Problems solved by technology

[0004] The application of the superconducting coil reduces the copper loss of the coil to a lower level, and the electromagnetic conversion efficiency and the realized magnetic field strength of the coil are expected to be raised to a new level; the electromagnetic conversion efficiency and the realizable magnetic field strength of the existing iron core technology are getting better This contradiction is becoming more and more prominent; people are looking forward to the discovery of materials with high resistance and high magnetic permeability, and there is still no better solution

Abstract

The invention relates to a quasi-ideal iron core, an electromagnetic conversion device using the same, and a method for producing the iron core and relates to the technical field of electromagnetism. Iron cores in prior art are of rectangular or annular frame structures, iron yoke portions coat coils or coils are bared in external space, magnetic leakage and electromagnetic vortex are large, the magnetic saturation value is low, and electromagnetic conversion efficiency is low. The quasi-ideal iron core is an equal magnetic flux section three-dimensional axisymmetric body or rotation body, an iron yoke coats and surrounds a coil without an air gap, a magnetic circuit is in smooth transition, and all magnetic force lines generated by the coil are directly incorporated into magnetic flux of the iron core, so that magnetic leakage and electromagnetic vortex of the iron core are furthest reduced, electromagnetic conversion efficiency and magnetic saturation values are high, high magnetic field intensity can be achieved by matching a superconducting coil with the iron core, and meanwhile, a production process for the equal magnetic flux section air-gap-free quasi-ideal iron core is disclosed; the iron core can be widely applied to occasions where equal electromagnetism generated by general and ultra-strong magnetic fields is converted.

Description

technical field [0001] The invention relates to the field of electromagnetic technology, in particular to a quasi-ideal iron core, an electromagnetic conversion device using the iron core and a production method of the iron core. Background technique [0002] The application of electromagnetic technology has penetrated into every field of modern social life, and has become one of the main technical supports of modern society. [0003] Electromagnetic conversion is an important field of electromagnetic technology, and coils and iron cores are key equipment for electromagnetic conversion devices. The coil and its accessory devices constitute the conductive part of the device. Due to the existence of the resistance, inductance and capacitance between the conductive wires, heat will inevitably be generated during the conduction process, which constitutes the "copper loss" in the electromagnetic conversion of the device; The part is usually called the iron core, and it is genera...
