AbstractReluctance forces are the main cause of vibration in electrical machines. The influence of magnetostriction is still the matter of controversy. In the article, program Ansys (typical for finite element method) was used to analyze stator deformation due to magnetic forces (Maxwell and magnetostriction) for the different boundaries and different methods by taking into account the windings in the mechanical model. Different parameters of numerical model are important factors affecting the level of magnetostriction deformation.

ABSTRACTThis paper deals with the modeling of materials in which electric, thermal and cross effects between these are important. Also the effect of a magnetic field is included. A basic model and its FEM implementation are discussed. Some numerical test result are given.
