The free piston thermoacoustic Stirling power generation technology is a new type of thermal power generation technology. The generator developed based on this technology mainly consists of two parts: a free piston thermoacoustic engine and a linear motor. The main components of the engine include a heater, a thermoacoustic transducer (traditionally referred to as a reheater), a cooler, etc. The main components of a linear motor are the power piston, permanent magnet, coil, etc.
