This work presents experimental study on pneumatic actuated meso-scale permanent magnet power generator. It aims at generating electrical power by spinning a rotor carrying permanent magnets at low rotational speeds to induce current in conducting windings set in a stator in close proximity below the magnets. A number of miniaturized generators were manufactured and tested under different parameters, including: number of winding turns, conducting wire size, number of inserted permanent magnets into the rotor, and spinning speed. In addition, the effect of inserting back-iron to the stator onto output power generation was investigated. The generator was tested experimentally and showed that it can generate milliwatt to watt level power. These investigations have demonstrated the feasibility and scalability of magnetic devices for power generating applications. The generator delivered a power of 1.45 W at resistive load of 30 Ω and spinning speed of 6000 rpm.
