Proposal of 3D-stator structure using soft magnetic composite for PM motor

This paper presents 3-dimentional motor core structure using soft magnetic composite. This motor aims to provide high motor efficiency compared with lamination core motor. Soft magnetic composite is applied to the stator to decrease iron loss. Using the magnetic field analysis by 3-dimentional finite element method, we confirmed the usefulness of proposal structure. Furthermore, we studied in the actual motor, and effective results were obtained.
