Updating the mini lathe to rewind the armature of electric motors.
Hi there! In this video, I'm going to show you a device that I created for my desktop lathe. The goal was to make it easier and faster to rewind the electric motor armature. I added an inductive sensor and pulse counter to the lathe, which allows the motor to be turned off after a certain number of rotations. Some of the parts were printed using a 3D printer, making the process much easier for me.

please explane to me , How would I know the number of turn[the cupper coil] from one slot to another slot? by mines how many turn?
Cut or unwind the wire and calculate
nice
Thank you
how did you know there were 34 windings - did you count them but how they were hack sawed off?
I counted it. The video shows how he sawed it off.
Hello. I have a Bosch GST 90 BE which is almost new and not working anymore at all. After opening it, I see that I have my 240w on the carbon brushes if I remove the rotor. Once I put the rotor, it looks like I have nothing reaching the brushes. Is it more likely to be electronic issue, or rotor issue? How can I be sure before ordering the right part? Thanks a lot
Hi. I'm checking the rotor with an inductance tester. You can also use a resistance meter, but it may not help in all cases.
@@valsworkshop thanks for the quick answer, but what should be a "good value", and between which parts should I test it?
@@valsworkshop also, to know for sure, is it safe to say that I can just bring electrical power directly to the stator (240V directly from the plug) and see if it turns? If it turns, it means the problem was most likely the speed controller, and instead, that it is the rotor?
@@gandhorn It is not the exact value that is important, but the difference between the coil readings. If the difference is 10-15%, then this is good, and if it is more than 50%, then there is most likely a malfunction.
@@gandhorn If it turns and there is no excessive sparking of the brushes, then the stator and armature are in good working order
Very close to being an educational video. Is the number of turns of the copper wire is random or necessary for each type of motor? How can I have this information?
To find out the number of turns, you need to take the wire out of the groove and count it, and then divide it by the number of sections in the groove.
what liquid/putty did you use for the windings? I need that
The windings were impregnated with epoxy resin
What do you do when you are bending armature tabs and they brake?
I didn't understand you. What did you mean by that?
Это китайский станок? Как качество?
Нормальное
Actually first video of ac armature winding I have got idea how to do it. Great bro
Thank you
I want to rewind two armatures give me wapp no.
Hi. I don't have any wapp.no
It was very satisfying to watch. While lotta work!
Thank you
Clean the carbon with Aceton. And the carbons too.
Thank you
Для первого раза покатит. Как балансировать будешь - не знаю! Последние катушки будут сильно выпирать. Если дома мотаешь, нет станка для балансировки, надо с двух сторон мотать в два провода. Пару катушек в один паз, симметрично пару со второй стороны, опять пару (по числу ламелей)первый ровод, пару вторым. Тогда последние катушки лягут симмитрично в конце намотки. Дисбаланс будет минимальный. Удачи.
Спасибо
Проверь конденсатор,если он не рабочий,то будет искренние
Спасибо. Не знал об этом.
With such an abundance of tools, isn't it easier to buy another tool?
Of course it's easier.
Not when the motor you are working on has not been produced in 90+ years. Easy also does not always equal right.
سلام واقعا کارت عالی وفوالعاده بود ممنون بازم تعمیر کالاکتور برنامه بگذارokkk👍❤💚💛🇮🇷

С удовольствием посмотрю ваше видео о правильной пайке
awesome

Errou em colocar o mesmo coletor ele ja estava com fuga
É possível
Hello, did you do the winding in series because that's how it was, or did you do it that way because it's easier than in parallel?. Thanks.
Hi. I wound it up like that because it was wound up like that before.
ИЭ1035 из 80х схема перекрещеная.
Вы правы
You should solder the wires to the commutator. Good point made in the comments about filling the gaps between the commutator segments.
The paths between the slats do not need to be filled with anything. There are new collectors whose tracks are filled and they need to be milled before installation.
Du beau travail !
Merci!
После несвоевременной замены счеток начал сльно искрить колектор. Одтал токарю на проточку. Был овал. После проточки осталась 1/3 толщины ламели. Думал конец. Но решил продолжить. С трудом отчистил прорези. Собрал перфоратор. Сетки искрили также как у вас. Синим пламенем. Решил прижать установленные счетки при включенном двигателе. Искрение уменьшилось. После нескольких повторений разобрал и почистил мелким наждаком колектор. Собрал перфоратор и проверил. Искрение существенно уменьшилось. Колектор греется, но прочитал, что его температура при работе может достигать 200градусов. Развел проводку в 1комнатной панельке, просверлил в силикатном кирпиче 2отверсия диаметром 25мм. Перф бочковой 1200Вт сдс+. Может еще походит😊
У меня искрило по другой причине
Не проще купить новый? Нет я понимаю экономия должна быть экономной но если работаешь и этим зарабатываешь то лучше не скупиться а то может в лучшем случае подвести не вовремя а в худшем и последствия могут быть, я даже для дома если покупаю то сломался и черт с ним проще купить новый и забыть на пару лет

