Title (EN) ELECTRIC MOTOR
(FR) MOTEUR ÉLECTRIQUE
(DE) ELEKTROMOTOR
Abstract:
(EN) The invention relates to an electric motor (20), in particular for an electric refrigerant drive (2), comprising a motor housing (18a), in which a stator (28) and a rotor (26) rotatably mounted with respect to the latter are accommodated, wherein the stator (28) has a cylindrical stator yoke (60), from which, starting on the inner circumferential side, a number of stator teeth (54) extend radially inward in a star shape, a circular ring-shaped gap region (68) is formed between the outer circumference (66) of the stator yoke (60) and the inner circumference (64) of the motor housing (18a), and wherein a damping intermediate layer (17) is introduced into the gap region (68).
(FR) L'invention concerne un moteur électrique (20), en particulier pour un système d'entraînement électrique pour réfrigérant (2). Le moteur comprend un carter (18a), dans lequel sont logés un stator (28) ainsi qu'un rotor (26) monté en rotation par rapport à celui-ci, le stator (28) présentant une culasse (60) cylindrique, de laquelle une pluralité de dents (54) de stator s'étendent radialement vers l'intérieur en forme d'étoile côté périphérie intérieure. Une zone de fente circulaire (68) est formée entre la périphérie extérieure (66) de la culasse (60) du stator et la périphérie intérieure (64) du carter (18a) du moteur, et une couche intermédiaire d'amortissement (70) est introduite dans la zone de fente (68).
(DE) Die Erfindung betrifft einen Elektromotor (20), insbesondere für einen elektrischen Kältemittelantrieb (2), mit einem Motorgehäuse (18a), in welchem ein Stator (28) sowie ein gegenüber diesem drehbar gelagerter Rotor (26) aufgenommen sind, wobei der Stator (28) ein zylinderförmiges Statorjoch (60) aufweist, von dem sich innenumfangsseitig ausgehend eine Anzahl von Statorzähnen (54) sternförmig radial einwärts erstrecken, wobei zwischen dem Außenumfang (66) des Statorjochs (60) und dem Innenumfang (64) des Motorgehäuse (18a) ein kreisringförmiger Spaltbereich (68) gebildet ist, und wobei in den Spaltbereich (68) eine dämpfende Zwischenschicht (70) eingebracht ist.
