Abstract :
The paper introduces a damper flux-oriented control method of synchronous machines, and develops a mathematical model of a synchronous motor with damper flux-oriented control. It is proved through theoretical analysis and experiments that a damper flux-oriented drive system has the same steady performance as that achieved with airgap flux-oriented control; moreover the damper flux is not sensitive to the harmonics of the stator currents, and by using the feedback value, the dynamic performances of the drive system can be improved. A 2500 kW 12/6 Hz cycloconverter synchronous motor drive system with damper flux-oriented control has been manufactured and applied in rolling mills in China. The cycloconverter consists of three sets of antiparallel six-pulse bridge rectifiers without circulating current
