Abstract:
1. A rotating electrical machine comprising: a stator including at least two element coils of the same phase each having a plurality of turns and connected to each other through a coil-to-coil connection wire, the element coils being arranged in adjacent slots, respectively; and a rotor rotatably provided to the stator through a gap, wherein: the element coils of the same phase are fitted in the adjacent slots so that wound around portions of the element coils partially overlap each other; the coil-to-coil connection wire connects at a coil end portion of conductor wires extending from linear conductor wire portions of innermost wires of the element coils contained in the slots, the coil-to-coil connection wire is held between the coil end portion and an end face of a stator core in an axial direction, a height of an outer side of the coil-to-coil connection wire in an axial direction is smaller than a height of inner sides of the element coils, in a consecutive double coil including two element coils of the same phase, two linear conductor wire portions in a first element coil and two linear conductor wire portions in a second element coil are arranged alternately in a circumferential direction of the stator, each consecutive double coil comprises a first linear conductor wire portion and a second linear conductor wire portion defined, respectively, in the direction of rotation, and the first linear conductor wire portion of the first element coil and the first linear conductor wire portion of the second element coil are arranged in adjacent slots.
