C, the coil winding 22 No. C1 of the inner ring 20A and the coil windings 22B 1 and B2 of the outer ring 20B form the same conductor group 20C, since the cross-sectional areas of the three parts B1, B2 and C1 are similar, and the width change at the upper edge and the width change at the lower edge of each part are not large, the effective areas of the respective magnetic fluxes are not different, and the magnetic flux densities at the upper edge and the lower edge of each part of the coil winding 22 are similar, so that the operation process of the first rotor disc 30A forms less resistance and generates a larger amount of induced current.

Further referring to FIGS. 7A-7B, the first rotor blade 30A is illustrated, but the second rotor blade 30B is identical; fig. 7A shows a first three-fold offset in the present invention, in which the number of the first magnet blocks 31a of the first rotor disc 30A is 6, the number of the coil windings 22 of the inner ring 20A is 5, and the number of the first magnet blocks 31a is one more than that of the coil windings 22 of the inner ring 20A; fig. 7B shows a second embodiment of the present invention in which the number of the first magnet blocks 31a of the first rotor disc 30A is 4, the number of the coil windings 22 of the inner ring 20A is 5, and the number of the first magnet blocks 31a is one less than that of the coil windings 22 of the inner ring 20A; in the embodiment, the first rotor disc 30A is driven by the rotating shaft 10 to rotate, so that an induced current and a counter electromotive force are generated between the first magnet block 31a and the coil winding body 22, and the counter electromotive force and the first magnet block 31a form an attractive force and a repulsive force; since the number of the first magnet piece 31a and the inner ring 20B coil 22 differs by 1 (one more in fig. 7A and one less in fig. 7B), the first magnet piece 31a and the inner ring 20B coil 22 are misaligned; in addition, since the same conductor group 20C contains 3 coil windings 22 including the inner and outer rings 20A/20B, the first magnet piece 31a is displaced from the same conductor group 20C by three times; for example, the first magnet block 31a of the number a1 passes through the conductor group 20C of the number d1 due to rotation, and the coil winding body 22 of the numbers B1, B2 and C1 is included, so a triple misalignment phenomenon is formed between the first magnet block 31a of the number a1 and the conductor group 20C of the number d1, and the interaction between the attraction force and the repulsion force tends to be smooth in the misalignment process, so that the first rotor carrier disc 30A and the second rotor carrier disc 30B in the utility model rotate more smoothly, and the magnitude of the induced current and the power generation benefit are increased.

In the present invention, the plurality of coil windings 22 are divided into several groups of winding groups, and each winding group is formed by connecting a lead 23 with the plurality of coil windings 22 end to end; fig. 8 shows a first configuration of winding group, in which all the windings 22 (numbers b1, b2, and C1) in number d1 are connected by a wire 23, so that the windings 22 b1, b2, and C1 in the conductor group 20C of number d1 form the same winding group; since the number of the coil windings 22 of the inner ring 20A is 5 in the present embodiment, and each conductor group 20C is formed by the coil winding 22 in the inner ring 20A and the coil winding 22 of the outer ring 20B adjacent to the coil winding 22, there are 5 conductor groups 20C in the first aspect, and thus 5 winding groups are formed. Fig. 9 shows a second configuration of the winding groups, in which the windings 22(c1, c2, c3, c4, c5) of the inner coil 20A are connected by one wire 23 to form one winding group, and the windings 22 of the outer coil 20B are connected by another two wires 23 at intervals, i.e., one set of B1, B3, B5, B7, B9, and one set of B2, B4, B6, B8, B10, so as to form another two winding groups, and thus there are 3 winding groups in the second configuration.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
