Investigation of Design Performance in Outer Rotor BLDC Motor for Taguchi Method

This paper optimized the performance of an actual brushless DC electric fan motor with a rated power of 26 Watts by analyzing the simulation of this reference model. Optimization is made based on the Taguchi Method. This study primarily investigates an outer rotor BLDC motor design, and the parameters of interest include torque, output power, and efficiency. The characteristics of the physical brushless BLDC configurations are compared with the proposed design to evaluate the performance of the proposed model. Optimization results using the Taguchi Methods show that the proposed model outperforms the reference design regarding the specified parameters. The ability of the proposed motor simulation result can further be analyzed from its magnetics flux distribution and Finite Element Method (FEM). The paper also compares the characteristics of physical BLDC configurations with the proposed design.
