Title (EN) VARIABLE RELUCTANCE ACTUATOR
(FR) ACTIONNEUR À RÉLUCTANCE VARIABLE
Abstract:
(EN) A variable reluctance actuator (1) comprises: - a stator having a stator core (2) comprising a single stator salient pole (7) with a single coil winding (4); - a rotor having a rotor core (3) rotatable around an axis of rotation (R) between a start position and an end position and comprising a single rotor salient pole (8); - a shaft (6) integrally rotatable with the rotor core (2), wherein an air gap (9) is formed between the rotor salient pole (8) and the stator salient pole (7) when the rotor core (3) moves between the start and the end positions, the stator salient pole (7) and the rotor salient pole (8) being shaped such that the radial distance between a same point on the rotor salient pole (8) and the stator salient pole (7) at the air gap (9) varies as a function of the angular position of the rotor core (3).
(FR) Cette invention concerne un actionneur à réluctance variable (1) comprenant : - un stator ayant un noyau de stator (2) comprenant un unique pôle saillant de stator (7) avec un unique enroulement de bobine (4) ; - un rotor ayant un noyau de rotor (3) pouvant tourner autour d'un axe de rotation (R) entre une position de départ et une position finale et comprenant un unique pôle saillant de rotor (8) ; - un arbre (6) pouvant tourner d'un seul tenant avec le noyau de rotor (2), un entrefer (9) étant formé entre le pôle saillant de rotor (8) et le pôle saillant de stator (7) lorsque le noyau de rotor (3) se déplace entre les positions de départ et finale, le pôle saillant de stator (7) et le pôle saillant de rotor (8) étant profilés de telle sorte que la distance radiale entre un même point sur le pôle saillant de rotor (8) et le pôle saillant de stator (7) au niveau de l'entrefer (9) varie en fonction de la position angulaire du noyau de rotor (3).
