Best DC Motor Type for DIY Wind Turbine Generator for Final Year Project

The discussion focuses on selecting an appropriate DC motor type for a DIY wind turbine generator suitable for a final year project. Recommendations include using a 90V treadmill motor as a DC generator option. However, for improved efficiency, building or using a 3-phase AC permanent magnet alternator (PMA) with subsequent rectification to DC is advised. Resources such as free wind turbine tutorials and plans are suggested for guidance. A Flyback & Pulley (F&P) 3-phase PMA is mentioned as a viable choice, ideally paired with a buck converter operating in discontinuous mode controlled by a microcontroller to implement maximum power point tracking (MPPT). The importance of blade size and turbine diameter relative to desired power output and wind speed (e.g., 20 kph) is highlighted. A specific low-wind permanent magnet alternator model is referenced for direct DC generation.
