Abstract: A stator for an electric rotating machine includes an annular stator core, an outer cylinder fitted on a radially outer surface of the stator core, and a stator coil mounted on the stator core. The stator core is comprised of a plurality of stator core segments that are arranged in a circumferential direction of the stator core so as to adjoin one another in the circumferential direction. The stator coil is fixed to the stator core by a thermosetting resin that is set by induction-heating the stator core. Each of the stator core segments is formed by laminating a plurality of steel sheets in an axial direction of the stator core and fixing at least some of the steel sheets by staking. The number of staking portions formed in one of the steel sheets is different from the number of staking portions formed in another one of the steel sheets.

Abstract: A stator for a rotating electric machine includes a stator core and a stator coil. The stator core is formed of a band-shaped steel sheet that is helically bent and laminated. The stator core has slots each opening at an inner periphery of the stator core and spaced from one another in a circumferential direction. The stator coil is formed of electrical conductor segments that are inserted in the slots of the stator core and connected with one another. The band-shaped steel sheet has slits each of which is formed, at a position corresponding to one of the slots, to be open to the corresponding slot. Each of the electrical conductor segments is substantially U-shaped and has a pair of leg portions respectively inserted in corresponding two of the slots of the stator core; the corresponding two slots are circumferentially apart from each other by two or more slot-pitches.

Abstract: An electric conductor is provided for forming a coil upon being bent. The electric conductor includes a pair of electric conductor wires and an insulating coat. The electric conductor wires each have a substantially rectangular cross section and are arranged in alignment with each other in an alignment direction. The alignment direction is perpendicular to corresponding sides of the substantially rectangular cross sections of the electric conductor wires; the corresponding sides have the same length. The insulating coat is formed on outer peripheral surfaces of the electric conductor wires. The insulating coat has a thick portion formed at a boundary between the electric conductor wires. The thick portion is thicker than and protrudes outward from other portions of the insulating coat which adjoin the thick portion in a circumferential direction of the electric conductor.

Abstract: A rotary electric machine has a rotor, a stator with a stator core, an outer cylinder, a stator winding an end plate, and a refrigerant rail, and a cooling unit that drips a liquid refrigerant to an end part of the stator winding for cooling. The ring-shaped end plate is supported by the outer cylinder in at least one side in an axial direction of the stator core. The refrigerant rail with a dripping port where the supplied liquid refrigerant is dripped onto the coil end part is integrally formed at least with one of the end plates.
