Abstract
A linear motor for optical systems, for example, endoscopes, is described. The motor has a stator with a magnetic guiding member and a coil. The armature of the motor includes two permanent magnets which are of opposite polarity. A pole piece made of soft-magnetic material is provided between the permanent magnets. By applying current to the coil, the armature can be displaced from a rest position in the longitudinal direction.
