Abstract

The invention relates to a thrust actuator for converting a continuous, that is, cyclically recurring, rotational movement to a discontinuous thrust movement of a permanent-magnet rotor magnet, and to a Stirling engine which particularly benefits therefrom. According to the invention, the rotor magnet is movably mounted such that it can be displaced toward a drive magnet, wherein the polarity of the drive magnet relative to the rotor magnet can be varied by the rotational movement. The rotor magnet can be connected in particular to a rotor which participates in the thrust movement of the rotor magnet. It was recognized that the continuous rotational movement modulates the magnetic interaction between the rotor magnet and the drive magnet periodically between attraction and repulsion in said arrangement. The rotor magnet can thus be moved periodically but abruptly away from and back toward the drive magnet. A discontinuous, periodic thrust movement of the rotor magnet and of a rotor that may be coupled thereto can thus be achieved. The invention further relates to a Stirling engine as a primary application for the thrust actuator.
