Abstract:
(EN) The present invention relates to a rotating electric device such as an electric motor, a generator, or the like. The present invention provides a rotating electric device comprising: an outer stator (210) comprising an outer stator iron core (211) having a plurality of outer stator winding slots (213) formed on the inner peripheral surface thereof at a predetermined interval in the circumferential direction, and an outer winding (510) wound around an outer stator iron core tooth (218) relatively formed by a pair of outer stator winding slots (213) adjacent to each other; an inner stator (220) comprising an inner stator iron core (221) having a plurality of inner stator winding slots (223) formed on the outer peripheral surface thereof at a predetermined interval in the circumferential direction; and a rotor (300) having, between the outer stator (210) and the inner stator (220), a first gap (610) with regard to the outside and a second gap (620) with regard to the inside, the rotor (300) having a plurality of rotor iron cores (340) and a plurality of permanent magnets (330) installed to be able to rotate, the permanent magnets (330) being coupled between the rotor iron cores (340) along the circumferential direction. The outer stator iron core (211) has at least one outer stator iron core slot (212) formed on the inner peripheral surface thereof to be concave between a pair of outer stator winding slots (213) adjacent to each other. The inner stator iron core (221) has at least one inner stator iron core slot (222) formed on the outer peripheral surface thereof to be concave between a pair of inner stator winding slots (223) adjacent to each other.
(FR) La présente invention concerne un dispositif électrique tournant tel qu'un moteur électrique, une génératrice ou similaire. La présente invention porte sur un dispositif électrique tournant comprenant : un stator externe (210) comprenant un noyau de fer de stator externe (211) comportant une pluralité d'encoches d'enroulement de stator externe (213) formées sur sa surface périphérique interne à intervalle prédéterminé dans la direction circonférentielle, et un enroulement externe (510) enroulé autour d'une dent de noyau de fer de stator externe (218) relativement formée par une paire d'encoches d'enroulement de stator externe (213) adjacentes l'une à l'autre ; un stator interne (220) comprenant un noyau de fer de stator interne (221) comportant une pluralité d'encoches d"enroulement de stator interne (223) formées sur sa surface périphérique externe à intervalle prédéterminé dans la direction circonférentielle ; et un rotor (300) présentant, entre le stator externe (210) et le stator interne (220), un premier entrefer (610) par rapport à l'extérieur et un second entrefer (620) par rapport à l'intérieur, le rotor (300) comportant une pluralité de noyaux de fer de rotor (340) et une pluralité d'aimants permanents (330) installés pour pouvoir tourner, les aimants permanents (330) étant couplés entre les noyaux de fer de rotor (340) le long de la direction circonférentielle. Le noyau de fer de stator externe (211) comporte au moins une encoche de noyau de fer de stator externe (212) formée sur sa surface périphérique interne pour être concave entre une paire d'encoches d'enroulement de stator externe (213) adjacentes l'une à l'autre. Le noyau de fer de stator interne (221) comporte au moins une encoche de noyau de fer de stator interne (222) formée sur sa surface périphérique externe pour être concave entre une paire d'encoches d'enroulement de stator interne (223) adjacentes l'une à l'autre.
