Abstract

Le turbocompresseur (1) comporte un arbre d'entraînement (3) ; au moins un rouet (7.1) relié à une première partie d'extrémité axiale (4) de l'arbre d'entraînement (3) ; un moteur électrique (12) comportant un stator de moteur (13) et un rotor de moteur (14), le rotor de moteur (14) étant relié à une deuxième partie d'extrémité axiale (5) de l'arbre d'entraînement (3) ; un espacement annulaire de moteur (16) défini entre le stator de moteur (13) et un ensemble rotor formé par l'arbre d'entraînement (3) et le rotor de moteur (14) ; un agencement de refroidissement de moteur configuré pour refroidir le moteur électrique (12) avec un flux de fluide frigorigène. L'agencement de refroidissement de moteur est agencé de sorte que, pendant le fonctionnement du turbocompresseur (1), le flux de fluide frigorigène entre dans l'espacement annulaire de moteur (16) au niveau d'une première extrémité du moteur électrique (12) tournée vers l'au moins un rouet (7.1) et quitte l'espacement annulaire de moteur (16) au niveau d'une deuxième extrémité du moteur électrique (12) opposée à la première extrémité du moteur électrique (12).The turbocharger (1) has a drive shaft (3); at least one impeller (7.1) connected to a first axial end part (4) of the drive shaft (3); an electric motor (12) having a motor stator (13) and a motor rotor (14), the motor rotor (14) being connected to a second axial end portion (5) of the drive shaft (3); a motor annular gap (16) defined between the motor stator (13) and a rotor assembly formed by the drive shaft (3) and the motor rotor (14); an engine cooling arrangement configured to cool the electric motor (12) with a flow of refrigerant. The engine cooling arrangement is arranged so that, during operation of the turbocharger (1), the flow of refrigerant enters the engine annular gap (16) at a first end of the electric motor (12). ) facing towards the at least one impeller (7.1) and leaves the motor annular gap (16) at a second end of the electric motor (12) opposite the first end of the electric motor (12).
