The thermodynamic efficiency of the stirling engine has a high theoretical efficiency closest to that of the Carnot cycle, and various heat sources can be used as an external combustion engine. In the early days of the invention, the sealing technology was not good, so it was pushed to the steam engine and was not put to practical use, and in modern times, it was not used due to the development of internal combustion engines. Sterling cryogenic refrigerators using linear compressors have advantages such as low vibration, small size, light weight, low required power, and sufficient durability compared to conventional cryogenic refrigerators, so they are widely used as infrared sensors for night vision goggles (0.5 to 1.9 W at 77 K) and superconducting filters for mobile communication wireless base stations (3 to 6 W at 77 K). By examining the characteristics of the refrigerator using such a stirling refrigerant refrigerator, the difference from the existing refrigeration air conditioning system using refrigerant gas can be seen, and this study showed that the manufacturing method of the motor part and the design of the inlet voltage and current and frequency of the motor greatly affect the performance of small linear stirling refrigerators when manufacturing a compressor of a linear stirling refrigerator.
