Patent ID: 8278785

Claim:
An electromagnetic linear motor comprising: a longitudinal stator comprising: a cylindrical hollow stator body made of a magnetically soft material and having a first end, a first segment extending from the first end, a second end facing away from the first end, a second segment extending from the second end, and a third segment directly connected to the first segment and directly connected to the second segment, a hollow space running axially through the cylindrical hollow stator body, and a single magnetic coil connected to the cylindrical hollow stator body on an inside of the cylindrical hollow stator body facing the hollow space, the single magnetic coil having windings including an electrical conductor of the hollow space, and at least one rotor linearly movable in the stator and comprising an axially magnetized permanent magnet, wherein the first segment and the second segment of the cylindrical hollow stator body limit an equally large or differing cross section of the hollow space, wherein the third segment extends into the hollow space, wherein all cross sections of the hollow space limited by the cylindrical hollow stator body in the third segment are smaller than all of the cross sections of the hollow space in the first segment and are smaller than all of the cross sections of the hollow space in the second segment, wherein the single magnetic coil is the sole magnetic coil connected to the cylindrical hollow stator body on the inside of the cylindrical hollow stator body, and wherein the third segment is the sole segment directly connected to the first and second segments that extends into the hollow space.
