In recent years, Stirling Dish designs and applications for obtaining electrical energy from solar energy have attracted attention. In this system, electrical energy can be obtained directly without the need for an additional mechanical transformation. It can be provided by placing a linear generator in the free piston mechanism. In terms of power density, permanent magnet tube type generators are preferred for these applications. The studies carried out on this field of study in the literature have been examined in general terms. The numerical analysis of the tube type linear generator, whose analytical design has been realized, has been discussed. Numerical analyzes have been performed using Ansys Maxwell software. In addition to obtaining the output data of the generator, cost analysis has also been performed. The analysis results at different operating frequency values ​​have also been examined.
