Eddy current dynamometer for wind turbine testing

thingiverse

This dynamometer is based on the phenomenon of magnetic induction and is specially designed for measuring the characteristics of wind turbines. In fact, this is the equivalent of an electric generator with short-circuited windings. The resistance force is adjusted by changing the magnitude of the magnetic field. https://www.youtube.com/watch?v=RNPaZzP1N6Q https://www.youtube.com/watch?v=Bodt6ze6Wck In addition to the printed parts, you will also need: Neodymium magnets 12×5×3 mm. 14 pcs.
