摘要: This paper presents a novel micro-power conversion device that combines an axial flow turbine with axial-flux electromagnetic generator. The has sandwich structure, consisting of top silicon stator, polymer rotor and bottom stator. Axial gas through the causes rotation, while permanent magnets embedded in induce output voltage planar coils on stators. Compared to radial devices axial-flow design is more compact can operate at lower pressure ratios. Details fabrication process are given, preliminary results presented for variation voltage, rotation speed, ratio rate nitrogen gas. test show operation over wide dynamic range.
