A high power density magnetic compression power generation mechanism and a generator including the same

Abstract

The invention discloses a high-power density magnetic compression power generation mechanism. The high-power density magnetic compression power generation mechanism comprises a stator part and a rotorpart, wherein the stator part comprises first stator iron cores, and a plurality of second stator iron cores which are independent from the first stator iron cores and are vertically arranged; the plurality of second stator iron cores are distributed in parallel; a frame-free coil is arranged between the end part of each second stator iron core and the first stator iron core, and the gaps betweenthe plurality of second stator iron cores are communicated with the gaps between the plurality of frame-free coils to form a plurality of linear motion spaces; the rotor part comprises a plurality ofstrip-shaped permanent magnets which are in parallel and a rotor which is connected with the strip-shaped permanent magnets; and the plurality of permanent magnets are inserted into the linear motionspaces respectively, and high-frequency reciprocating movement is carried out under the driving of the rotor, so that the magnetic flux of the frame-free coils changes violently in the short time, and high electric potential is induced. The invention also discloses an electric generator comprising the power generation mechanism. According to the mechanism, the magnetic flux of the coil changes violently in the short time through high-frequency translation movement, so that high-power density power generation is realized.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a high power density magnetic compression power generation mechanism and a generator including the same. Background technique [0002] The power generation principle of the power generation mechanism is mainly to use the electromagnetic induction phenomenon to generate an induced electromotive force in the coil by changing the magnetic flux in the coil, and the magnitude of the induced electromotive force is related to the number of turns of the coil and the change of the magnetic flux passing through the coil The rate is directly proportional. Therefore, in order to obtain a higher induced electromotive force, for the parameter design of the generator itself, it should have a stronger magnetic field environment and more coil turns. [0003] At present, in the power generation mechanism that uses permanent magnets to provide a magnetic field environment, the power gener...

AI Technical Summary

Problems solved by technology

The space reserved for the relative movement between the coil and the permanent magnet will also occupy a larger volume of the power generating device.

This has greatly restricted the ratio of the power generation efficiency of the power generation mechanism to its volume, resulting in the problems of insufficient power density and low integration of traditional power generation units
