Brushless Doubly-Fed AC Excited Induction Machine Drives

Presents the mechanical structures and electric characteristics of Brushless Doubly-Fed Ac Excited Induction Machines, and analyses the circuitry model and vector space relationship of the dirives. Then it discusses the general research in this academic field. Finally, it draws a conclusion of the expansive application in the dield of high-performance, energy saving, variable-speed constant frequency and shock load absorption of the machines in the future.
