Abstract

In this paper, an efficient frequency-domain vibration analysis method for electric machines is presented. The method enables the fast re-analysis of the vibration response of electric machines at various operating conditions without the necessity to re-compute the harmonic response by finite element analyses (FEAs). The mathematical modeling framework is based on the observations that a snapshot of the traveling-wave magnetic force at any time instant can be expressed by a linear combination of amplitude-modulated standing-waves. As numerical examples, forced vibration problem of the stator core of an interior permanent magnet motor at a fixed operating condition, as well as the spin-up test conditions are discussed.
