Abstract

Soft magnetic composite (SMC) material is formed by surface-insulated iron powder particles, generating unique properties like magnetic and thermal isotropy, and very low eddy current. This paper presents the design and analysis of a highspeed claw pole motor with an SMC core for reducing core losses and cost. The analyses are conducted based on a comprehensive understanding of the property of SMC materials. Three dimensional (3-D) finite element analysis (FEA) is performed for accurate parameter calculation and dimension optimization. Considering the importance of core loss in high speed motors, rotational core loss model is employed. The design and analyze methods are validated by experiment on the prototype.
