Description

Generator {Generator}

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.

The winding portion 3 and the permanent magnet 7 may be arranged to face each other.

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.

The partition member 34 may be disposed at a position where the spaces between the plurality of magnet members 33 are equally divided. That is, the distance L1 between the partition member 34 and the first magnet member 33a and the distance L2 between the magnet member 34 and the second magnet member 33b may have the same value.

[ 5, the internal magnetic flux FI is generated between one magnet member 33 and the partition member 34, and between the other magnet member 33 and the partition member 34 As shown in FIG.

The external magnetic flux (FO) is understood as a magnetic flux directly acting on the other magnet member (33) in the one magnet member (33).

As a result, the external magnetic flux FO can be weakened as compared with the prior art when the partition member 34 is not disposed. When the external magnetic flux FO is weakened, electrons and holes are easily drawn out in the direction of the conductor 25 even when the rotor 30 performs a low-speed movement, and interaction between the conductor and the electrons (or holes) So that the efficiency of the generator is improved. If the external magnetic flux (FO) becomes too strong, the armature becomes difficult to break the magnetic flux, and the power generation efficiency may be lowered.
