Infinia is developing the next generation of space‐ready Stirling Convertor Assemblies. Infinia has previously proposed a Low‐Mass Stirling Convertor Assembly (SCA) design employing a flux‐concentrating, moving‐iron linear alternator. This paper describes further development of that proposed machine, including additional improvements and advancements. One significant change is a new, lighter‐weight moving‐magnet alternator design. Infinia has shown progress in the low mass design’s development and testing: namely in the area of flexure spring rates, welding techniques on the flange, and a change to the alternator configuration. Progress has been made with the flat‐top heater head design and its capabilities, as well. The changes described in this paper will significantly reduce the mass and increase the power density of the low‐mass design.
