Abstract
In this paper the Krylov subspace method is investigated regarding its use for the vibration analysis of a stator of an electric machine. It is compared to the full order direct integration method as well as common reduction methods like the mode superposition. It is found that the Krylov subspace method provides much better and faster results than the mode superposition as it is commonly used. Even if complex load cases are applied to the stator the Krylov subspace method reliably produces accurate results which in case of the mode superposition are only achievable performing a residual vectors correction.
