摘要：
The magnetostriction effect of magnetic material is one of the main causes of the motor vibration and noise. In order to calculate stator core vibration caused by magnetostriction for radial flux (RF) motors, a precise analytical model of such stator core vibration is set up based on piezomagnetic equations and Newton's second law. The relationship among physical quantities is illustrated by the analytical model. Stator core vibration due to magnetostriction is proportional to the magnetostriction coefficient. The vibration displacements of stator yoke and teeth are approximatively linear with the yoke radius and tooth height respectively. The influence of elasticity modulus on vibration caused by magnetostriction is very small. At last, by comparing the results of the analytical model, the finite element method and the experiments, the accuracy of the proposed analytical model is verified.
