Axial Flux Permanent Magnet Synchronous Generators for Pico Hydropower Application: A Parametrical Study

A pico hydropower plant is an energy harvesting system that allows production using the power of water flowing in small watercourses, and distribution network. Axial Flow Flux Permanent Magnet Synchronous Generator (AFPMSG) are particularly suitable for this application, being efficient machines achieve high with dimensions. This paper presents a parametrical study several configurations topologies three-phase single-phase AFPMSG, to assess most dimensional characteristics safe voltage 25 V. The AFPMSGs here considered has simple single stator rotor configuration, commercial-type permanent magnets, concentric windings, facilitate their cost-effective construction spread use also developing countries. For each AFPMSG considered, output was calculated 3-D modelling Finite Element Analysis; besides, different parameters features affect were evaluated at rotational speeds. results achieving density up 100 W/cm3, 1000 rpm produced 1.7 kWh/day.
