Abstract

An electromagnetic linear motor is proposed that features a longitudinal stator, a hollow body of the stator made of a magnetically soft material, a magnetic coil of the stator, a rotor in the stator that is movable linearly relative to the magnetic coil, an axially magnetized permanent magnet of the rotor and an axially variable shape or variable magnetic material properties of the stator.
