Abstract[English]
An electric motor (10) includes a rotor (12) and a stator (14). The stator (14) includes laminated steel plates (16) assembled in a stack (18), with axially extending openings (20) that extend through the stack (18) for receiving stator coil wires (22). Insulating inserts (30, 30') are provided, with one extending through each of the openings (20) that receives a stator coil wire (22). The insulating inserts (30, 30') are formed as plate connecting inserts (30, 30') having a hollow body (34, 34') with a coil wire receiving channel (36), and a first end (31) is slidably inserted into one of the axially extending openings (20) and a second end (32) with a head (38) is seated against an axially outermost one of the plates (16). A first subset (30A) of the inserts (30, 30') are inserted with the respective heads (38) on a first axial side (18A) of the stack (18), and a second subset (30B) of the inserts (30, 30') are inserted with the respective heads (38) on a second axial side (18B). Stator coil wires (22) extend through the coil wire receiving channels (36).[French]
La présente invention concerne un moteur électrique (10) qui comprend un rotor (12) et un stator (14). Le stator (14) comprend des plaques (16) d'acier stratifiées qui sont assemblées en un empilement (18), des ouvertures (20) qui s'étendent axialement s'étendant à travers l'empilement (18) pour recevoir des fils (22) de bobine de stator. Des inserts (30, 30') isolants s'étendent dans chacune des ouvertures (20) qui reçoivent un fil (22) de bobine de stator, chacune desdites ouvertures comportant un seul insert. Les inserts (30, 30') isolants se présentent sous la forme d'inserts (30, 30') de raccordement de plaques ayant un corps creux (34, 34') doté d'un canal (36) de réception de fil de bobine, et une première extrémité (31) est insérée de manière coulissante dans l'une des ouvertures (20) s'étendant axialement et une seconde extrémité (32) dotée d'une tête (38) est placée contre une plaque axialement la plus à l'extérieur parmi les plaques (16). Un premier sous-ensemble (30A) des inserts (30, 30') est inséré avec les têtes (38) respectives sur un premier côté axial (18A) de l'empilement (18), et un second sous-ensemble (30B) des inserts (30, 30') est inséré avec les têtes (38) respectives sur un second côté axial (18B). Les fils (22) de bobine de stator s'étendent dans les canaux (36) de réception de fil de bobine.
