Description

The present invention relates to a high-efficiency energy-saving generator.

Current generators include DC generators, synchronous AC generators, and air gap generators.
The generator is a device that generates power when a magnet passes through a coil.

Current generators have poor power generation efficiency relative to the power used.
During power generation, a gogging torque is generated between the magnet and the stator yoke inside the generator, and rotation resistance is generated.
This resistance deteriorates the power generation efficiency.

When the generated power is used, heat is generated in the power generation coil.

During power generation, Joule heat is generated in the stator yoke inside the generator.
This heat hinders the highly efficient power generation of the generator.

When the generated voltage is consumed as electric power, the rotation of the generator is braked in proportion to the power consumption.

The first invention makes smooth rotation during power generation.
The stator yoke is formed into a seamless ring shape, and a power generating coil is wound alternately on the upper part of the coil in a right-handed and left-handed manner.
Since there is no joint, adsorption and separation of the N pole and S pole of the rotor during power generation are eliminated.
Thereby, the gogging torque at the time of generator rotation is eliminated.

The second invention reduces the heat of the coil when the generated power is used.
Heat is dissipated by fixing the coil to the stator yoke.
A feature is that a hole is formed in the stator yoke and a cooling substance is circulated to radiate and cool.

The third invention is to reduce the heat of the stator yoke when the magnet S pole N pole alternately passes through the stator yoke during power generation.
By making the iron wire in which the core coil of the stator yoke is insulated with a coil, the electric resistance is increased and the eddy current is suppressed when the rotor rotates during power generation.
Thereby, Joule heat is reduced.

According to a fourth aspect of the present invention, the magnetic rotor rotates by alternately arranging the right-handed and left-handed stator yokes so that the magnetic poles repel each other when the generated power is consumed.
As a result, the brake for the rotating rotor is reduced.

According to the present invention, in the generator, cooling of the power generation coil and rotation brake during power generation, no gogging torque is generated,
Joule heat is reduced and power can be generated efficiently.

FIG. 2 is a three-dimensional view in which coils are alternately placed on the stator yoke in a right-handed and left-handed manner.

FIG. 6 is a cross-sectional view of a stator yoke provided with cooling holes.

Hereinafter, a power generator according to an embodiment of the present invention will be described.

In FIG. 1, a rotor in which a magnet is assembled to an electromagnetic steel plate is mounted on a rotating shaft with a bearing attached.
It is sectional drawing which fixed the stator yoke to the support | pillar.

FIG. 2 is a three-dimensional view in which coils are alternately installed on the stator yoke in a right-handed and left-handed manner. There shall be an even number of coils and magnets.

3 is a three-dimensional view of the relationship between the stator yoke and the magnet in FIG.
The magnets assembled on the electrical steel sheet are attached on the opposite sides with the same polarity before and after.
The magnets are provided with an even number of polarity N and S alternately. The number of coils and the number of magnets are the same.

FIG. 4 is a plan view showing the relationship and operation in which magnets are alternately attached to a disc-shaped electromagnetic steel sheet in N and S poles.

N poles and S poles are alternately arranged on magnets mounted on electrical steel sheets. The stator yoke and magnet are an even number set.

The relationship between the coil and the magnet when using generated power is as follows.
When the upper and lower magnets N pole 29 moves to a position between 13 and 14, an S pole is generated at 13 and an N pole is generated at 14.
When the upper and lower magnets S pole 30 moves to a position between 15 and 16, N pole is generated at 15 and S pole is generated at 16.
When the upper and lower magnets N pole 31 moves to a position between 17 and 18, an S pole is generated at 17 and an N pole is generated at 18.
When the upper and lower magnets S pole 32 moves to a position between 19 and 20, N pole is generated at 19 and S pole is generated at 20.

When the upper and lower magnets N pole 33 moves to a position between 21 and 22, the S pole is generated at 21 and the N pole is generated at 22.
When the upper and lower magnets S pole 34 moves to a position between 23 and 24, N pole is generated at 23 and S pole is generated at 24.
When the upper and lower magnets N pole 35 moves to a position between 25 and 26, the S pole is generated at 25 and the N pole is generated at 26.
When the upper and lower magnets S pole 36 moves to a position between 27 and 28, N pole is generated at 27 and S pole is generated at 28.

When the upper and lower magnet S poles 30 are moved to the position between 15 and 16, they are repelled by the S pole magnetism generated at the 16 position.
Further, it is attracted to the N pole magnetism generated at 15.
At this time, the brake is normally applied to the rotating direction of the magnetic rotor, but the brake is reduced by the arrangement according to FIG.
According to the installation relationship of FIG. 4, the magnetism is weakened by the repulsion between the 14 and 15 N poles.
Magnetism weakens due to repulsion between the 16 and 17 S poles.

When the rotor rotates, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, and 13 are in the same state.
This weakens the brake against the direction of rotation of the magnetic rotor.

Fig. 5 An iron wire is wound into a coil and used as a core of a stator yoke.
As a result, when the rotor rotates during power generation, the electric resistance is increased, eddy current is suppressed, and Joule heat is reduced.
FIG. 6 By providing a cooling hole in the stator yoke, the stator yoke is cooled, and the coil is similarly cooled.

A generator with good power generation efficiency can be manufactured by reducing heat generation and driving loss during power generation.
