Abstract:
1. A short-circuit member assembly for short-circuiting a plurality of segments arranged in a circumferential direction, the segments including m sets of n segments, where m and n are integers, the short-circuit member assembly including a first short-circuit member group and a second short-circuit member group superimposed with each other, the first short-circuit member group including a plurality of first short-circuit pieces arranged in the circumferential direction, the second short-circuit member group including a plurality of second short-circuit pieces arranged in the circumferential direction, with each of the short-circuit pieces including a first terminal, a second terminal located outward or inward in a radial direction from the first terminal and separated from the first terminal in the circumferential direction, and a connecting portion connecting the second terminal to the first terminal; wherein each of the first and second short-circuit member groups includes the short-circuit pieces, the quantity of which is obtained by multiplying (n−1) by m, to short-circuit the n segments in each of the sets with (n−1) first short-circuit pieces in the first short-circuit member group and (n−1) second short-circuit pieces in the second short-circuit member group; m first terminals in the first short-circuit member group and m first terminals in the second short-circuit member group are superimposed with each other and joined to form m first-terminal joint portions, the m first-terminal joint portions and remaining first terminals in the first and second short-circuit member groups are arranged in the circumferential direction and connected to the segments; and all of the second terminals in the first short-circuit member group and all of the second terminals in the second short-circuit member group are superimposed and joined with each other.
