A linear magnetic flux compression power generation mechanism and a generator including the same

Abstract

The invention discloses a linear magnetic flux compression power generation mechanism comprising a first part and a second part. The first part comprises two U-shaped magnetic steels with opposite openings, a permanent magnet is fixedly disposed on the inner side of each end part of the two U-shaped magnetic steels, and the end parts of the two U-shaped magnetic steels and the permanent magnets are separated by low magnetic conductive materials, and a linear channel is formed between the permanent magnets and the low magnetic conductive materials, which are oppositely arranged in the two U-shaped magnetic steels. The second part comprises a winding framework and a magnetic steel block, which are arranged in the linear channel, and a coil winding is wound outside the winding framework, andthe magnetic steel block is arranged inside the winding framework, and the two end surfaces of the magnetic steel block are opposite to the end surfaces of the permanent magnets and the low-permeability material on the two sides of the magnetic steel block. The first part and the second part are capable of carrying out relative reciprocating high-frequency motion under action of external force. Agenerator is also disclosed. According to the invention, the two separated U-shaped magnetic steels and the permanent magnets are arranged, and the magnetic steel block and the coil winding are arranged in the U-shaped magnetic steels and the permanent magnets, so that the magnetic flux in the coil winding is changed drastically in a short time, and high electromotive force is generated to outputelectric energy.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a linear magnetic flux compression power generation mechanism and a generator including the same. Background technique [0002] The traditional magnetic flux compression generator is based on the continuous short circuit of the armature and the brush spiral winding to reduce the inductance, thereby increasing the current and changing the induced electromotive force. Although higher power can be obtained, its structure is complicated and it is difficult to use it in various devices. . At the same time, not only more enameled wires are needed, but also more copper materials are consumed, and the manufacturing cost is high. [0003] Therefore, there is an urgent need to invent a new type of high-compact, high-power-density power generation mechanism, which can ensure high-power output power while having a simpler structure, reducing unnecessary device usage, and being appl...
