Abstract
Coil segments of the same phase are inserted into each group of circumferentially consecutive three slots. Assuming that the grouped three slots are A, B, and C, and six groups are U1 to U6, respectively, and that slot y of group Ux are slot Uxy, a coil starting from the slot U1A is wired to pass through one turn of a stator in the order of slots U1A→U2B→U3B→U4C→U5C→U6A, and connected to slot U1A of the next turn. In this turn, coil segments with a wide straddle width are used for the connections of U1A→U2B and U3B→U4C, and a coil segment with a narrow straddle width is used for the connection of U5C→U6A.
