Abstract

PURPOSE:To make it possible to obtain compact and light weight equipment by providing two sets of the connected stabilizing windings, grounding the ends of the stabilizing windings which face the ends of the other stabilizing windings, and imparting the same polarity to two sets of the concentric stabilizing windings for every phase. CONSTITUTION:Two sets of the stabilizing windings are provided. The first set comprises three stabilizing windings 15, 16, and 17, and the second set comprises three stabilizing windings 18, 19, and 20. They are wound around cores 1, 2, and 3. In this case, the winding direction of the stabilizing windings 17 and 20 which are wound around the core 3 of a third leg is opposite to the winding direction of the other stabilizing windings 15, 16, 18 and 19. Terminals a1-c2 of the stabilizing windings of two sets are connected as shown in the Figure, thereby forming two sets of DELTA connections. For the cores 1 and 3 of the first and third legs, the stabilizing windings 15 and 17 of the first set are wound inside, and the stabilizing windings 18 and 20 of the second sets are wound outside. For the core 2 of the second leg, the stabilizing winding 19 is wound inside, and the stabilizing winding 16 of the first set is wound outside. The terminal (b1) of the stabilizing winding of the first set and the terminal (a2) of the stabilizing winding of the second set are grounded.
