Title (EN) DESIGN OF STATOR AND ROTORS OF INTERNAL ROTOR AC SQUIRREL CAGE ELECTRIC MOTORS AND WINDING
(FR) CONCEPTION DE STATOR ET DE ROTORS DE MOTEURS ÉLECTRIQUES À CAGE D'ÉCUREUIL À COURANT ALTERNATIF (CA) À ROTOR INTERNE ET D'ENROULEMENT
Abstract:
(EN) The present invention relates to a squirrel cage motor, comprising:a stator;a rotor core rotatably disposed axially in the stator; the rotor core having a first end face and a second end face; and a plurality of longitudinal slots radially disposed along a circumference of the rotor core at an interval and a plurality of conductor bars housed in the longitudinal slots; and a pair of coaxial end rings abutting each of the first end face and the second end face of said rotor such that the cross-sectional area of coaxial ringdistalto the axis has a cross section smaller than the coaxial ring proximal from the axis.
(FR) La présente invention concerne un moteur à cage d'écureuil, comprenant : un stator ; un noyau de rotor disposé de manière rotative axialement dans le stator ; le noyau de rotor ayant une première face d'extrémité et une seconde face d'extrémité ; et une pluralité de fentes longitudinales disposées radialement le long d'une circonférence du noyau de rotor à un intervalle et une pluralité de barres conductrices logées dans les fentes longitudinales ; et une paire d'anneaux d'extrémité coaxiaux venant en butée contre chacune de la première face d'extrémité et de la seconde face d'extrémité dudit rotor de telle sorte que la zone de section transversale de l'anneau coaxial à distance de l'axe a une section transversale plus petite que l'anneau coaxial à proximité de l'axe.
