ELECTRO-MAGNETO-MECHANICAL CHARACTERIZATIONS OF THE VIBRATION OF MAGNETIC ORIGIN OF ELECTRICAL MACHINES

This paper contributes to the modeling of vibration of magnetic origin of electrical machines. It is generally difficult to calculate the da mping matrix of actual mechanical structure of electrical machines. Me chanical model that we present here is known as the modal superpositio n method. It allows us to take into account the damping coefficients o f the mechanical structure which can be inferred from experience. Asso ciated with a numerical code for the computation of magnetic force it can be of a great help in the predetermination of the vibration of an electrical machine.
