摘要： 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).-

摘要： Die vorliegende Erfindung stellt eine Statoranordnung zur Verwendung in einem Motor und ein Montageverfahren dafür bereit. Die Statoranordnung umfasst einen Eisenkern (1), der einen zylindrischen Eisenkernkörper und eine Vielzahl von Eisenkernzähnen (11) umfasst, wobei zwischen jeweils zwei in Umfangsrichtung benachbarten Eisenkernzähnen (11) Leiterschlitze (1h) zum Aufnehmen von Leitern (3) gebildet sind, wobei Seitenwände jedes Leiterschlitzes (1h), die durch die Eisenkernzähne (11) gebildet sind, jeweils einen aufgeweiteten Abschnitt (111) umfassen, und wobei die aufgeweiteten Abschnitte (111) einander in Umfangsrichtung gegenüberliegen und sich allmählich weiter voneinander entfernen, da sich die beiden in Richtung radialer Öffnungen der Leiterschlitze (1h) erstrecken; und folienartige Isolatoren (2), die in den Leiterschlitzen (1h) derart aufgenommen sind, dass sie an Umfangswänden der Leiterschlitze (1h) angebracht sind, wobei die Enden der folienartigen Isolatoren (2) an den aufgeweiteten Abschnitten (111) angeordnet sind. Dadurch kommt es beim Einführen der Leiter in die Leiterschlitze nicht zu einer unerwünschten Behinderung zwischen den Leitern und den folienartigen Isolatoren. Die vorliegende Erfindung stellt auch einen Motor bereit, der die Statoranordnung zur Verwendung in einem Motor umfasst, der den gleichen vorteilhaften Effekt erzeugen kann.

摘要： The present application provides an insulating framework, a stator, a motor, a compressor, and a vehicle. The insulating framework comprises: a first support; a second support, disposed opposite to the first support, the second support being provided with a wire slot, the wire slot passing through the wall surface of the second support, a portion of the bottom wall of the wire slot inclining towards the bottom of the second support to form an inclined portion, and the inclined portion being located on the side of the wire slot facing the first support; and a third support, located between the first support and the second support and connected to the first support and the second support. According to the insulating framework provided by the present application, the second support is provided with a wire slot, the bottom wall of the wire slot inclines to the bottom of the second support, and when a wire is wound by means of the insulating framework, the coil extends into the wire slot from the side of the wire slot away from the first support and thus extends from along inclined portion to the bottom of the first support, so that winding of the coil is facilitated; moreover, the wire slot can pre-fix the coil, so that the winding of the coil is more compact, and the fixing performance of the coil is improved.
