Linear alternators are frequently proposed and used as electric energy producing devices in connection with free-piston Stirling engines.

The objective of this paper is to provide a mathematical model able to describe a free-piston Stirling engine/linear alternator combination as a whole system, where the thermodynamic and the electrodynamic aspects are linked together.

Abstract

Linear alternators are frequently proposed and used as electric energy producing devices in connection with free-piston Stirling engines. However, whilst considerable research work has been done on this type of engine and on its dynamics and thermodynamics, there are only few studies dealing with the linear alternator and its interaction with both the engine and the load. The objective of this paper is to provide a mathematical model able to describe a free-piston Stirling engine/linear alternator combination as a whole system, where the thermodynamic and the electrodynamic aspects are linked together. In particular the method is applied: to calculate the force resisting the piston motion produced by the alternator and the associated load; to derive an electrodynamic steady condition for the system steady operation; to find a condition which ensures the maximum power transfer from the engine/alternator system to the connected load.
