Vertical electrical motor using soft magnetic composites

Abstract

Soft magnetic composites (SMCs) are today a viable alternative to steel laminations in a range of new applications, such as rotating machines, sensors and fast switching solenoids. SMC components are successfully manufactured using the powder compaction process. The isotropic nature of the SMC combined with the unique shaping possibilities makes available 3D-design solutions such as described herein. If carefully implemented advantages such as better performance, reduced size and weight, fewer parts and lower cost can be obtained. This paper focuses on how material properties are affecting the motor performance for a novel motor design. The study is supported by 3D FEA software and prototype measurements. The software allows us to study the effects of material changes on a defined model. The simulations are carried out with the rotor running. Motor performance using different Somaloyreg materials is compared with measurements
