Abstract
Eccentric rotor motion of an electric motor induces an unbalanced
magnetic pull. This eccentricity force can be described using a simple
parametric model with physical parameters. This model allows an
arbitrary rotor motion and transient operation. This paper presents an
effective method to estimate the parameters from simulation results of
electromagnetic fields. Further, the numerical results verify the form
of the proposed parametric model in steady-state operation.
