mini generator, alternative current 230 V, using a coil without core, a neodymium magnet sphere 19 mm - 30 mm , a dc motor and a battery, which can light up a bulb 3W - 75 W 230 V<br><a target="_blank" rel="noopener noreferrer" href="https://www.youtube.com/watch?v=KErVBeGeUOE">https://www.youtube.com/watch?v=KErVBeGeUOE</a><br><a target="_blank" rel="noopener noreferrer" href="https://www.youtube.com/watch?v=Ud3fMcn7GAw">https://www.youtube.com/watch?v=Ud3fMcn7GAw</a>
The secret of the presented small generator is that, the coil (stator) provides a "total capture" of the magnetic flux generated by the spining neodymium sphere ( the stator) - this is possible using a sphere shape which is fixed on the pot metal case between the magnetic poles . I manage to avoid the " standard brake" positioning the sphere a little higher than the stator ( coil ) but I need to increase the RPMS ( I am using 2 poles spheres). I consider it a succesful educational layout, created in educational purpose, not in commercial purpose. Probably as an industrial generator needs a lot of improvements
small generators, my hobby....
