An electric machine includes a stator and a rotor core including a first rotor portion positioned adjacent the stator and having an outside diameter. The first rotor portion includes a plurality of elongated slots that define a plurality of poles. The electric machine also includes a plurality of magnets. Each of the plurality of magnets is positioned within one of the slots and ar-ranged such that each of the plurality of poles has a magnetic arc length that is different than a magnetic arc length of any adjacent pole.
L'invention porte sur une machine électrique qui comprend un stator et un noyau de rotor comprenant une première partie de rotor positionnée de façon adjacente au stator et ayant un diamètre externe. La première partie de rotor comprend une pluralité de fentes allongées qui définissent une pluralité de pôles. La machine électrique comprend également une pluralité d'aimants. Chacun de la pluralité d'aimants est positionné à l'intérieur de l'une des fentes et agencé de telle sorte que chacun de la pluralité de pôles a une longueur d'arc magnétique qui est différente de la longueur d'arc magnétique d'un quelconque pôle adjacent.
