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.
