Abstract :
This paper presents the Permanent Magnetic Synchronous Motor (PMSM) with the rotor misalignment; the asymmetric motor magnetic field in each section is varied due to varied eccentricity in axis direction. This asymmetric field generates Unbalanced Magnetic Pull (UMP), and the analysis shows that, the UMP value varies in the motor operation. The paper presents an analytical model for analyzing the 3D effects of the UMP induced by the misalignment rotor. The Simulation results done by ANSOFT prove the effectiveness of the proposed analytic method.
