This study proposes a simply fabricated micro stator for higher output power than previously reported micro stators. The stator hasbeen fabricated by inserting enamel coil in silicon mold formed by micro etching process. The most merits of the proposed micro statorare the simple fabrication process and high output power. Previously reported micro stators have high resistance because the micro coil isfabricated by relatively thin-film-based deposition process such as sputtering and electroplating. In addition, the previously reported microcoil has many electrical contact points for forming the coil structure. These characteristics of the micro stator can lead to low performancein output power. However, the proposed micro stator adopts commercially available enamel coil without any contact point. Therefore, theenamel coil of the proposed micro stator has low junction resistance due to the good electrical quality compared with the deposited orelectroplated metal coil. Power generation tests were performed and the fabricated stator can produce 5.4 mW in 4000 RPM, 1 and 0.3mm gap. The proposed micro stator can produce larger output power than the previously reported stator spite of low RPM and the largergap between the permanent magnet and the stator. |
