Electromechanical transducer particularly suitable for a linear alternator driven by a free-piston Stirling engine
This patent describes an electromechanical transducer comprising: (a) a flux loop member which is stationary relative to the below described magnets. The member is formed of a relatively high permeability material the flux loop member having at least two pairs of spaced gaps formed transversely through the loop member to provide at least two pairs of gaps in each flux loop. Each pair of gaps aligned along a reciprocation path; (b) an armature coil wound about the loop member; and (c) at least two magnets each mechanically mounted for reciprocation along the reciprocation path for a different one of the pairs of gaps to alternate positions within the gaps of each pair. The magnets have a magnetization vector transverse to their reciprocation paths and across the gap and drivingly linked to a mechanical energy input or output.
