An electrical machine with at least a machine unit. This machine unit includes a stator, which includes a plurality of magnetic flux conductors, an electric conductor forming a winding extending in a substantially closed winding path through each magnetic flux conductor, and a least one first movable element, which includes a number of permanent magnet elements 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 formed by at least some of the magnetic flux conductors. The winding path includes a first current carrying portion, which extends substantially in parallel with the first movement path. Each magnetic flux conductor is arranged to form, together with one of the permanent magnetic elements, a closed magnetic flux circuit extending around the current carrying portion.

Each magnetic flux conductor is arranged to form, together with one of the permanent magnet elements, a closed magnetic flux circuit extending around the current carrying portion. The magnetic flux conductors are arranged in an alternating order with respect to the direction of the magnetic flux in relation to the permanent magnet elements in the respective magnetic flux circuit.
