VARIABLE RELUCTANCE ACTUATOR
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 singl...

Zusammenfassung: | 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). |
