Design and Analysis on Stage Control Systems for a Novel Hybrid Excitation Synchronous Motor
摘要
Abstract
A hybrid excitation synchronous motor（HESM） has a significant feature of wide speed-range operation due to the combining of advantages of permanent magnet and electrical excitation motors.This paper proposes a novel wide speed-range stage control method based on the analysis of the field-control capability of HESM and the SVPWM control method.Independent control strategies in different speed ranges are employed,which makes the HESM have good performances in the whole speed range by minimizing the total winding copper loss in a low-speed range and keeping the q-axis component of the back EMF invariable in a high-speed range.Since an excitation current and a d-axis current are applied simultaneously for speed adjusting in the high-speed range,the HESM with the proposed speed adjusting system has a wider speed range than the ones merely employing excitation current for field weakened.The experimental results show that the electromagnetic torque increases about 1/3 in low-speed range by adjusting the excitation and the maximum-speed increases about 150% in high-speed range with the proposed control method.关键词
