The invention relates to a stator (8) for an electric rotating machine (2), which stator has a laminated stator core (16) having coil bars (20) and has at least one stator winding head board (24) having an insulating main body (28). In order to reduce the axial length of the stator (8), according to the invention, conducting tracks (26) are integrated into the insulating main body (28), wherein the at least one stator winding head board (24) lies on an end face (23) of the laminated stator core (16) and wherein the conducting tracks (26) are integrally bonded to the coil bars (20).

A conductor shaping apparatus includes a first shaping die, a second shaping die and a holding section configured to hold the conductor and rotates the second shaping die about a rotational axis with respect to the first shaping die so as to form an edgewise bent portion and a flatwise bent portion in the conductor held by the holding section. The conductor shaping apparatus further includes a first movement restricting portion that is formed in the first shaping die and is configured to contact with a portion of the conductor so as to restrict a movement of the conductor together with the second shaping die when the second shaping die is rotated in a direction approaching the first shaping die, and a second movement restricting portion that is formed in the first shaping die and is configured to contact with a portion of the conductor so as to restrict the movement of the conductor together with the second shaping die when the second shaping die is rotated in a direction apart from the first shaping die.

A stator of a rotary electric machine includes a stator core and a coil. The stator core includes slots extending in an axial direction of the stator core and a first axial end surface in the axial direction. The coil is attached to the stator core and includes slot coils disposed in the slots and connection coils. At least one of the slot coils includes a slit in a part positioned in a slot among the slots. The slit extends through the at least one of the slot coils from a first axial end side of the stator core toward a second axial end side of the stator core opposite to the first axial end side in the axial direction. The connection coils are connected to the slot coils at a contact portion at a position outward from the first axial end surface in the axial direction.

An electrical machine includes a tubular rotor magnetised to have circumferential polar alternations, and a stator including a body that is traversed by a channel having an inner transverse section that substantially corresponds to the outer transverse section of the rotor, the body carrying a plurality of windings, the stator being surrounded by an outer ferromagnetic envelope, the body being extended by three, four or six radial projections made from an electrically insulating material having, in the transverse cross section, a longitudinal core for receiving a winding, the core being extended by a peripheral extension having an outer surface that matches the inner surface of the envelope and covers the wound area. A method for producing such an electrical machine is also provided.

An apparatus for automatically routing a wire lead of a stator from a first position to a second position includes a base assembly to receive the stator. A clamp assembly is mounted on the base assembly to hold the wire lead in the first position. An arbor rotates the wire lead. The arbor has a holder to hold the wire lead. An end effector grips and moves the wire lead. A controller moves the end effector to grip the wire lead at the first position and to couple the wire lead with the arbor. Further, the controller rotates the arbor to rotate the wire lead along the circumference of the stator by a pre-determined angle. The controller moves the end effector to grip the wire lead held by the holder, and to move the wire lead to the second position.

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 coils 102 wound at a cylindrical stator core 101 each 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 wires 300 each formed at one end of a stator coil 102 are disposed so that their leading ends, oriented in the same direction, congregate in a single area. In a leader portion where a lead wire 300 is located, a turnback portion 400, made to turn back with an angle equal to or greater than 90 from an inclining wire portion 113, which is led out with an inclination along a predetermined direction from the slot, is formed.
