<p>The linear motor has a stator (1) with permanent magnets (7, 8) magnetically connected with each other by a return element (10). A coil (9) is arranged between the permanent magnets. A rotation symmetric rotor (2) is displaced parallel to the stator and includes a hollow cylindrical yoke (3), which is arranged on a side of the stator, where the side faces away from the return element. The yoke magnetically engages with the magnets. An optical element e.g. lens, is placed inside the yoke. The magnets are arranged within an intermediate space between pole shoes (4, 5).</p> |
