ABSTRACT:
A linear actuator is provided with an armature and a stator. The armature has at least two stacks of permanently magnetic rods one over another, the stacks being arranged at a predetermined distance from each other. The stator is at least partly produced from a soft magnetic material, and comprises at least two pairs of teeth with teeth opposite each other, each pair of teeth receiving one of the two stacks between them while forming an air gap. The stator has at least two magnetically conducting inner areas which are located between the two stacks and arranged at a predetermined distance from each other in the direction of motion of the armature. The inner areas are each at least partially surrounded by a substantially hollow cylindrical coil arrangement, the central longitudinal axis of which is oriented substantially transversely to the direction of motion of the armature.
