An electrical machine with at least a machine unit. The machine unit includes 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, and a movable element, which includes permanent magnet elements movable in a reciprocating movement in relation to the stator along a movement path. The winding path includes a first current carrying portion, which extends substantially in parallel with the movement path. 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.
