Design of a 1kW class gamma type Stirling engine

The study for a design on a kinematic drive gamma type Stirling engine is reported. This unity enters in the 1 kW class and it is conceived to move a portable electric generator. The peculiarity of this unity is basically to use components taken from the line production. And also for what concerns the parts designed novelty all the efforts are directed to the simplicity in terms of material and manufacture. At first the engine targets are defined in compatibility with the elements taken from a large scale production compressor and then the new components like the heat exchangers and the crank mechanism are designed. Two pre-tests are effected: one to define the performances of the induction motor in the electric regenerative mode and another running the machine as a refrigerator.
