Abstract :
Magnetic vibrations of induction machines are reduced, over a large frequency band, with a breaking of the impedance interface between the stator core and frame. A 2-D finite element dynamic response simulation is proposed. It is based on an experimental determination of magnetic forces and homogenized characteristics of windings, and on a modal analysis enhanced by a gradient method
