The present invention relates to a single-pole generator, and more particularly, to satisfy the rotational speed and magnetic field strength to determine the electromotive force in the single-pole generator as well as to reduce deterioration due to the wear of the brush, synchronous drive when using two conductor discs It relates to a single-pole generator to make this more accurate.

As shown in FIG. 1, a conventional monopolar dynamo rapidly rotates a disk-shaped metal plate 102 serving as a rotor in close proximity to a disk-shaped permanent magnet 101 serving as a stator to rapidly flow current. The same result is obtained by supplying a current to the load 104 by the contact of the (+) (-) brushes 103 and 103a, the metal plate 102 being rotated by the shaft 105 as a conductor. have.

This is applied to Fleming's right-hand rule. When a conductor rod is moved in a space with a magnetic field, the electrons inside the conductor also move along the bar, and the movement of the electrons in the conductor creates a magnetic field and interacts with an external magnetic field to force the electrons. Will be moved.

Electricity flows because these electrons move inside the conductor. That is, even without a battery, the current flows inside the conductor rod just by moving the conductor rod in the magnetic field. At this time, if the current flows only in the inside of the conductor rod, it stops shortly. If the conductor is connected to the outside of the conductor rod, the current continues to flow along the conductor, which is usually called the induction current. What is presented is Fleming's right hand rule.

When the force to move the rod is F, the magnetic field is B, and the direction of the induced current is I, the thumb, middle finger and index finger of the right hand are extended to be perpendicular to each other.

Thumb = F (force to move rod)

Detection = direction of B (magnetic field)

The direction of stop = I (induction current).

On the other hand, such a single-pole generator is capable of flowing more current as the conductor moves faster, in the case of the single-pole generator shown in Figure 1 because the disk-shaped metal plate 102 is formed in a rather large diameter, the circumferential speed is increased The disadvantage is that the brush wears faster.

Accordingly, in recent years, a cylindrical single-pole generator as shown in FIG. 2 has been proposed, which is a cylindrical iron core 113 arranged concentrically with the outer side of the cylindrical conductor 112 insulated from the shaft 111. ) And the field winding 114 wound around this iron core rotates only the cylindrical conductor 112, which is an armature conductor. Since the magnetic flux 115 breaks the cylindrical conductor 112 in the same direction with respect to the entire circumference, the electromotive force in the same direction will be generated in the cylindrical conductor 112, and the positive (-) (-) will be applied to the cylindrical conductor 112. By grounding the brushes 116 and 116a to the cylindrical conductor 112, a current can flow.

Therefore, the cylindrical single-pole generator as shown in Figure 1, because the circumferential speed of the rotor is slower than the single-pole generator in the form of a disk, the wear of the brush is reduced, but this also causes degradation due to friction between the cylindrical conductor and the brush There is a problem due to wear.

Figure 3 is a circuit diagram showing another aspect of a conventional single-pole generator.

The single-pole generator as shown is configured to rotate in the same direction by connecting the two disk conductors 122, 122a rotated by the shaft (121) (121a) with the synchronous drive belt 123, The brushes 124 and 124a are grounded on the shafts 121 and 121a of the disc conductors 122 and 122a to allow electric current to flow to the load 125.

However, this also reduced the frictional resistance between the cylinder or the disk and the brush on the circumference, but because of the synchronous driving method, high accuracy is required so that imbalance does not occur, there is a problem that causes difficulties in manufacturing and operation.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, its purpose is to satisfy the rotational speed and magnetic field strength to determine the electromotive force in the single-pole generator, as well as to reduce the deterioration due to the wear of the brush, 2 It is to make the synchronous driving more accurate when using two conductor discs.

It is provided with a single-pole generator comprising a shaft insertion protrusion is insulated from the electric shaft inserted into the surface contact in the phase.

In addition, a pair of positive (+) excitation coils on both sides of a pair of copper discs integrally formed on both sides of the insulated copper communication with the drive shaft rotated by the prime mover is arranged concentrically on the outside of the copper cylinder. A pair of copper wheels connected to a copper cylinder and a conductive belt are coupled to both sides of the transmission shaft parallel to the driving shaft, and the copper wheel is wound on the outside of the iron core. Provided is a single-pole generator comprising a shaft insertion protrusion is insulated from the electric shaft inserted into the surface contact and in the cross section.
