Soft magnetic composites (SMCs) have the following advantages: three-dimensional magnetic isotropy, high resistivity, and recyclability. By using SMC, therefore, a new concept motor with a three-dimensional structure can be developed. Its power-to-space ratio and efficiency can be improved since the space factor of winding and the space utilization factor of the motor is increased. This paper describes a design method of a claw teeth motor made of SMC by reluctance network analysis (RNA)-based experimental design. First, a three-dimensional RNA model of the claw teeth motor is presented. Next, the RNA-based experimental design of the claw teeth motor is presented. As a result, the average torque is improved by approximately 50%. In addition, the calculation time required for the design is significantly reduced by the proposed design method.
