Embodiment approach 1

[0023] make figure 1 For the power generation unit shown, place the positioning holes of the power generation unit on a special fixture for positioning, arrange them evenly and weld them figure 2 The 2 connecting wires shown in , require the welded joint resistance to be small and firm. After sequentially welding the 12 power generation units in this example, they are assembled into figure 2 As shown in the single-chip power generation disc, there is a connecting wire in the single-chip disc, which needs to weld the inner protrusion of the last unit of the power generation disc on this layer with the outer end protrusion of a power generation unit on the previous layer, and then weld them sequentially. The remaining power generation units on the next layer are welded until all the power generation units are completed, so that the basic skeleton of the generator rotor is made, and then the Figure 5 Install on the middle input shaft end cover Figure 4 Insulation board, pr...

Embodiment approach 2

[0040] The production of the generator rotor is as in Scheme 1. The generator uses multiple rotors to rotate at the same time, and the rotation speed of the rotors is kept the same through mechanical transmission, and the steering can be the same or reversed.

[0041] The magnetic field source on the stator of the generator can be excited by permanent magnets or electromagnetic coils. Now, the scheme of using two rotors for power generation will be described.

[0042] The two rotors are installed side by side in the same stator, and the rotors are connected by gears or pulleys, and the two have the same rotational angular velocity of the rotors. The excitation magnetic field adopts a horseshoe-shaped magnet frame directly above the two generator rotors, so that the magnetic field generated by the magnets forms a magnetic circuit with the magnet or yoke at the other end of the rotor through the paramagnetic material on the two rotors, so that as long as the input shaft is driven...

Embodiment approach 3

[0046] The generator of this structure can also be used as a DC motor. If the permanent magnet is used as the magnetic pole, it can run continuously only by connecting the DC power supply. If the electromagnet is used for excitation, it is similar to the existing motor to easily realize the conversion of the generator and the motor. . Due to the characteristics of this device, the internal resistance is low, the iron loss and copper loss are low, and the volume of the generator is small. When used as a DC motor, it can achieve high torque output with a small DC voltage.

[0047] At this time, the magnetic field of the motor repeatedly passes through the stacked discs. After the cables at both ends of the discs are energized, the current passes through each power generation unit in turn, and each unit is subjected to the action of electromagnetic force, so that the discs generate torque around the rotating shaft. When the number of disc layers in the motor is large, even if th...

Abstract

The invention relates to a disk high-voltage direct-current generator. The disk high-voltage direct-current generator consists of two parts, namely a stator and a rotor, wherein a power generating disk is combined by connecting the rotor with a connecting lead in series through a power generating unit, and a plurality of groups of power generating disks are superposed to form the generator rotor. The generator adopts the basic principle of Faraday disk power generation, the power generating unit is used for cutting magnetic induction lines of the vertical power generating disks to produce electromotive force, two adjacent power generating units are connected in series by virtue of the connecting lead, and the connecting lead cannot produce reverse electromotive force in rotation through magnetic shielding near the connecting lead to further enable the generator to have a very high power generating voltage. Meanwhile, the generator also can be used as a motor, and the generator and the motor with the structures have the characteristics of small internal resistance without iron loss, simple structure, wide material sources, large capacity, and small volume and calorific value. Used as the motor, the generator also has the advantages of great output torque and wide application range.

Description

technical field [0001] The invention belongs to the electromechanical field, adopts the Faraday disc power generation principle, has no iron loss, low internal resistance, does not need a rectifier and a reversing mechanism, and is a high-voltage DC generator capable of generating very high DC voltage after combining multiple power generation discs. Background technique [0002] The main components of existing DC generators are composed of stator, rotor, generator windings, rectifiers and brushes, etc., and the generator windings are embedded in an iron core made of silicon steel sheets to form a whole. The voltage of existing large DC generators is generally 800V or below, less DC generators with higher voltages are used. If the AC rectification is used, there is iron loss in the DC, and the DC voltage also fluctuates. [0003] The Faraday disk generator uses a conductive disk to rotate in a stable unidirectional magnetic field to cut the magnetic field lines to generate d...
