Abstract

L'invention porte sur une structure d'isolation de stator de moteur qui comprend un disque de structure d'isolation (1) revêtant l'intérieur d'un noyau de fer de stator. Une pluralité de dents polaires (2) sur lesquelles sont enroulées des bobines d'enroulement (3) sont disposées sur le côté extérieur du disque de structure d'isolation (1). Une pluralité de colonnes de montage creuses (4), une borne de fil à pression intégrée (5) et une pluralité de bornes de fil à pression indépendantes (6) sont disposées sur le disque de structure d'isolation (1). Les bornes de fil à pression indépendantes (6) et la borne de fil à pression intégrée (5) sont pourvues de rainures de fil à pression (7) passant à travers les côtés intérieur et extérieur des bornes de fil à pression séparément. Des bandes de limitation (8) sont disposées sur les côtés intérieur et extérieur de la borne de fil à pression intégrée (5) respectivement, chaque bande de limitation (8) étant située au-dessous de la rainure de fil à pression correspondante (7). Le disque de structure d'isolation (1) est en outre pourvu d'une pluralité de colonnes de limitation (9) agencées transversalement, les colonnes de limitation (9) étant fixées aux colonnes de montage (4) et/ou aux bornes de fil à pression indépendantes (6). Cette structure peut non seulement protéger efficacement un fil émaillé, mais également réduire la difficulté de montage d'un moteur et améliorer le rendement de production, et peut éviter des risques de sécurité potentiels et garantir efficacement la durée de vie.
