Structure-dynamic finite-element simulations of electrical machines allow for vibration analysis concerning geometric variants of the regarded motor without prototyping. In general, the huge disadvantage of these types of simulations is their high computational efforts. In this paper a novel method for the transformation of the surface-force density from the electromagnetic to the mechanical model of the machine is introduced leading to a significant acceleration and more accurate results. For any electric machine whose physical conditions allow for 2-dimensional electromagnetic simulation these advantages can be taken as the results of an induction machine with squirrel-cage rotor show exemplarily.
