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 Uto U, respectively, and that slot y of group Ux are slot Uxy, a coil starting from the slot UA is wired to pass through one turn of a stator in the order of slots UA→UB→UB→UC→UC→UA, and connected to slot UA of the next turn. In this turn, coil segments with a wide straddle width are used for the connections of UA→UB and UB→UC, and a coil segment with a narrow straddle width is used for the connection of UC→UA.
