Title (EN) LIQUID CRYSTAL POLYMER FOR ELECTRIC COMPONENT INSULATION
(FR) POLYMERE A CRISTAUX LIQUIDES POUR L'ISOLATION DE COMPOSANTS ELECTRIQUES
Abstract:
(EN) Conventional insulating resins for electric motors, transformers, connectors or terminals have poor electrical, thermal and structural characteristics. Molded liquid crystal polymers of the invention offer improvements in these areas. In a typical embodiment, iron cores (2) around a shaft bearing (3) can be embedded in the liquid crystal polymer (1) by injection molding. Coils (4) can then be wound on the molded polymer surface.
(FR) Les résines isolantes traditionnelles pour les moteurs électriques, les transformateurs, les connecteurs ou les bornes ne possèdent pas de bonnes caractéristiques électriques, thermiques ou structurelles. Les polymères à cristaux liquides moulés décrits présentent des améliorations dans ce domaine. Dans une application type, des noyaux de fer (2) entourant un palier d'arbre (3) peuvent être noyés dans le polymère à cristaux liquides (1) par moulage à injection. Des bobines peuvent alors être enroulées sur la surface du polymère moulé.
