Japanese steel maker JFE Steel has recently developed Electromagnetic Ro, an insulating coated pure iron powder for dust cores, as an important material mainly used for axial gap motors. As a result, the JFE Group has become the only comprehensive supplier in the world that can provide one-stop and optimal solutions for all power supply equipment including motors, with a wide range of soft magnetic materials from electrical steel sheets to soft ferrite cores. Commercialization of Electromagnetic Steel will provide the optimum soft magnetic materials for almost all frequency ranges currently requiredA dust core is an iron core manufactured by applying an insulating coating to soft magnetic) metal powder and compression molding, and its operating frequency is higher than that of electrical steel sheets that have been widely used as iron core materials in the past. It has low loss in high regions and has magnetic properties suitable for cores with complicated shapes. Since the yield during motor core manufacturing is also good, it is possible to reduce the manufacturing cost of high-speed motors. In addition, the dust core is a product that contributes greatly to the promotion of recycling because it is easy to recover the copper wire when the motor is discarded.The powder magnetic core using the newly developed Electromagnetic Steel is iron that is lower than the electrical steel sheet 50A400 with a thickness of 0.5 mm in the region exceeding 400 Hz and the electrical steel sheet 35A300 with a thickness of 0.35 mm in the region exceeding 800 Hz. It is a loss and is one of the most suitable materials for application to motors with high rotation speed such as axial gap motors.With the progress of electrification of automobiles, there is an increasing need for both high torque and miniaturization of motors. The axial gap motor is a new structure motor that can reduce the motor volume compared to the conventional radial gap motor and is expected to be applied especially to in-vehicle applications.In addition, JFE Chemical Co Ltd has a soft ferrite core that supports high frequency ranges of several tens of kHz or higher as a soft magnetic material for transformers and inductors of electronic devices. Manufactured and sold through JFE Ferrite Ltd.
