Effects of Cogging Torque Reduction on Mechanical Noise and Vibration

코깅 토오크 저감이 기계 진동.소음에 미치는 영향

Recently, a lot of efforts have been made to satisfy noise and vibration performance requirements of rotating electric precision machines by the use of various numerical techniques. This paper looks into the enfluence of the magnetization pattern and the shape of air gap which play the role of primary variables of the electro-magnetic circuits, and finally, an experimental verification has been performed to illustrate the efficiency and the advantages or the optimal air gap shape minimizing the cogging torque.
