<p>The invention refers to an electrical machine with at least a machine unit (1). This machine unit includes a stator, which includes a plurality of magnetic flux conductors (3', 3') and an electric conductor forming a winding extending in a substantially closed winding path through each magnetic flux conductor, and at least one first movable element (10), which includes a number of permanent magnet elements (12', 12') 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 said magnetic flux conductors. The winding path includes a first current carrying portion (6a), which extends substantially in parallel with the first movement path. Each magnetic flux conductor (3', 3') is arranged to form, together with one of said permanent magnet elements (12', 12'), a closed magnetic flux circuit extending around said current carrying portion.</p> |
