Abstract :
The electromagnetic damp characteristics, namely, the characteristics of electromagnetic torque varying according to angular velocity, of permanent magnet synchronous generator (PMSG) were derived by phasor method. The relationships between the characteristics and PMSG interior parameters were discussed. Transient process and electromechanical time constant were proposed. Both the analysis result and the simulation in MATLAB demonstrate that approximately linear characteristics and non-linear characteristics can be realized by adjusting load resistance and reactance. The result shows PMSG has the potential to be an electromagnetic damper for vehicle vibration absorption.
