Abstract EN
This paper is dedicated to investigating static eccentricity in a three-phase LSPMSM.
The modeling of LSPMSM with static eccentricity between stator and rotor is developed using finite element method (FEM).
The analytical expression for the permeance and flux components of nonuniform air-gap due to static eccentricity fault is discussed.
Various indexes for static eccentricity detection using stator current signal of IM and permanent magnet synchronous motor (PMSM) are presented.
Since LSPMSM is composed of a rotor which is a combination of these two motors, the ability of these features is evaluated for static eccentricity diagnosis in LSPMSM.
The simulated stator current signal of LSPMSM in the presence of static eccentricity is analyzed in frequency domain using power spectral density (PSD).
It is demonstrated that static eccentricity fault generates a series of low frequency harmonic components in the form of sidebands around the fundamental frequency.
Moreover, the amplitudes of these components increase in proportion to the fault severity.
According to the mentioned observations, an accurate frequency pattern is specified for static eccentricity detection in three-phase LSPMSM.
