ROTOR DE MACHINE ELECTRIQUE TOURNANTE EQUIPE D'UNE FRETTE

Ce rotor (10) de machine électrique tournante comporte un moyeu (12), des éléments actifs périphériques (14) rapportés à la périphérie du moyeu (12) et une frette (16) ceinturant les éléments actifs périphériques (14) et le moyeu (12). La frette (16) comporte des fibres de poly-para-phénylène téréphtalamide noyées dans une matrice de polyétheréthercétone. The rotor (10) has peripheral active elements i.e. magnetic bars (14), fixed at the periphery of a central hub (12), and a binding band (16) surrounding the peripheral active elements and the hub, where the binding band is in the form of a cylindrical sleeve. The binding band comprises 60 mass percentage of reinforcement fibers e.g. glass fibers, carbon fibers or poly-para-phenylene terephthalamide fibers that are drowned in a polyetheretherketone (PEEK)(RTM: colorless organic polymer thermoplastic) matrix. The binding band has thickness that ranges from 3 to 20 mm. An independent claim is also included for a method for fabricating a rotor of an electrical rotating machine.
