Abstract

In this research, the variation of electrical power according to the temperature in Stirling motors was analyzed. The performance characteristics of a low power Beta type Stirling motor were determined in the situation of working gas becoming air gas in this research, Results were compared and are presented graphically. Performance tests of a Stirling motor heated by thermal specifications of the sun were made at heater temperatures of 673 K, 773 K and 873 K. Also, an electrical power increase was provided by raising the temperature difference between the hot edge of the displacer and cooler temperatures.
