Abstract

Journal of Vibration and Control, Ahead of Print.
The unbalanced magnetic pull (UMP) induced by rotor eccentricity has been studied for permanent magnet synchronous motors (PMSMs); however, the electromagnetic excitation only considers the magnetic field of the rotor. Meanwhile, the harmonics of UMPs ...
