<p>An electromechanical transducer particularly useful as a linear alternator driven by a free-piston Stirling engine. A relatively high permeability material (20, 22) is formed into a flux loop having at least a pair of spaced gaps (24, 26) formed transversely through the loop. The gaps are aligned along a reciprocation path for a magnet which is mechanically mounted for reciprocation between alternate positions within the gaps. The magnet (30) has a magnetization vector transverse to the reciprocation path and is drivingly linked to a mechanical energy input or output for operation respectively as an alternator or motor. The armature coil (28) is wound around a portion of the flux loop.</p> |
