Electromagnetic Characteristics and Corrosion Resistance of New Magnetosoft Materials Based on Capsulated Iron Powders

Production of motor-wheels for prototypes of mini-electric vehicles based on new soft magnetic materials

“…Figure 2 shows the magnetization curves measured at 1 kHz for components made of a composite magnetic material based on ABC100.30 iron powder encapsulated with a phosphorus oxide coating. Analysis of experimental data and comparison of them with the results of studies by other authors [3,6] showed that the magnetic induction of a composite material exceeds in magnitude the induction of electrical steel in almost the entire range of magnetic fields. At a voltage H = 22 kA/m for the new composite magnetic material, the induction value is Bm = 1.76 T, and for steel -Bm = 1.7 T with a sample density of ρ = 7.6 g/cm 3 .…”

“…Currently, it is quite obvious that electric transport, thanks to the enormous scientific and technological development in the field of highly efficient electromagnetic motors and batteries, is conquering the world market, and is the embodiment of innovative development [1][2][3][4][5]. The world's leading manufacturers have begun serial production of electric modifications of their electric vehicles.…”

“…Naturally, electric vehicles use electromagnetic motors, and in addition to traction motors, a large number of executive motors are used in rotation systems, control of scanning mirrors and cameras, climate comfort dampers, ergonomic positioning of seats and others. That is, for use in electric transport, a range of various engines is required, the energy costs of which will be consistent and optimized in relation to the function performed [2][3]. The adopted programs for the development of electric transport in Belarus and Uzbekistan [4,[6][7][8][9][10][11] and the action strategy for the further development of the Republic of Uzbekistan for 2021-2025 define the development and use of high-performance equipment, the creation and implementation of new technologies and production capacities, etc.…”

Properties of a composite magnetically soft material based on coated iron powders

“…It was found that the synthesized composite materials have low electromagnetic losses, high values of magnetic induction (up to 2.1 T), and good corrosion resistance. Using such materials in power supplies, chokes, transformers, stators, and rotors of electric machines and other products ensures their stable operation under various conditions [23].…”

Investigation of the heat resistance of a metal-glass composite material based on iron

“…Unfortunately, the research carried out did not address the issues of the operation of such materials at high temperatures. The study of heat resistance and corrosion resistance was carried out in [21][22][23][24],…”
