A Brushless, Self-Excited Polyphase Synchronous Generator

Abstract
This paper describes principles together with analytic and experimental studies of a brushless, self-excited three-phase synchronous generator which was devised by one of the authors. Steady state analysis of performance of the generator system including a three winding transformer which is connected with the stator winding of the generator and through which the generator can be self-excited is discussed, and test results of a testing equipment including a generator together with a transformer and other apparatus are presented. It is found that a brushless, self-excited three phase synchronous generator having a constant voltage characteristic can be simply constructed.
