載の回転電機の単層巻巻線。[Claims for Utility Model Registration] (1) An upper coil in which the shape of the end portion of a coil with one conductor in one slot is extended with straight portions at both ends;
There are three types of coils: a lower coil in which both ends are bent downward from the upper coil, and an upper and lower coil in which one end is in the upper coil shape and the other end is in the lower coil shape, and the bending direction of the tip of each coil end is in the direction of the coil straight part For each type of coil, coils of the same shape are arranged with their positions shifted in the axial direction within the single-phase band so as to maintain a predetermined space between the coils at the coil ends, and adjacent A single-layer winding for a rotating electrical machine, characterized in that the coils are connected between phase bands of the same phase by providing crossover wires at both ends for connection in the same manner as chain winding. (2) The coil straight portion has a long Lebel dislocation so that 360° of Lebel dislocation can be accommodated within the core length even if it is shifted with respect to the iron core. Single-layer winding for rotating electric machines. (3) Single-layer winding for a rotating electric machine according to claim 1 or 2 of the utility model registration claim, characterized in that the mutual interval between the upper coil and the lower coil at the coil transition portion is equal to or greater than the slot depth. line.
