Title (EN) SYSTEM AND METHOD FOR ENHANCED MAGNET WIRE INSULATION
(FR) SYSTÈME ET PROCÉDÉ POUR ISOLATION DE FIL DE BOBINAGE AMÉLIORÉE
Abstract:
(EN) A method of making an enhanced magnet wire insulation suited for an electric submersible motor application is described. The method includes drawing copper magnet wire to size and cleaning the copper magnet wire. The method includes pulling the copper magnet wire through a polyimide wrap machine to produce wrapped copper magnet wire and placing the wrapped copper magnet wire around a spool. The method includes heating the wrapped copper magnet wire by unspooling the wrapped magnet wire through a tube comprising an induction coil and removing moisture from the heated, wrapped copper magnet wire by creating at least a partial vacuum inside the tube. The method includes redrawing the wrapped copper magnet wire through an extrusion mold after moisture is removed. The method includes applying molten PEEK to the wrapped copper magnet wire to produce enhanced magnet wire and winding the enhanced magnet wire into an induction motor.
(FR) L'invention concerne un procédé de fabrication d'une isolation de fil de bobinage améliorée appropriée pour une application de moteur électrique submersible. Le procédé comprend le tréfilage d'un fil de bobinage en cuivre à dimension, et le nettoyage du fil de bobinage en cuivre. Le procédé comprend le passage du fil de bobinage en cuivre à travers une enveloppeuse sous polyimide pour produire un fil de bobinage en cuivre enveloppé, et le placement du fil de bobinage en cuivre enveloppé autour d'une bobine. Le procédé comprend le chauffage du fil d'aimant de cuivre enveloppé par débobinage du fil de bobinage enveloppé à travers un tube comprenant une bobine d'induction, et l'élimination de l'humidité du fil de bobinage en cuivre enveloppé chauffé par création d'au moins un vide partiel à l'intérieur du tube. Le procédé comprend le ré-étirage du fil de bobinage en cuivre enveloppé à travers un moule d'extrusion après que l'humidité a été éliminée. Le procédé comprend l'application de PEEK fondu sur le fil de bobinage en cuivre enveloppé pour produire un fil de bobinage amélioré, et l'enroulement du fil de bobinage amélioré dans un moteur à induction.
