Electrical machine

An electrical machine operating according to the transversal including at least one first machine unit, which comprises:

• a stator, which includes a plurality of magnetic flux conductors and an electric conductor forming a winding extending in a substantially closed winding path through each magnetic flux conductor;
• a first movable element, which includes a number of permanent magnet elements provided in a rod-like configuration and which is movable in a reciprocating movement in relation to the stator along a first movement path in a space having a finite length and being formed by at least some of said magnetic flux conductors;
• a second movable element, which includes a number of permanent magnet elements provided in a rod-like configuration, and which is movable in a reciprocating movement in relation to the stator along a second movement path extending in parallel with the first movement path,
• wherein the substantially closed winding path includes a first current carrying portion, which extends substantially in parallel with the first movement path, and a second current carrying portion, which extends substantially in parallel with the second movement path,
• wherein the first current carrying portion of the winding path is associated substantially with a first half of said magnetic flux conductor, and the second current carrying portion of the winding path is associated substantially with a second half of said magnetic flux conductor,
• wherein the magnetic flux conductors of said first half is arranged to form, together with one of said permanent magnet elements of said first movable element, a closed magnetic flux circuit extending around said first current carrying portion,
• wherein each magnetic flux conductor of said second half is arranged to form, together with one of said permanent magnet elements of said second movable element, a close magnetic flux circuit extending around said second current carrying portion,
• wherein the magnetic flux conductors are arranged in an alternating order with respect to a direction of the magnetic flux in relation to the permanent magnet elements in the respective magnetic flux circuit, and wherein each magnetic flux circuit includes a first gap between a first pole of the permanent magnet elements of the circuit and an end surface of the magnetic flux conductor of the circuit, and a second gap between a second pole of the permanent magnet elements of the circuit and a second end surface of the magnetic flux conductor of the circuit.
