Abstract

The present invention relates to a coreless multi-phase bidirectional generator, which can prevent a cogging phenomenon that appears during the rotation of a rotor corresponding to a stator that is formed of a stack of silicon steel plates and increase power generation by rotating the rotor and the stator in directions opposite to each other and, at the same time, by providing a multistage stator design for increasing an enamel dose. That is to say, the present invention relates to a coreless multi-phase bidirectional generator, wherein a coil bundle formed by winding an enamel wire is installed in a slot of a coil casing between permanent magnets that are arranged to have opposite poles facing each other at a preset distance apart, thereby interlinking with flux lines coming from the permanent magnets, and the enamel line wound stator rotates in the opposite direction to the rotation of the rotor attached with the permanent magnets so as to induce a high generating voltage even at a low rotation rate. To this end, windmills having blades of opposite directions are connected, respectively, to the rotor and stator. The enamel line wound stator can be manufactured in a multi-stage (e.g., 2-stage) process along a concentric circle such that power generation may increase.

Description

generator

The present invention relates to a generator, and more particularly, to eliminate cogging phenomena occurring during rotation of a rotor corresponding to a stator to which a laminated silicon steel sheet is applied, and while the rotor and the stator rotate in opposite directions to each other, The present invention relates to a coreless multi-stage two-way generator that can be multi-stage and increase enamel dose to increase power generation.

Motors or generators that rotate using laminated silicon steel coils wound with permanent magnets and enameled wires rotate smoothly due to cogging phenomena that are overwhelmed by the teeth due to the toothed slots formed in the laminated silicon steel sheets and parts that are not. This was difficult.

In addition, at low wind speeds, the rotor's rotational speed was low, and the charging start voltage of the rechargeable battery could not be reached.

Accordingly, the present invention is to provide a generator to remove the cogging phenomenon of the generator, and to increase the amount of power generation of the generator even in weak winds without expansion of the appearance.

In the present invention, to provide a generator that solves the problems described above, the coreless generator provided in the present invention constitutes a stator by winding an enamel wire on a nonmagnetic material is not affected by magnetic force, and the stator is required It can be installed in multiple stages to increase the enamel dose without expansion of the generator's appearance.In contrast to the rotational direction of the rotor, the stator rotates to increase the chain speed of the enamel and magnetic lines, increasing the voltage induced in the enameled wire even at low rotational speeds. It is possible to increase, and to provide a generator consisting of a rotor with permanent magnets facing each other to the left and right of the enameled wire.

Coreless multi-stage two-way generator according to the present invention, there is no core made of silicon steel sheet affected by the magnetic force can eliminate the cogging phenomenon acting as a resistance during rotation.

In addition, the stator is installed inside the generator housing in multiple stages without external expansion, increasing the enameled dose to increase the amount of power generated, and allowing the stator and the rotor to rotate opposite to each other to reach the charging start voltage of the rechargeable battery even at low speed, thus enabling the generator to operate. It is an invention that the expected effect is great, such as efficiency can be improved.

This means that when the rotor 9 rotates, the three

magnet holders

6, 7, and 8 fixed thereto rotate together.

When the

permanent magnets

2, 3, 4 and 5 are attached to the

magnet holders

6, 7 and 8, the

permanent magnets

2, 3 and 4 attached to the

magnet holders

6, 7 and 8 facing each other. , 5) are arranged in different poles.

And the enameled wire coil bundle is inserted into the slot 12 of the coil box (10, 11) and then placed between the permanent magnets (2, 3, 4, 5) facing each other.

Coil bundle is inserted into the slot 12 of the coil box (10,11) but in accordance with the constant. At this time, the coil box (10, 11) is to replace the existing core, consisting of a non-magnetic material is not affected by the magnetic force in order to eliminate the cogging phenomenon, the coil box (10, 11) bound in the circumferential form stator 13 ).

In FIG. 4, the coil bundles are formed by winding an enamel wire in the form of a coil in one

coil box

10 or 11 which is a nonmagnetic material.

coil boxes

10 and 11 forms a recess 14 and a convex part 15 on both sides thereof to be assembled with the neighboring

The

coil boxes

10 and 11 are coupled to the stator 13 to be rotatable together and to be rotated separately from the rotor 9.

In the existing generator, the stator is fixed and only the rotor rotates, but in the present invention, the stator 13 is rotated.

When the stator 13 is rotated in the opposite direction to the rotor 9, the magnetic force lines of the

permanent magnets

2, 3, 4, and 5 cross the speed at which the enamel lines are fastened, and a high generation voltage can be obtained even at a weak wind.

This is to reach a charge start voltage that can charge the battery even in a weak wind early, and the operating efficiency of the generator (1) is maximized.

In order to obtain the above-mentioned effect, as shown in FIG. 5, the

windmills
