Abstract

Currently, radial motors using laminated steel sheets are the mainstream for motors, but the needs for automotive applications, miniaturization and higher output are increasing. For these trends, we have demonstrated that axial gap motors with soft magnetic powder cores are effective for thinning and high power output for radial motors of the same size. In this presentation we will introduce the latest situation of the development of softmagnetic powder core contributing to high performance of various motors including the above-mentioned motors and examples of application to motors.
