摘要： A stator has a stator core composed of teeth and slots. Segment coils are inserted into the corresponding slots. The segment coil projecting from the slot has an exposed conductor part and a covered conductor part covered with an electrical insulation film. The exposed conductor part is arranged at the distal end side from the covered conductor part of the segment coil. The segment coils are connected together through the exposed conductor parts thereof projecting from the slots. The exposed conductor part has a thickness T2 thinner than a thickness T1 of the covered conductor part. A step part is formed at a position of the stator core side, adjacent to the exposed conductor part of the segment coil. The step part and the covered conductor part are covered with the electrical insulation film continuously from the stator core side of the covered conductor part.

摘要： Embodiments relate to a stator unit, a stator, and a motor comprising same, the stator unit comprising: a unit stator core; an insulator disposed on the unit stator core; and a coil wound on the insulator, wherein the unit stator core comprises a main body formed so as to have a prescribed curvature with reference to the centre, and three teeth formed so as to protrude toward the centre from the main body, the main body comprising notches formed between the teeth. Thus mass productivity can be increased as a result of series winding using a coil on a unit stator core having three teeth arranged thereon.

摘要： A motor includes a stator that includes an annular core back, teeth extending radially outside from the core back and being arranged in a circumferential direction, an insulator covering at least a portion of the teeth, and a coil defined by a conductive wire wound around each of the teeth via the insulator. A radially inside surface of the core back includes core back protrusions extending radially inside and provided with a space therebetween in the circumferential direction. The insulator includes an annular upper lid portion extending radially inside farther than a radially inside surface of the core back at an axially upper side of the core back and a side wall portion extending to an axially lower side from a lower surface of the upper lid portion. At least a portion of the side wall portion is disposed within the space between the adjacent core back protrusions.

摘要： A stator of an electric rotary machine includes a first abutting portion and a second abutting portion. The first abutting portion and the second abutting portion are welded by laser welding in a state where the abutting portions abut against each other, and the first abutting portion and the second abutting portion include bonding surfaces which are bonded to each other. In the axial direction, a height from an insulating cover film to the bonding surface in one abutting portion is greater than a height from an insulating cover film to the bonding surface in the other abutting portion, and in a radial direction, a protruding distance from the insulating cover film to the bonding surface in the one abutting portion is greater than a retraction distance from the insulating cover film to the bonding surface in the other abutting portion.
