Abstract:
An electrical linear machine includes a stator that is fixed to a housing and an armature that is configured to be axially displaced and supports a permanent magnet. The stator has a first stator yolk and a second stator yoke with the stator yolks each forming a stator pole. The stator poles are arranged in a manner distributed radially and uniformly around the armature. The first stator yoke is associated with at least one coil to which current is applied so as to generate a first magnetic flux through the first stator yoke and the permanent magnet. A magnetic north pole of the permanent magnet is associated with a stator pole of the second stator yoke and a magnetic south pole of the permanent magnet is associated with the other stator pole of the second stator yoke in order to generate a second magnetic flux through the second stator yoke.
