Abstract:This paper presents an analytical model suitable for analyzing Permanent Magnet Synchronous motors. The difference between mass eccentricity and magnet eccentricity is described. The full derived vibration mathematical model incorporates both the electrical domain and mechanical domain. The shaft bending force, mass eccentricity exciting force, aerodynamic exciting force, and unbalanced-Magnet-Pull (UMP) are introduced in this three-dimensional motor model. The relative displacement between rotor and stator is… Show more
