HIGH POWER DENSITY MOTOR HAVING BRIDGED SPOKED ROTOR AND PREWOUND BOBBINS FOR STATOR
(FR)
MOTEUR À PUISSANCE VOLUMIQUE ÉLEVÉE COMPORTANT UN ROTOR À RAYONS PONTÉS ET DES BOBINES PRÉENROULÉES POUR STATOR
Abstract:
(EN)
A motor includes a stator and a rotor. The rotor is rotatable about an axis. The rotor includes a core including a plurality of pole segments arranged arcuately about the axis. The rotor further includes a plurality of arcuately arranged magnets alternating arcuately with the pole segments, such that each of the magnets is at least in part interposed between a pair of adjacent pole segments. The plurality of pole segments includes a plurality of first-polarity pole segments having a first polarity and a plurality of second-polarity pole segments having a second polarity that is different than the first polarity. The rotor further includes a connecting element connecting at least some of the first-polarity pole segments to one another without connecting the second-polarity pole segments to the first-polarity pole segments.
(FR)
L'invention concerne un moteur comprenant un stator et un rotor. Le rotor peut tourner autour d'un axe. Le rotor comprend un noyau comprenant une pluralité de segments polaires disposés en arc autour de l'axe. Le rotor comprend en outre une pluralité d'aimants disposés en arc alternant de manière arquée avec les segments polaires, de telle sorte que chacun des aimants est au moins en partie intercalé entre une paire de segments polaires adjacents. La pluralité de segments polaires comprend une pluralité de segments polaires de première polarité ayant une première polarité et une pluralité de segments polaires de deuxième polarité ayant une deuxième polarité qui est différente de la première polarité. Le rotor comprend en outre un élément de connexion connectant au moins certains des segments polaires de première polarité les uns par rapport aux autres sans connecter les segments polaires de deuxième polarité aux segments polaires de première polarité.
