PROVIDING ELECTRICAL POWER INCREASE BY STIMULATING TEMPERATURE DIFFERENCE AT LOW TEMPERATURES IN STIRLING MOTORS

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.
