摘要: Abstract In this paper, the effect of angular misalignment on transient dynamics a rotor-Active Magnetic Bearings (AMBs) system was examined with numerical analysis. A spatial model misaligned rotor mounted in two identical AMBs is setup to account flexible coupling having torsional and lateral flexibility. The driving powered by an electric motor regime. Three models were used four; six eight magnets. They bias control current. support parameters modeled stiffness damping matrices. These computed through electromagnetic theory derivation magnetic forces. general equations motion driven derived solved using Newmark time integration method. Simulation results carried out determine frequency responses term magnitude. Dynamic come confirm significant influence regime dynamic behavior rotor. Simulated also reveal that vibrations induced more important case four Spectral components response investigated, sort present diagnostic information about signature kind fault
