Vibration and Noise Characteristics of SRM with Hybrid Excitation
하이브리드 여자방식 SRM의 진동.소음 저감 특성
Abstract
The main source of vibration in SRM drive is generated by rapid change of radial force when phase current is extinguished by commutation action. In this paper a hybrid excitation method is proposed to reduce vibration and acoustic noise of SRM. The hybrid excitation has 2-phase excitation by long dwell angle as well as conventional 1-phase excitation. The vibration and acoustic noise are reduced because the scheme reduces abrupt change of excitation level by distributed and balanced excitation.
