Description

DETAILED DESCRIPTION OF THE INVENTION

(Industrial application field) The present invention is absolutely necessary in the industry where power is required in the industrial field.

2. Description of the Related Art Conventionally, a DC intermittent current is applied to a motor field pole ring to cause a change in magnetic force, so that the field pole ring of a motor using a rotator attraction method directly energizes all turns. For this reason, a large back electromotive voltage is generated within the total number of turns when the power is supplied, and the input voltage is disturbed, so that a high voltage is required.

(Problems to be Solved by the Invention) Conventionally, when current is directly supplied to all the number of turns of the field pole ring,
An electromotive voltage opposite to the energizing direction is generated to try to prevent energization.This action reduces the back electromotive voltage to make it more efficient than before, and reduces the generation of back electromotive voltage during energization. A positive electromotive voltage is generated in the same direction as the current energizing direction. The present invention solves the problem that the back electromotive voltage in the total number of windings can be reduced by making the most of the positive starting voltage of the square row when reducing this current, and sufficient current can be supplied even if the incoming voltage is reduced. .

(Means for solving the problem) A large number of branch wires 3 are output from a winding 2 wound around an iron core 1 and connected to a commutator 4. When the brush 6 slides, the branch wire 3 is sequentially connected to the commutator 4 from 0 turns to the maximum number of turns and finally to 0 turns. The rotation angle differs by 180 degrees. While sliding brush 6,
When the number of turns in a set is 0, the number of turns in the other set becomes the maximum number of turns. When the number of turns on the 0-turn side is increasing sequentially, the number of turns on the maximum number of turns is gradually reduced to 0. During the increase / decrease of the number of turns, the side where the number of turns increases increases the counter electromotive voltage, and the side where the number of turns decreases decreases generates the positive electromotive voltage. Regardless of the position of the brush 6, the windings 2 are always provided as direct wirings.
The back electromotive voltage and the positive electromotive voltage are mutually reciprocal, and the back electromotive voltage is reduced on the input side as a whole. In this way, the above-described action works as two sets of one set. When two sets are combined and linked, the rotation angle brush of each set 6
Is set at 45 degrees. The rotating shaft 11 shown in FIG.
It is fixedly connected to the rotation shaft 11 in FIGS.
The symbols A2 and A1 in FIG. 1 and B2 and B1 in FIG.
The magnetic pole winding signal 9 indicates the position of the magnetic pole 8 and the winding 2 in the figure. Although the drawings of the branch line 3 and the commutator 4 in FIGS. 1 and 2 are simple and few, in reality, the direction and direction of the magnetic poles do not change even if there is a strong or weak change in the magnetic force which results in a complicated structure.

(Operation) FIG. 1 FIG. 2 FIG.
Is one, each brush 6, brush holder 7 and rotator 1.
0 is attached and fixed. When the rotator 10 is attracted to the magnetic pole 8 and moves, the brushes 6 move in the same manner and at the same time sequentially move to the respective windings 2 through the branch wires 3 to increase or decrease the number of turns of the coil of the magnetic pole 8.

(Embodiment) Referring to the drawings, an embodiment will be described. Since the winding 2 shown in FIGS. 1 and 2 is a direct wiring, when a current is supplied, a magnetic pole winding is applied to the magnetic pole 8 of the iron core 1 shown in FIG. Symbol 9,
, A magnetic force having many windings 2 is generated in each magnetic pole 8,
In the figure, A1 is the maximum number, the magnetic force is strong, A2 is the number 0, there is no magnetic force, B1 and B2 are half turns, and the number of turns is weak. When the rotator 10 is attracted and moved toward A1, the brush 6 in FIGS. 1 and 2 also moves. As the number of turns increases or decreases. The number of turns of A1 decreases and the number of turns of the next B2 increases, the magnetic force increases, and the rotator 10 attracts. This operation is sequentially repeated so that the rotator 10 that moves and rotates is in the suction state at any position. The rotator 10 rotates continuously.

(Effects of the Invention) The present invention measures the increase / decrease of the number of turns of the field pole winding, and calculates the back electromotive voltage when the number of turns increases and the back electromotive voltage within the total number of turns by the positive electromotive voltage when the number of turns decreases. It has been developed to serve the purpose of reduction. The back electromotive voltage can be reduced by several tens of percent compared with the model of the conventional method.
