Surrogate Modeling and Application of Half-Wave Rectified Brushless Synchronous Motor for Model-Based Design

Abstract

This paper presents a surrogate modeling technology and the application using the response surface methodology (RSM) for a half-wave rectified brushless synchronous motor (HRSM) for model-based design. HRSM adopts a field winding that is singlephase short-circuited through a diode, instead of a brush at the rotor. This brushless excitation facilitates the maintenance of the motor and variable field flux operation. However, creating a high accuracy motor model for model-based design using HRSM considering field current characteristics with the effects of the diode is difficult, and the problem of an unrealistic complex calculation for applications such as drive cycle simulations exists. To overcome these challenges, we propose a surrogate modeling technique for HRSM using RSM and finite element analysis. The objective of this study is achieve the fast and accurate simulation to predict the wide range and long-time driving conditions of HRSM, which is difficult to validate experimentally.
