Abstract
PURPOSE: To perform stable voltage-reduced starting, by short-circuiting the middle points of all the phases of windings delta-connected at the time of starting to double- Y-connect the windings when shifting the starting operation to the full-scale operation.
CONSTITUTION: At the time of the starting, the outer windings u and v', v and w, w and u' of the adjacent groups U and V, V and W, W and U are connected in series with each other. At the same time, the double windings of each phase, for example, u and u, v and v, w and w are connected in series or in parallel with each other, thereby deltaconnecting all the windings to one another. In the full-scale operation, the middle points a, b, c of all the winding groups are short-circuited and two windings u and u', v and v', w and w' of all the groups are coupled in parallel with each other, thereby double-Y-connecting all the windings to one another.
