Analytical Calculation of Vibration Due to Magnetostriction in Permanent Magnet Machines With Amorphous Metal Cores
摘要
Abstract
One of the sources arising the vibration of a permanent magnet machine with amorphous metal cores (AMCs) is due to the magnetostriction effect. In order to calculate the vibration due to magnetostriction effect, the analytical model for AMCs was set up based on piezomagnetic equation. The solution regions of the analytical model were divided into yoke and teeth subdomains. Taking the vibration displacement as variable, the vibration differential equations on the yoke and teeth subdomains were solved by the variable separation method, and the undetermined coefficients were obtained by the boundary conditions. On the basis of this analytical model, the analytic calculation formulas of vibration characteristics were deduced. The analytical model was applicable to the radial flux permanent magnet machines with AMCs, which can be used to predict vibration displacement, vibration velocity, vibration acceleration and stress in AMCs. Finite element analysis results confirm the validity of the analytical prediction.关键词
