- Abstract
- Magnetic gear which is capable of non-contact torque transmission has replaced mechanical gear and has advantages of high efficiency and improved reliability. However, it also has the problem of a low torque density, which requires improvement. In this paper, a novel pole piece shape was proposed in order to improve the problem of low torque density of the magnetic gear. In order to identify the functional relationship between design variables of the proposed pole piece shape and response variables such as torque and torque ripple, response surface methodology was used, and Box-Behnken design was used to establish the design of experiment. In addition, using variance analysis and regression analysis of design variables and response variables, response surface of the response variable to the design variable, and its response surface equation, were estimated to derive optimal design variables for the proposed pole piece shape. The experimental data required for predicting the relationships among them are were obtained using finite element method based on 2-D numerical analysis. Therefore, this paper derived an optimal model for the magnetic gear with the novel pole piece using the Box-Behnken design, and the validity of the optimal design of the proposed pole piece shape through variance analysis and regression analysis was demonstrated.
