Les dents de stator sont connectées à demeure en couches dans la direction de l'axe de rotation. Chaque dent de stator est constituée d'un noyau de fer de dent de stator (0231) et d'une bobine de dent de stator (0232) gainée extérieurement. Une paire d'extrémités du noyau de fer de dent de stator et de dent de rotor qui forment un entrefer sont des surfaces arquées s'emboîtant l'une dans l'autre de manière concave-convexe. La relation de coopération entre la dent de stator et la dent de rotor est telle que, quel que soit l'angle suivant lequel la dent de rotor tourne par rapport à la dent de stator, une ligne centrale d'au moins une couche de dent de stator et une ligne centrale de dent de rotor d'une unité correspondante de dent de rotor forment un angle inclus α, 0 ＜ α ≤ β, β étant un angle d'arc de cercle, par rapport au centre du cercle, d'une section transversale du noyau de fer de dent de stator ou de dent de rotor dans la direction de l'axe de rotation.
