Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a DC generator using multiple brushes and distributors,

The present invention relates to a DC generator using a multiple brush and a distributor,

More specifically, the DC motor is coupled with a pulley or a blade at one end of a rotating DC motor rotary shaft, and at the other end is slidably engaged with a distributor and fixed to the brush holder bracket, The outer surface is composed of a rotor, and the outer surface corresponding to the rotor is composed of a stator.

Unlike a conventional direct current generator, the DC power generator of the present invention has a structure in which the rotor and the stator of the power generator are not rotated at one end of the fixed shaft, the field iron core and the field coils are provided in the field formed on the outer periphery of the fixed shaft, The armature forming the outside in correspondence with the field is provided with an armature core and an armature coil, and a commutator having a commutator element is fixedly coupled to the other end of the stationary shaft.

A commutator brush holder having four pairs of commutator brushes and brush holder brackets is formed outside the commutator.

The distributor having four pairs of short circuits and distributor brackets is formed on the outside of the commutator brush holder.

The distributor is molded into four pairs of short circuits, and is supplied with DC power from a battery and is slidably coupled to the DC motor rotary shaft so as to be in close contact with the commutator brush holder.

The commutator brush holder is provided with four pairs of commutator brushes on its inner and outer side surfaces and is rotated in close contact with the commutator element fixed to the fixed shaft.

The brush holder bracket has a hollow formed at its center to engage the shaft, and is coupled to one end of the DC motor rotating shaft so as to be slip on one end of the rotating shaft.

Therefore, the field and the commutator which are rotated by the conventional generator are fixed, and the commutator brush holder composed of the four pairs of commutator brushes and the brush holder bracket is rotated between the commutator and the distributor by using the DC motor .

When the DC current of the battery is supplied to the DC motor to be artificially driven, the distributor formed with the four pairs of short circuits is simultaneously supplied with the DC current from the battery, while the four pairs of the commutator brush hold- The DC current is supplied and short-circuited repeatedly to the commutator brushes of the four cores so as to sequentially induce magnetic force on the field cores by the commutator elements connected to the four pairs of commutator brushes, A magnetic force having a polarity opposite to that of the field iron core is sequentially induced in the armature coil to obtain a desired electromotive force.

Therefore, the present invention relates to a power generating apparatus that generates an efficient electromotive force by a small external power by rotating a light commutator brush holder using a DC motor, a pulley, or a blade.

The conventional rotary type DC generator includes a rotor, a stator formed outside the rotor, and a housing surrounding the stator. When the rotor rotates, A magnetic flux from a magnet (a rotor mag) interacts with a stator coil to induce a current in the stator coil.

In addition, the voltage characteristic of the conventional DC generator can increase the electromotive force generated by increasing the rotation speed of the rotor or increasing the number of field coils, and that the induction voltage rises as the magnetic flux change of the field coil becomes faster And that the induction voltage rises as the rotational speed and the excited current increase,

In this study, a conventional slip ring is constructed by reversing the movement structure of the conventional DC generator without rotating both the rotor (i.e., the field), the stator (i.e., the armature) and the commutator The commutator brush holder has been devised in which the four pairs of commutator brushes are provided on the inside and outside of the commutator brush in a circular shape with a phase difference of 45 degrees in the clockwise direction,

The four pairs of short circuits are arranged in a semicircular shape so as to closely contact the commutator brush holder on the inner surface of the commutator brush holder so as to maintain a phase difference of 45 deg. The above-mentioned distributor having a hollow cylindrical shape is designed.

Therefore, the commutator brush holder which is light in weight is rotated by the DC motor or pulleyed or bladed to save the external power energy much more than rotating the conventional rotor, and the induction electromotive force of four phases is generated, so that a technique capable of increasing the magnitude and efficiency of the electromotive force generated by the conventional direct current generator is combined and used.

In a conventional rotating-type DC generator, a rotor and a commutator are forcedly rotated by an external power source to generate a current, so that the rotor and the commutator, which have a very heavy weight, The efficiency of friction and other factors is deteriorated as well as waste of power energy required to rotate the rotor.

Therefore, unlike the conventional rotary-type generator, the present invention fixes the existing rotary shaft using a method in which both the rotor and the commutator are not rotated.

And the field core provided with the field iron core and each of the field coils is formed on an outer peripheral surface of one side of the fixed shaft.

And the armature core and the armature provided with the armature coil are arranged so as to face each other in correspondence with the field.

And the commutator formed by the commutator element is coupled to the other side of the fixed shaft.

And the commutator brush holder is closely contacted to the outer periphery of the commutator to be rotated.

Wherein the commutator brush holder includes four pairs of commutator brushes, one side of the commutator brush holder is provided with the brush holder bracket, the central portion of the brush holder bracket is formed so as to insert a shaft, Use a bushing or a bearing on the fixed shaft to slip.

And the other side is fixed to the DC motor rotating shaft to rotate, and the mutually segmented form of the fixed shaft and the DC motor rotating shaft is linearly coupled.

One side of the distributor is equipped with a distributor bracket

And the air blades are coupled to the DC motor rotary shaft so as to be fixed in the direction of the commutator.

And DC current from the battery is coupled to four pairs of short circuits of the DC motor and the distributor.
