“…The alternator-based turbine system is therefore a low-cost solution aimed at making wind power available in more deprived areas, where the current cost of the technology is still prohibitive. Thus, Melcescu et al [10], Lundmark et al [11], and Devornique et al [12] apply numerical analysis by finite element method (3D-FEM) for the design and development of a hybrid claw-pole synchronous generator. The output voltage is easily regulated with minimum power, through the current in the field coil.…”

This paper describes the design of low-cost variablespeed wind turbines by recycling small electrical machines. In this way, electrical machines such as automobile claw-pole alternators, induction motors for domestic applications, or simply electric motors for some industrial applications are studied, considering their reuse as permanent magnet synchronous generators (PMSG) in small wind turbines or hydro-power turbines. The main purpose is the integration of hybrid energy conversion systems (wind and hydraulic turbines) in small stand-alone microgrids within the rural environment. Likewise, in order to optimize the design, the arrangement of the permanent magnets in the rotor is analyzed. The analysis has been carried out using the FluxMotor simulation software, which is based on the 2D finite element method. At the same time, the FEM software provides a lot of information about the optimization of the electrical machine and its multiple design options and topologies. Suggested designs have similar performance as well as a similar size and weight. The purpose has been to explore different topologies and select the most efficient designs. In this way, it is shown that it is possible to reuse an electrical generator easily, without losing much of the general performance.
