Abstract: An nonlinear torsional vibration characteristics of permanent magnet synchronous motor’s rotor system under the electromagnetic and mechanical excitations were investigated. The model of electromechanical excitation was derived by an energy method. The method of multiple scales was used to solve the equation of motion. The steady state solutions and stability were determined. The effects of inner power factor angle, pole pairs, saturation coefficient and torsional stiffness of shaft on rotor system torsional vibration were studied. The results indicate that it could avoid the amplitude jump and bifurcation instability phenomenon through the reasonable control of permanent magnet synchronous motors and design of electromagnetic and mechanical parameters.

Key words: electromechanical coupling, PMSM (permanent magnet synchronous motor), torsional vibration, multiscale method, stability
