Title (EN) COMPRESSOR
(FR) COMPRESSEUR
Abstract:
(EN) The invention relates to a compressor for refrigerant having a compressor housing, said compressor housing being provided with a suction inlet and a pressure outlet, said compressor comprising a compression unit, arranged in a compression housing section of said compressor housing and an electric motor arranged in a motor housing section of said compressor housing, said electric motor comprising a stator arranged within a stator receiving sleeve of said motor housing section and a rotor surrounded by said stator and arranged on a drive shaft of said electric motor for rotation about an axis of rotation together with said drive shaft, said stator comprising a stator core having a stack of laminations and extending parallel to said axis of rotation from a first front side to a second front side, said stator having windings extending through said stator core and forming end windings arranged in front of said front surfaces, and a channel for guiding at least a portion of said refrigerant entering through said suction inlet along an outer side of said stator before entering said compression unit.
(FR) L'invention concerne un compresseur pour réfrigérant ayant un carter de compresseur, ledit carter de compresseur étant pourvu d'un orifice d'aspiration et d'un orifice de sortie sous pression, ledit compresseur comprenant une unité de compression, disposée dans une section carter de compression dudit carter de compresseur et un moteur électrique disposé dans une section carter de moteur dudit carter de compresseur, ledit moteur électrique comprenant un stator disposé à l'intérieur d'un manchon de réception de stator de ladite section carter de moteur et un rotor entouré par ledit stator et disposé sur un arbre d'entraînement dudit moteur électrique pour tourner autour d'un axe de rotation conjointement avec ledit arbre d'entraînement, ledit stator comprenant un noyau de stator présentant une pile de stratifications et s'étendant parallèlement audit axe de rotation à partir d'un premier côté avant vers un second côté avant, ledit stator ayant des enroulements s'étendant à travers ledit noyau de stator et formant des enroulements d'extrémité disposés en face desdites faces avant, et un canal pour guider au moins une partie dudit réfrigérant entrant par ledit orifice d'aspiration le long d'un côté externe dudit stator avant d'entrer dans ladite unité de compression.
