HELLO. This trial is great. Everybody is bothered from rectifier and voltage regulator, it sound like protection from malfunction but it works not to get big energy from alternator. Your trial is a breakthrough. If you turn the pulley faster by machine, this alternator can have much more voltage and current. I was encouraged.Thank you!

The rotor should have contained a larger magnet for higher flux density. The rotor is too heavy and more metal should have been removed from the same. Also you should have lubricated the same so that it rotates faster.

@cliffcampbell8827 3 жыл бұрын

A quick way to drill holes with a consistent set depth, 1: find the desired depth 2: drill first hole to depth then stop drilling 3: with the drill bit stopped and in the hole, wrap some masking tape around the drill bit's circumference at the surface of the material being drilled 4: back the bit out of the hole and start drilling the other holes. The masking tape is easily removable, won't damage the bit and clean up is a breeze. Heat and tapping compounds might cause the tape to melt or slide off so you might want to think about using different types of tape or permanent markers/paint to mark the depth on the bit.

@mgabrielle2343 Жыл бұрын

There is a limit as to how much thicker a wire can be as the current is not determined by the thickness of the wire but by the strength of the magnets, so if your magnets can only produce 1 amp then it does not matter if you have 1mm dimeter wire or 2mm thick wire it will only produce 1 amp or may be just a tiny fraction more due to the resistance to 1 amp current flowing through the wires, Power Generation is the product of the strength of magnetic field and speed of rotation, voltage is proportional to number of turns and strength of the magnets and the speed of the rotor. And nothing comes out of nothing, so if you wanted more power then you also need more input power to spin, (Torque)

@peterbetts8740 Жыл бұрын

Car alternators need to spin at very high revs to make even just 12 Volts. While on the car they will be 'geared up' and be running at 2 or 3 times the speed of the engine. We are talking 10 to 20 thousand rpm - just to get 12 Volts A much better conversion would have been to leave the brushes and the rotor coil intact and power it from a single diode connected from the output of the stator coil. This would be after removing the original stator coils, noting how it was wound, then re-winding it with some much thinner wire. This will give more volts and at lower rpm - making the resulting generator much more useful. Rewind it as was, as a star connected 3-phase and connect your diode from one of the phases and back to the centre point of the star. Or make a 3-phase bridge if you prefer. It will self-excite and the existing rotor coil will make a much stronger magnet than the permanent magnets ever could - giving you greater output. Get as much wire into the stator as possible, every extra turn is worth more volts Do not be greedy and expect mega mega output. For a machine/device like that, self-excited as it will be, do not *ever* hope for more than 200 Watts - but at least it will give measurable volts and useful power if built into a wind turbine.

En principios tecnicos, funcionaría, pero debido al reducido tamaño de los imanes permanentes, dudo mucho que tenga un minimo de torque necesario para impulsar cualquier cosa, el puro rotor genera un torque inercial muy grande en comparacion con el tamaño de los imanes de neodimio que coloco el hombre en esta publicación, en todo caso podrias colocar imanes mucho mas poderosos para asi poder generar mas torque, pero eso incrementaria mucho el costo de este motor, ya que mientras mas grande sea el iman de neodimio, es mas caro y necesitarás muchos, haz numeros eh investiga precios y te daras cuenta de que será inviable si es que quieres mantener los costos bajos, yo te sugiero que utilices los anillos rasantes/rosantes como estan, no es caro reemplazarlos y las escobillas son muy baratas, saludos. Edit: Necesitarias un controlador adecuado para la versión de anillos rasantes/rosantes, aqui no funcionaria el BLDC ;)

The reason you hammered it(which did the rotor no favors at all) was that you had the rear bearing come out with the rotor which it should not do. You should have removed the bearing, cleaned the rotor, install the bearing into the back case, then install the rotor(after lubing the shaft in the bearing area.

Output on this type depends on how fast the rotor is spinning and how powerful the magnets are. No input power is needed because it's brushless. Less power is generated for sure but also less is needed to generate something.

Very interesting and well explained but the small magnets set into the big surrounding area of steel, will not work. The upward facing pole of the magnet will be cancelled out by the surrounding steel acting like the opposite pole. So you will not have clear and distinct North and South poles!
