A reluctance machine includes a stator having a stator core. The stator core includes a central bore and a plurality of stator poles (30) extending inwardly from the stator core. Each of the stator poles (30) includes a stator pole face (38). The reluctance machine further includes a rotor having a plurality of rotor poles (62). Each of the rotor poles includes a rotor pole face (78). Each of the rotor pole faces includes a first portion (78a), a second portion (78b) that is radially inwardly stepped with respect to the first portion to create a non-uniform air gap (80) between the rotor pole face (78) and a corresponding stator pole face (38), and a protrusion (82) located at an edge of the second portion (78b) of the rotor pole face (78).
La présente invention concerne une machine à reluctance qui comprend un stator ayant un noyau de stator. Le noyau de stator comprend un alésage central et une pluralité de pôles de stator (30) s~étendant vers l~intérieur depuis le noyau de stator. Chacun des pôles de stator (30) comprend une face de pôle de stator (38). La machine à reluctance comprend en outre un rotor présentant une pluralité de pôles de rotor (62). Chaque pôle de rotor comprend une face de pôle de rotor (78). Chaque face de pôle de rotor comprend une première partie (78a), une seconde partie (78b) qui est radialement étagée vers l~intérieur par rapport à la première partie afin de créer un entrefer non uniforme (80) entre la face de pôle de rotor (78) et une face de pôle de stator correspondante (38), et une saillie (82) située au niveau d~un bord de la seconde partie (78b) de la face de pôle de rotor (78).
