Abstract :
The authors describe a way to calculate the mechanical vibrations of the stator and case in the two-dimensional modeling of electrical machines. The mechanical vibrations are the result of the magnetic forces acting on the surfaces of the stator. The vibration calculation consists of three steps: (1) finite element method calculation of the magnetic field; (2) local force density calculation and its Fourier decomposition; and (3) calculation of the dynamic displacements of the electrical machine´s stator and case
