Abstract

In this paper, efficiency optimization design is performed for brushless DC motor (BLDC) driving fan in 80W-grade, using a design of experiment (DOE). The magnetic equivalent circuit (EMC) method is used to calculate motor efficiency. In a shape of the motor, parameters affecting the efficiency are selected and main and interaction effects of them are analyzed using a full factorial design. As a result, more influential among parameters are reselected. A quadratic approximation function is estimated, by performing a response surface method (RSM) with the reselected parameters. Finally, a shape of an optimized motor is determined by the estimated function and validity is confirmed by analyzing characteristics of the optimized motor.
