The document discussed the design and analysis of micro-turbogenerators, focusing on the scaling laws affecting turbomachinery and permanent magnet generators. It highlighted challenges such as efficiency and power transfer capabilities, noting that single-stage reaction turbines offered the best efficiency and power density at small scales, albeit requiring higher angular velocities. The study showed that permanent magnet generators had higher power densities at small sizes. A 3-phase multi-layer permanent magnet generator was designed, achieving efficiencies of 64% and 93% with improved designs. Additionally, an ejector-driven turbogenerator was tested, producing a DC power output of 7.5 mW at 27,360 RPM.
