Abstract
The unbalanced magnetic pull (UMP) due to the magnetizing angle deviation has a great impact on the safety and stability of the super high speed permanent magnet synchronous machine (PMSM) used in the microturbine generation system. Utilizing the numerical finite element method (FEM), the UMP due to the magnetizing angle deviation with and without the rotor eccentricity was analyzed respectively. Using the calculation results as loads, the natural frequencies and the vibration characteristics of the rotor supported by foil air bearing were obtained. The results show that the resonance frequency is near 740 Hz, and the resonance amplitude increases with the increase of the magnetizing angle deviation. To ensure the safety and reliability of the rotor system, the magnetizing angle deviation of the permanent magnet should be limited to less than 5 degrees.
