Detailed ways

Referring to Fig. 1, Fig. 1 is a sectional view of the present utility model. Frame 1 is the shell of the self-induction superconducting motor, and is also used as a supporting structure. The motor stator is composed of two sets of magnetic palms 2 A and B, and each set of magnetic palms 2 is formed by evenly arranging ferroconductive magnets with the same length, width and gap. Among them, the magnetic palms of Group A correspond to the empty slots of the magnetic palms of Group B, and the magnetic palms of Group B correspond to the empty slots of the magnetic palms of Group A. The superconducting excitation windings 3 are respectively wound on each magnetic palm 2 , the magnetic pole of each magnetic palm 2 is opposite to that of the adjacent magnetic palm, and each excitation winding is connected in series. The appearance of the rotor 5 is formed by uniformly arranged magnetic teeth 6 with the same length, width and depth. The magnetic teeth 6 correspond to the magnetic palms 2, and there is a certain gap between the contact surfaces. The brush holder is installed on the rotor shaft 10, and the brush 7 and the brush 8 are respectively assembled by two brushes, which are not in contact with each other, but are in contact with or separated from the copper sheet at the same time. The brushes are respectively connected to the power supply and the two sets of excitation windings of A and B. The surface of the insulated shaft in contact with the brushes is made of uniformly arranged copper sheets of the same length and width, and each copper sheet corresponds to a magnetically conductive tooth on the rotor. The length ratio of the gap between the copper sheet and the copper sheet is 1:3, so that the contact and energization time between a brush and the copper sheet is only one-third of the separation time. The stationary brush 7 is installed as shown in Figure 1. This position makes the excitation winding of the stator A When starting to be energized and magnetized, the electric brush 8 is opposite, that is, when the electric brush 7 contacts the copper sheet, the electric brush 8 corresponds to the gap.

Referring to Fig. 2, Fig. 2 is the wiring diagram of the present utility model. Group A brushes 7 are respectively connected to the power supply and Group A excitation winding 3, Group B brushes 8 are respectively connected to the power supply and Group B excitation winding 15, and batteries 11 and 12 are respectively connected to the first and second two groups of energized circuits to receive the power of each electromagnetic group. The released energy, semiconductor diodes 13,14 are respectively contained in each battery and the power connection line, stop the power supply current from entering in the battery 11,12.

Working principle of the present utility model: the working principle of the electric motor is mainly to apply the suction motion of the electromagnet to attract the iron medium to the rotatable motor. As shown in Figure 1, when the brush 7 is turned on, the power supply and the excitation winding 3 of the group A are energized. After the excitation winding 3 of the group A is charged, the magnetic field of the stator magnetic palm 2 of the group A enters the magnetic conducting tooth 6 of the rotor, and an attracting motion will be generated to drive The rotor rotates, and when the copper sheet 9 leaves the stationary brush 7, the power supply is interrupted, and the magnetic field energy passing through the exciting winding 3 is immediately converted into electric energy to charge the battery 11. When the brush 8 contacts the copper sheet, the power supply and the excitation winding 15 of the group B are energized, and the electric energy enters the excitation winding 15 of the group B and is converted into magnetic energy. In the physical process, the power supply current is controlled regularly through the brushes, so that the two sets of excitation windings are continuously charged and discharged, and the two sets of stator magnetic palms also continuously attract the rotor magnetically conductive teeth to continuously generate magnetic force and move outward to do work.
