Abstract

L'invention concerne une machine électrique synchrone sans balais et sans aimants caractérisée en ce qu'elle comprend un stator (20) comprenant un anneau (22), un bobinage (28) et une denture (24) comprenant des dents (26) s'étendant parallèlement à l'axe de rotation à partir de l'anneau (22), ledit bobinage étant enroulé autour de la denture (24), un rotor (10), comprenant une première partie (12a) s'étendant selon p directions (18a) privilégiées, une deuxième partie (12b) s'étendant selon p direction (18b) privilégiée décalées de π/p par rapport aux directions privilégiées de la première partie (18a), et une partie (14) intermédiaire reliant la première partie (12a) à la deuxième partie (12b), et une bobine (40) d'excitation du rotor, fixe par rapport au stator, alimentée par un courant électrique continu, disposée autour de la partie (14) intermédiaire du rotor et configurée pour générer un flux électrique dans le rotor (10) par induction magnétique.
