Soft Magnetic Composite (SMC) 'Somaloy(R)' Overview
Soft magnetic material with an insulating coating applied to pure iron powder! Achieving high frequency (miniaturization) by reducing eddy current losses! ☆ Easy molding of complex shapes ☆
"Somaloy(R)" is a soft magnetic material made of pure iron powder with an insulating coating, developed by our company as a world first. It enables the manufacturing of cores with three-dimensional shapes and three-dimensional magnetic properties through mold forming. It is particularly useful for the development and manufacturing of high-spec soft magnetic cores required for miniaturization and high output in applications such as electric vehicles. 【Features】 - High compressibility allows for high permeability. - Enables three-dimensional magnetic circuit design, achieving miniaturization, lightweight, and cost reduction of products. - An insulating coating on pure iron powder results in low eddy current loss characteristics, achieving high efficiency in high-frequency ranges! - Complex shapes can be formed without secondary processing through net shaping (three-dimensional mechanical shapes that can be formed with uniaxial pressure). 【Grades】 - We offer a range of products covering frequencies from 100Hz for motor applications to up to 100kHz for reactor applications. ★ A catalog of "Somaloy(R)" is available for download via the button below.
basic information
"Somaloy(R)" is a soft magnetic material composed of pure iron powder that has been treated with an insulating coating on the particle surface. It enables the formation of complex-shaped components with high dimensional accuracy through the mold compression process alone, and by utilizing the freedom of 3D net shaping and 3D magnetic circuit design, it achieves miniaturization, lightweighting, and cost reduction that were difficult with conventional electromagnetic steel sheets. 【Suitable Application Examples】 ■ Ultra-flat pancake-type axial gap motors (axial flux type) Axial gap motors using "Somaloy(R)" already have a track record of mass production in various automotive motors! ☆ We are also actively providing design technical support for axial gap motors ☆ ■ Boost reactors for automotive DC/DC boost converters Reactors using "Somaloy(R)" already have a track record of mass production in various automotive applications! ★ We will also provide an introduction to the achievements of "Somaloy(R)" ★ For more details, please contact us♪
