Abstract: A motor stator winding structure includes a stator core and slot-positions. The stator core includes an insertion side and an extension side. The hairpin wires are configured to be arranged into slot-positions of the phase slots of the same phases of the magnetic pole regions. A first phase winding includes first hairpin wires of the hairpin wires inserted from an entry phase slot-position of a first phase. A second phase winding includes second hairpin wires of the hairpin wires inserted from an entry phase slot-position of a second phase. A third phase winding includes third hairpin wires of the hairpin wires inserted from an entry phase slot-position of a third phase. The entry phase slot-position of the first phase, the entry phase slot-position of the second phase and the entry phase slot-position of the third phase are located in three different magnetic pole regions respectively.

Abstract: Provided are a motor, a stator, and a manufacturing method of the stator. The stator of the motor includes a stator core and a stator winding. The stator core has a plurality of winding slots formed at an end surface of the stator core in an axial direction of the stator core and arranged at intervals in a circumferential direction of the stator core, and each of the plurality of winding slots extends through an inner wall and an outer wall of the stator core. The stator winding includes at least one coil unit, and each of the at least coil unit includes a plurality of first conductors assembled together. Each of the plurality of first conductors includes at least one insertion portion inserted into a corresponding one of the plurality of winding slots. The coil unit is formed by assembling and connecting the plurality of first conductors. Therefore, when mounting the stator winding at the stator core, the plurality of first conductors may be connected to each other in advance to form the coil unit, and then the coil unit is arranged at the stator as a whole. In this way, the wire embedding process can be simplified, and the batch automated production can be easily realized. Therefore, the structure and assembly steps of the motor can be simplified, thereby improving assembly efficiency of the motor.

Abstract: The present invention relates to a system (450,500) and a method for inserting I-pins into a stator or rotor winding assembly (600), comprising a cylindrical containment (450) for hairpins (100, 200), as well as a circular inner containment (500) axially inserted into the cylindrical containment (450) for hairpins (100, 200) comprising a set of radial slots (456). The inner cylindrical containment (500) comprises an upper circular plate (502) with one or more upper cam recesses (505) and a lower circular plate (503) with one or more lower cam recesses (506) as well as a vertical wall (501) extending from the upper circular plate (502) to the lower one (503) but is mounted in a rotatable manner relative thereto.
The upper and lower cam recesses match each other and are mutually integral and allow accommodating a leg (202) of the I-pins (200), and the vertical wall (501) comprises one or more voids (520) along the entire vertical extension over an arc of circumference. Such voids (520) are positioned so that, upon the relative rotation of the vertical wall (501) with respect to the upper and lower circular plates (502, 503), said upper and lower outlets (505u, 506u) are positioned so as to lead into said voids (520) releasing the leg (202) in a radial slot (456) of said cylindrical containment (450) for hairpins (100, 200).-
