Abstract
An alpha type Stirling engine is provided and comprises an expansion cylinder and a compression cylinder, a regenerator, a cooler, and a heater. Each one of the expansion cylinder and the compression cylinder has a movable piston connected to a respective linear electric generator/motor, wherein the Stirling engine further comprises a control unit which is operatively connected to the linear electric generators/motors and which is configured to control the linear electric generators/motors individually so as to enable a different stroke length and/or motion profile of the piston in the expansion cylinder compared to the piston in the compression cylinder.
