A new rotor for a rotating electric machine assuring outstanding durability and reliability against vibration and facilitating equalization of resistances among a plurality of rotor coils, while allowing the leading ends of a plurality of lead wires to be disposed so as to congregate in one area, is provided. A plurality of stator coilswound at a cylindrical stator coreeach include leader portions led out from one of two ends of a slot along the axial direction and extending astride a plurality of slots. Lead wireseach formed at one end of a stator coilare disposed so that their leading ends, oriented in the same direction, congregate in a single area. In a leader portion where a lead wireis located, a turnback portion, made to turn back with an angle equal to or greater than 90&#xb0; from an inclining wire portion, which is led out with an inclination along a predetermined direction from the slot, is formed.

Stator for rotating electric machine

A rotating electric machine includes a rotor and a stator. The stator coil of the stator includes a set of a first stator coil and a second stator coil that is stored in an adjacent slot to a slot in which the first stator coil is stored, with a number of the set being same as a number of phases, and one end of each of the first stator coil and the second stator coil is a lead section and an other end is a neutral point. A plurality of the stator coils are arranged radially in layers in each slot, and a lead section of the first stator coil and a lead section of the second stator coil are connected with each other with one of the lead sections extending from an outermost layer of the slot and an other of the lead sections extending from an innermost layer of the slot so that the connected lead sections constitute an external connection terminal.
