Abstract :
This paper presents an iterative approach to identification of sources and characteristics of rotor and airgap eccentricity and, consequently, unbalanced magnetic pull (UMP) in asynchronous motors. The presented method is based on the number of mathematical modeling techniques, namely: finite elements method (FEM), Lagrangian dynamics and optimal estimation in combination with experimental measurements.
