A Comparative Study on Power Generation Characteristics of Permanent Magnet Synchronous Generators

摘要

Power generation characteristics of two gener-ator systems consisting of a permanent magnet synchronous generator and diode bridge rectifiers are discussed in this paper. One of the discussed systems has three-phase stator windings, and the other has two sets of three-phase (six-phase) stator windings to reduce pulsation in the electromag-netic torque and DC current. Experimental results reveal that the power generation efficiency of the system having six-phase stator windings is higher than that of the system having three-phase stator windings for a light load. The maximum power generation efficiency of the system having six-phase stator windings is almost the same as that of the system having three-phase stator windings.