I want to learn how you balanced the rotor. Can you explain that.
This is a static balancing "on knives"
@@valsworkshophow can we do it with steps
Static balancing on knives is the simplest method of determining rotor imbalance, which uses knives or prisms mounted strictly horizontally and in parallel. If you allow the wheel to roll freely over the knives, then after stopping, the center of mass of the wheel will take a position that does not coincide with the bottom point, due to rolling friction. When the wheel rotates in the opposite direction, it will take a different position after stopping. The average position of the lower point corresponds to the true position of the center of mass. Static balancing allows you to reduce vibration, load on bearings and increase the durability of the machine.
@@valsworkshop thank you for your kindly reply.

Hello, Professor. First of all, congratulations on the video, and please, I wanted to ask you a question: I have an armature from a vacuum cleaner, in which I cannot see the beginning of the coil. It is made in China, it has 24 wires and 24 slots, and since it is so automated, the starting point, wire/wire, is almost invisible, at least for me. In these cases, which almost certainly has happened to you as well, what do you do? Do I clean everything and start wherever I see fit, do I have to look for a coincidence between the slot and the wire, or what do you recommend? Thank you very much.
Hello. Before cleaning, it is necessary to remove the winding circuit. I apply a low voltage to the lamella through a transformer and use a thin steel plate to determine the grooves.
Здравствуйте, у меня точно такой перфоратор как у вас , но якорь немного другой, намотка идет в другую сторону с лева на право. Я при снятие обмоточных данных, повредил провода, так как все было залито эпоксидкой возле коллектора. Хотел у вас уточнить схему намотки якоря, чтобы применить к себе. Основная ламель находится напротив первого паза, назад через одну ламель?
Здравствуйте. Нет, на моем напротив первого паза находится вторая ламель, первая справа от нее. Намотка параллельная, с разделенной катушкой, т.е. у первой катушки сначала мотается вторая секция (намотка начинается со второй ламели). Провод 0,355, 20 витков в секции.
Балансировку надо делать после проточки и полировки.
Спасибо
Very impressive how you did that with such simple tools and techniques!
Thank you
Yep! CNC mills are very simple and cheap. 🙄
Just Wow!!! 😮
Thanks
Fool's errand. If you can find a new commutator, you can find a new armature. Armatures are wound "wet" with epoxy potting applied to the wire while winding. Just painting it on the ends doesn't do the entire job of securing the windings against thermal expansion, wear, and eventual failure.
Is epoxy resin applied during wire winding? I haven't heard about this yet. Do you have confirmation?
@@valsworkshop у таких ширпотребовских устройств пропитка производителем не делается, а в более приличных - пропитку делают в ваккуумной камере, откачав воздух с последующей заливкой разогретой эпоксидки
@@ivan_filimonoff Еще не попадались якоря без пропитки у двигателей работающих от переменного тока, даже у самых дешманских есть пропитка. Вакуумная камера это конечно хорошо, но имеет смысл только на производстве - при ремонте одного якоря слишком большой расход эпоксидки получится.
Даже в самом дешманском инструменте якоря с пропиткой
Міжвиткове замикання може бути також і в обмотках статора. Статора ми перевіряли, якщо не помиляюсь приладом ЄЛ -... Це також може бути причиною іскріння.
Не в цьому випадку
Після перегляду Вашого відео, у мене знову з'явилось бажання перемотувати якорі.
Добрий день. Якор потрібно перевіряти на міжвиткове замикання. Є різноманітні пристрої. Самий простий варіант : спеціальний саморобний трансформатор.
Привіт. Перевіряв за допомогою тестера індуктивності.
@valsworkshop багато є ще інших причин. Пробивання на корпус перевіряли, мегаомметром?

Back in the ‘60s I used to rewind the three pole armatures to hop up slot car motors. That was pretty simple. This, tho’ is another whole level of work. Pretty amazing.
Thank you
great work, many thanks for the detailed video of repair for the rotor of a started ... actually personally this is not my job, I need to repair one like this similar rotor but I will take it to a workshop in my area is not worth it to invest materials and equipment for one rotor ,, in any way this was a very interesting video of the technique you present here on youtube for the right procedure, many thanks from Europe Greece, kind regards ... !! (correction the rotor in this video is ac, not a starter dc )
Thank you!
Brave man!!!❤️👍
я с опытом перемотки якорей говорю тибя. начале сразу видно што колектор уже замкнут и конце видео когда запускаеш мотор и сразу чути што в колекторах прблем!
Спасибо
А зачем?
OK!
Great effort but in today's market why bother ?
Ошибка номер один, ...балансировать нужно ПОСЛЕ проточки якоря. Якорь нужно было проверить на пробой ДО намотки провода....
