摘要：
This paper analyzes the vibration due to magnetostriction in axial flux (AF) permanent magnet (PM) machines with amorphous metal cores (AMCs). First, an analytical model is developed to predict the vibration due to magnetostriction. The solution regions of the analytical model are divided into yoke and teeth subdomains. Then, the effect of processing technics on the vibration of AMCs which is unable to consider in the analytical model was examined using measurements of vibration of AMCs. Through comparing the analytical results and experimental results, the correction factors of vibration acceleration are obtained. Finally, the vibration analysis of a 7 kW AF PM motor with AMCs is carried out by the analytical model.
