The purpose of this project is to research the performance of locally manufactured Axial Flux Permanent Magnet (AFPM) generators, which follow the design explained in Hugh Piggott’s building-manual “A Wind Turbine Recipe Book”. The main focus of this report is on the applicability of AFPM generators for:
- Small scale wind- and hydro applications, aiming at electricity production
- Renewable electrification projects
- Educational purposes within European-wide engineering departments and training centres
The three different generators subject to this project follow a very simple manufacturing design. It is possible to build them without specialized tools or expertise as well as using basic materials. In fact, the design has been successfully reproduced all over the world, thanks to the mentioned building manual developed by Hugh Piggott. Despite their reproducibility, they are competitive machines, in terms of efficient performance, long term functionality and manufacturing costs. These aspects make them very interesting for a variety of applications, one of them being small scale wind- and hydro-powered systems. Moreover, the fact this AFPM generator-design can be built in common workshops and by non-professionals, make them a very powerful educational tool. By constructing, testing and analysing such generators, many important concepts of engineering can be applied, making the learning process particularly interesting for educational institutions with a technical focus.
