The second column on soft magnetic materials focuses on their characteristics and applications. One common inquiry we receive is, "We aim to miniaturize motors (increase power density), but it is difficult to achieve this with conventional laminated steel." The soft magnetic composite material 'Somaloy®', which our company is pioneering in development and production, addresses such challenges. Can you recall the keywords from the previous column? High purity, irregular shapes, and insulation coating. ◆ Since it is based on high-purity pure iron: - It has high compressibility and allows for high permeability (high density). ◆ Because it consists of irregularly shaped iron powder: - Complex shapes can be achieved without post-processing through net shaping. - It easily entangles during molding, increasing strength after compression and improving handling. ◆ Each particle is coated with an insulating layer: - This results in low eddy current losses, particularly achieving high efficiency in high-frequency ranges. ◆ Consequently, it enables three-dimensional magnetic circuit design, dramatically improving shape freedom. 'Somaloy®' provides hints for miniaturizing motors (increasing power density). ★ For more detailed explanations or inquiries, please contact here! jumpei.ikeda@hoganas.com ★ Please download the information materials on 'Somaloy®' from the link below.
