Abstract :
For minitype thermoacoustic Stirling systems, a new configuration of miniature moving magnetic linear actuator has been designed and tested by experiment. Then the expression of the electromagnetic force against the input current was deduced by the magnetic circuit analysis and verified by experimental investigations. The maximum displacement of the actuator is 5mm and its peak force obtained is 244N.
