No awareness…? Really?!? I think you’d have to be pretty aware of what you were doing to calmly and quickly do the work they do, in their osha approved sandals..while all of them work in close proximity to each other…you’re correct about the safety, safety sandals and all but I would strongly disagree with you when it comes to their “lack of awareness”
Motor repair shops are one of old school businesses that are staying open because of commercial side where you can’t wait a month on a motor to be shipped from China or in the HVAC industry where it can simple repairs like new bearings and know that $500 motor is good as new.
@@MatthewMattoxcube8021 Absolutely! It just sucks that most residential grade motors these days are made using oilite bushings instead of proper bearings. Problem is that those bushings usually don't have reservoirs any more, which means that the motor only lasts a year or two before seizing.
There used to be a motor rewind shop just down the road from me. He was the only guy who done stator coil rewinds for motorcycles in my whole country, I used to get him to rewind mine all the time, and he done a wicked job. He would get plenty of business but sadly he got old, and his kids weren't interested in continuing the family business. They closed down and now the only option is to buy a complete overpriced pre-built stator which is most likely made in china. Sad times
North winding, south winding, flip 180 do again. Next pair, flip 180 do again. Then final pair or as many as needed. Wonder what its for. That coil is mega thick. What are its characteristics you think? Low voltage high current? Man coils are weird. It’s practically a short! Im going to order some cores and a set of different gauge wire so i can have a better grasp on configurations.
It will always perform better by hand coil but yes that method is how proper brushless motor winding goes but despite that what do you think this goes to? 12 or fourteen gauge wire must be for something larger
This was both educational and a good ASMR video. I know understand how the windings are in pairs and how the direction of the winding affects the poles of the electromagnets and that the extra winds around the shaft are for the flying leads when wiring up the armatures.
витков насчитал 11-12 на разных катушках, но неравномерность наматывания из за того что мешали провода на валу, и последние витки были выше положенного, начиная с 4 катушки.
@@MVA6195L é Left, esquerda. R é Right, direita. Em um induzido como esse, estamos vendo a orientação de campo que deve sempre estar fazendo um sinal oposto ao outro lado. Logo, temos um R e do outro lado da conta um L para termos inversão de fase e fazer o motor funcionar. Forte abraço
I built a little atlas antigravity machine when I was younger… I looped my own wire. Hated every second of it. Then my dad told me the iron plates I had were too thick… I already finished. So I had to do it again with thinner plates, hated it even more. But the machine worked, got my little metal earth to suspend in the air. Used a solar sensor to adjust the voltage to the magnet so as it spun if it started to drop from the magnet, the solar sensor will pick up more light which tripped my breaker and pushed more power to pick the little metal earth back into position. I hate wires! But learned a valuable lesson in electro magnets. That lesson was, get your math right before you build. Or an old man with 20+ years of experience in electricity will tell you, you fucked up just by looking at it.
A small rotor like this whit rather thick wires as shown in video wouldn't maybe take hours to make one but it would still be hard to make the coils consistent and whit small wires deffinetly hours even on small ones
Years ago l raced slot cars,and re wound many small motors by hand ,carefully counting the turns according to wire size specs.We filled the voids with araldite and balanced the whole armature on razor blades. Finally drilling the iron in the heaviest places and final balancing with a drop of paint......when complete they would spin like a top on a glass plate and screem like a siren....those were the days.
Looks like the creation of a stepper motor, the way they connect one side and then the other and then do another set on different loops. One coil on each side activates HIGH and LOW to pull the motor in that direction and then the next set of coils activates.
tbh a stepper motor is a brushless motor with extra steps (though they usually inrunners, as in the rotor is on the inside, and the stator is on the outside.)
i see it as a stepper motor is a brushless with steps and a brushless has no steps, since the stepper has actual teeth to make steps, but the brushless doesn't so it doesn't step. @@satibel
Wow, so it is those extra smooth curved surfaces that do the hard job of fitting the coils into the narrow slots! Makes it so easy! Simplicity of it is amazing
There's more overlap in some more than others. Would that cause any inefficiencies? Also, what happens to the extra copper on the white part? If removed, how do the rings stay connected?
Slight inefficientcy but negligible, but whats matters most is equal amount of turns on each pole. Not sure about the tails it made but they could be used to connect the windings in different configurations
@@henryraab3111 Tesla as great as he was, had no hand in the creation of this machine, only the principles used to decide what this machine needed to do.
@@henryraab3111 I'll state this another way for you. The impressiveness of this machine is not in it's application of principles developed by Tesla. Tesla's principles have nothing to do, directly, with being able to design a 'simple' machine that is able to perform the task of wiring a motor in the fashion shown.
The tool for winding a bobbin is really sophisticated, sir. As a mechanic, I used to think, this is how to roll it, how come it's so neat... It turns out this is how and what the tool looks like...
Technically it's a magic to me, but then what to do with those rounds of wires over the white plastic axal which connect all the 12 slots so can't be removed by cutting?
Reminds me of years ago when l used to race slot cars.When the Motors burnt out we used to rewind them in various combinations of wire thickness and number of turns.Following the process we would fill the voids with araldite then balance on razor blades,and by drilling the armature and providing a spot of paint in the dimple if needed….they used to scream like a siren….till the next rewind….great fun though.
meanwhile i sit in my backyard taking things like this apart to inspect how they were put together in the first place so i can make them myself while forgetting i can just look it up
Я не богат и нет заводов и связей но есть знания и ум. Делайте и увидите результат вечной инергии , вы не будете тратить жизнь на заправках авто на заготовке дров и на извлечении газа нефти. А так как нефть и нас добывают не все заполняют пустоты земли это земля провалица в пустоты а испарения убьют атмосферу и давление космоса нас уничтожит мы потребляем много очень. Я не зелёный ни ученый я простой электрик монтажник элмеханик. Всем добра и удачи.
I'm kind of glad robots can do this imagine doing doing all this by hand. I've made small little motors for science class it barely moved but Jesus a big one would be hell
Маленькими азиатскими ручками А если серьёзно то это по сути просто трёх фазный моторчик и при правильном соединении всё будет работать и сможет разгоняться до 2000-3000 оборотов
