Abstract
An MSM actuator system, comprising at least one expansion unit (22) having a magnetic shape memory material (MSM); coil means (27) for creating the magnetic flux; and flux-conducting means (10 to 16) made from a magnetically conductive material, the flux-conducting means constructed for enclosing by means of the coil means and magnetically flux-conducting contacting of the expansion unit by means of mutually opposite end sections (18, 20).
Claims14
An MSM actuator system, comprising:
- at least one expansion unit (22) having a magnetic shape memory material (MSM) constructed for controlling interaction with an external control partner by executing an expansion movement as a reaction to an introduced magnetic flux;
- coil means (27) for creating the magnetic flux, which is adapted to be switched and fed with current;
- and
- flux-conducting means (10 to 16) made from a magnetically conductive material assigned to both the coil means and the at least one expansion unit, the flux-conducting means are constructed for magnetically flux-conducting contacting of the expansion unit by means of mutually opposite end sections (18, 20), wherein the flux-conducting means have a plurality of flux-conducting bows (10 to 16), which are structured structurally identically to one another and in each case have a winding section guidable through a winding (29) provided on a coil carrier of the coil means, a pair of opposite end sections (18, 20) as open shank of the respective flux-conducting bow and also a magnetically flux-conducting contact section for contacting an adjacent contact section of an adjacent flux-conducting bow, wherein the contact section allows at least one of a stacking of the plurality of flux-conducting bows along the direction of the expansion movement and a stacking of the plurality of flux-conducting bows by at least some of a plurality of contact sections.
