초록
We mathematically and numerically investigate the characteristics of unbalanced magnetic pull (UMP) in a permanent magnet (PM) motor due to simultaneous existence of static and dynamic eccentricities and uneven magnetization of PM. We mathematically show that pole number ±1 and pole number±2 harmonic components of UMP are generated due to static eccentricity with uneven magnetization and that pole number±m harmonic components of UMP are generated due to static eccentricity with dynamic eccentricity. Finite element analysis is conducted to verify the mathematical equations.
