Abstract
Description
An embodiment of the present invention relates to a generator.
The generator is understood as a device that generates electric energy from a coil by driving a coil between the magnetic poles forming the magnetic field or by activating a magnetic pole between the coils. Usually, a unit including a magnetic pole for forming a magnetic field is called a field, and a unit including a coil for generating the electric energy is called an armature.
Such a generator may include a rotary generator in which one of the field and the armature is disposed on the other side of the outer periphery, and a reciprocating generator in which the field and armature are arranged to face each other in the axial direction.
In the rotary type generator, a rotating unit of the field and armature is called a " rotor " and a fixed unit is called a "stator ". For example, a generator in which a field rotates is called a revolving type generator, and a generator in which an armature rotates is called a revolving type generator.
The rotary type generator may be divided into a rotary type generator for rotating the magnetic field of the field inside the fixed armature and a rotary type electric generator for rotating the armature between fixed fields.
1A and 1B, a conventional rotary generator is shown. FIG. 1A is a front view of an internal structure of a conventional generator, and FIG. 1B is a sectional view seen from the side.

In the generator, when the armature breaks the magnetic flux created by the magnetic pole, the voltage is induced in the coil. However, according to such a conventional generator structure, a strong magnetic field is formed between adjacent magnets or electromagnets arranged in the circumferential direction, and the armature becomes difficult to break the magnetic flux, resulting in a problem of low power generation efficiency.
If the gap between the field and the armature is increased in order to reduce the influence of the strong magnetic field as described above, the power generation efficiency may be adversely affected. Therefore, it is preferable that the gap is formed within a set range. However, in order to reduce the clearance, there is a problem that the manufacturing method of the generator becomes complicated and the cost of the generator increases when precision processing is performed.
Also, in order to increase the power generation efficiency, a high-speed rotation or a high-speed reciprocating motion of the rotor is required. However, there is a problem that the cost for manufacturing the generator increases when the design is designed.
The embodiments of the present invention have been proposed in order to solve the above-mentioned problems, and it is an object of the present invention to increase the efficiency of the generator and to reduce the manufacturing cost of the generator.
The generator according to one aspect includes: a stator; A rotor positioned at one side of the stator and having a rotating shaft; A plurality of magnet members disposed circumferentially on the rotor or the stator; A plurality of coil assemblies disposed opposite one side of the plurality of magnet members; And a partition member disposed on the rotor or the stator and disposed between the plurality of magnet members, wherein the partition member has a magnetic flux which acts between the plurality of magnet members, the inner magnetic flux FI and the outer magnetic flux (FO) As shown in FIG.
In addition, the partition member may be disposed at a position bisecting the space between the plurality of magnet members.
Further, the magnet member and the partition member may extend from the center of the rotation axis in the radial direction of the main body.
In addition, the internal magnetic flux (FI) is formed between one magnet member and the partition member among the plurality of magnet members, and between the other magnet member and the partition member, and the external magnetic flux (FO) And a magnetic flux directly acting on the other magnet member in one magnet member.
