Electrical linear machine

An electrical linear machine, comprising:

• an armature that is axially displaceable relative to a housing, and that includes a permanent magnet having a magnetic north pole and a magnetic south pole;
• and
• a stator that is fixed to the housing, and that includes:
• a first stator yoke that has a first pair of stator poles;
• and
• a second stator yoke that has a second pair of stator poles, the second stator yoke rotationally offset from the first stator yoke such that the first and second pairs of stator poles are distributed radially and uniformly around the armature,
• wherein:
• only the first stator yoke includes at least one coil configured to be energized;
• and
• energizing the at least one coil generates a first magnetic flux through the first stator yoke and the permanent magnet, and
• wherein the permanent magnet is fixed at an orientation such that the magnetic north pole of the permanent magnet is facing toward a first stator pole of the second pair of stator poles, and such that the magnetic south pole of the permanent magnet is facing toward a second stator pole of the second pair of stator poles, so that the permanent magnet generates a second magnetic flux through the second stator yoke.
