Problems solved by technology

Each of the above-mentioned means has its own advantages and disadvantages: the magnetomotive force generated by the straight wire method is self-contained and cannot be closed with the external magnetic flux; the magnetism of the permanent magnet cannot be controlled in real time, and the manufacturing cost is high. It is inconvenient to store and transport during use; the magnetism and attitude of the energized solenoid and the electromagnet are easy to control, but the efficiency of the former to generate a magnetic field is low, the energy consumption is large, and the cost is high, and the latter scientifically configures the structure of the iron core , can significantly reduce the cost of
[0003] However, how to scientifically configure the structure of a giant iron core with a large volume to meet the requirements of low cost, good controllability and high magnetic production efficiency is an unresolved technical problem in the prior art

Embodiment 1

[0039] This embodiment provides a giant iron core structure, refer to figure 1 As shown, it includes: an iron core support 1, which has a certain axial length. The length direction of the bracket 1 is extended, and several installation channels 2 are evenly distributed along the circumferential direction inside the iron core bracket 1; the number of iron cores 3 is the same as the number of the installation channels 2, respectively Correspondingly installed inside the installation channel 2 . Compared with the traditional way of simply merging multiple iron cores together, the giant iron core structure of this embodiment uses less iron core material, high iron core utilization, low cost and high magnetic production efficiency, which is more economical.

[0040] The iron core 3 is a cylindrical structure, the installation channel 2 is a cylindrical channel, the outer diameter of the iron core 3 is basically the same as the inner diameter of the installation channel 2, and the ...

Embodiment 2

[0060] This embodiment provides a giant electromagnet structure, which is a change on the basis of Embodiment 1, such as figure 1 As shown, it includes a giant iron core and wires wrapped around the periphery of the giant electromagnet, wherein the giant iron core is the giant iron core structure described in Embodiment 1.

[0061] The giant electromagnet structure of this embodiment has low cost, good controllability and high magnetic production efficiency.

[0062] As an improvement, several of the above-mentioned giant electromagnets can also be stacked in parallel or uniformly distributed around the circumferential direction, thereby forming a more powerful combined giant electromagnet.

Abstract

The invention provides a giant iron core structure, a giant electromagnet and a combined giant electromagnet, wherein the electromagnet structure includes: an iron core support (1), which has a certain axial length, and a number of mutually disconnected and parallel poles are formed inside. The installation channel (2), the installation channel (2) is extended along the length direction of the core support (1), and several of the installation channels (2) are inside the core support (1) along the Evenly distributed in the circumferential direction; several iron cores (3), respectively installed inside the installation channel (2); cavity (4). The giant iron core structure of the present invention has higher magnetic production efficiency than the traditional way of simply merging multiple iron cores together or a single iron core.

Description

technical field [0001] The invention relates to the technical field of electromagnets, in particular to a giant iron core structure capable of improving magnetic production efficiency, a giant electromagnet and a combined giant electromagnet. Background technique [0002] The means of providing magnetomotive force mainly include energized straight wires, energized solenoids, electromagnets, permanent magnets, etc. Each of the above-mentioned means has its own advantages and disadvantages: the magnetomotive force generated by the straight wire method is self-contained and cannot be closed with the external magnetic flux; the magnetism of the permanent magnet cannot be controlled in real time, and the manufacturing cost is high. It is inconvenient to store and transport during use; the magnetism and attitude of the energized solenoid and the electromagnet are easy to control, but the efficiency of the former to generate a magnetic field is low, the energy consumption is large,...
