Cord to Cordless 18V Brushless Angle Grinder Conversion
Вставка
- Опубліковано 9 тра 2023
- I bought this tool from a japan recycle shop. It does not work properly. There is something went wrong with the armature and field. It starts to heat up after running, then more and more smoke comes out. Suddenly I knew it was gone. To fix it, I need to rewind an armature and field again, but I want to use it with batteries rather than electricity. I spent more than a week to do this project, finally I can do it, and you can see it is in this video.
I hope you find this video useful and enjoy it!
Furthermore, I am happy to receive feedback, suggestions to improve myself.
!!! I'm sorry for the mistake if I did in this video !!!
Thank you very much for choosing to watch my video!
Have a nice day

That's actually quite dangerous to have a difficult to reach push button.
Usually those devices on battery have two buttons, one of them is a trigger that must be pressed for it to keep working.
If not... Good luck catching it when it falls...
This.
the fact that you made a more powerful motor out of two smaller ones is extraordinary.
How is that more power if the controller has fixed output current? It lost power because the windings are now rated for ~2x higher voltage...
@@mihkus no they not, he used thicker wire to compensate for longer turns. and yes, motor size gives you the torque that he needs to do his work. What he lost is the KVA of the engine, 1000KVA is 1000RPM per given volt, now with lower resistance you will need more voltage to achieve the same RPM as before, but then again he gained torque and that's more usefull here that even more RPM, it's good as is.
What T H!!!!
Why you think box of stupidly delicate electronic rubbish better than brush and armature that last lifetime.
Be much easier and better result if you convert to low voltage brushed dc motor.
@@engenhokas69 you probably got education from indian youtube videos
@@matejgamingandotherstuff6484 you just decided to just talk garbage, or it just fell out of your butthole?
@13:23 That bearing was onstalled incorrectly. The friction was on outer wall and you pressed in from the inner wall. Therefore the force has to transfer trough those ballbearings. Ballbearings will damage the groove where they should rotate if pressed sideways like you did.
Creo que el tío si sabe lo que hace
Wow beautiful nice
Estoy de acuerdo contigo y también advertí ese detalle
Привет из России.
За проделанную работу лайк.
Время и ресурсы потраченные на переделку не стоят того, проще купить новую.
Но никто не стал бы смотреть видео, на котором он ходит по магазинам за новой угловой шлифовальной машиной
Я тоже иногда херней маюсь😊

@@vlotaда он просто кайфовал от этого
True !
it's quite a while since i stopping by and this channel has transformed to remaking instead of just restoring things.
Not really sure i like the way the bearings were pressed but the overall project and the fact you wound the motor is impressive.
I also agree with you about the bearing part man, it ain't very good for the them to be pressed that way, the should be pressed from the outer walls.
Yep....always press a bearing in using the outer race.....
But brilliant project none the less.

Probably much better than some of the products out there
Всё сделано классно, за исключением трех моментов. Нельзя запрессовывать подшипник за внутреннюю обойму, статор мотора должен фиксироваться к корпусу надёжно, иначе его будет проворачивать и кнопку с фиксацией на такие инструменты ставить нельзя, это очень опасно.
Согласен с вами. Тоже об этом подумал,кроме статора.
а тот факт, что чувак отпилил провод ножовкой))) ... Да и по стоимости эта болгарка ему по любому вышла на порядок дороже средней по стоимости бесчеточной аккумуляторной болгарки)) Ах. да, двигатель у него в другую сторону на тесте крутился
а вас не смущает тот факт что два новых двигателя,плата,акб,зарядка выходит дороже новой ушм ? 😂😂😂
Чё вы тут все ноете? да всем насрать особенно автору он за просмотр этого ролика на две новых ушм давно заработал.
@@CrazyMan00700зато у него в ушм 2 новых двигателя значит 2раза мощнее должно быть
Crazy amount of work, but the result is really amazing
i love this series from you
the way you connect the brushless motor exactly what i have thought about it
Wow wasn’t expecting you to combine 2 brushless motors! 👍👍👍
its amazing how nice you made this conversion and to know exactly how many turns on the wire to make, you definitely know your stuff. That said it probably would have been easier to buy an angle grinder of this type.
Thank you very much!
This is why I own 5 or 6 grinders , if you let the smoke out , it's done!!!
DONT LET THE SMOKE OUT°°°!!!
You're making such a big deal out of this. Respect to you.
Incredible work, I continue to be amazed by your work with motors.
Fantastic work, but the lack of a safety release kind of surprised me in this build. Agreed about the flat button to prevent accidental on situations, but that also makes it difficult to turn off too.
Could have used a press on/release off kind of button switch.😊
@@armandoperez6673 or a conventional/ stock angle grinder switch
As for the idea, it is wonderful and genius, but there is something that I did not like in this work, is the power button and its place is out of reach, you had to put it in one of the place of the coals that no longer exist after this update.
I will agree to that my friend! He could put that switch somewhere in his finger close by! But its nice modification!
Or even better, a trigger, like the new grinders
Good job with all the best information and knowledge 👍
Parabéns o resultado final ficou espetacular, houve muita engenharia, e ficou sob medida
Hello mister this converted is one of best work beautifully done
First conversion of this type I've seen. Nice. Probably the best quality 18v angle grinder out there. The older tools are just better. No shitty overload/battery/stall protection like most. Hate that on my m12 fuel die grinder, it just stops, I wish it would just bog down, instead it unexpectedly stalls suddenly. Annoying.
Nice work man!
you should probably buy a better die grinder then?
I had a lot of old pipes and rebar to cut up and from what I read ua-cam.com/users/postUgkxPDBfLu68o58Aw85O_J-zIFfjJARBhp-3 this would be the tool for the job. Since I had never used one, I watched a couple of youtube videos and I'm so glad I did. Some really good safety tips, which I followed, and this tool did a splendid job. One good thing to know is the weight of the tool puts just about the right amount of pressure on the metal I was cutting, so I didn't have to use a lot of pressure, which is more likely to jam the tool. It made fast work of my job.
Ogladałem do konca jestem pełen podziwu dla twojej wiedzy😮
This is quite a great job. My respects.
I have been following you for a relatively long time. I am one of your followers from Egypt. I like the type of your videos
nice. I've been waiting for it all the time but only you do this
gracias a tus videos. de restauracion aprendi mucho.de todas las formas q vi de tranformar un amoladora 220 a una electrica de 18 v me quedo con esta version de video.las demas vi no llegaban a la fuerza q muestras esta.y eso q tambien tenian torno y todo las herramientas para hacer dicho proyecto.gracias a tu canal las cosas q encuentro las puedo restaurar mejor sume mucha experiencia,uno de lo mejorsitos canales q vi de este nicho
Great work ,,, could you publish the motors specifications or link ? also the controler 👍
Now that's some next level stuff
Amazing process
Where did you get the bear puller from? It looks like a very useful size.
I love what you did here - Well done - Bravo !
I'm glad you love it, thank you!
@@gear_show You are welcome - Much respect to you. 👍
@@gear_show link of that motor plzzzz
Great work 👏👏
When you press in bearings, you press on the outer race, not the inner race. this avoids damage to either race and/or the ball bearings in between. Other wise it was a nice job (ignoring the little boo boo of cut leads.)!
That is excellent tips, I do appreciate that.
Yeah, I saw that but I didn't see him fix them
Un trabajo titánico , me parece increíble lo que haces , enhorabuena por el canal.
Muchas gracias por compartir , un saludo.
De nada, ¡muchas gracias!
Nice work!
13:20 The outside must be pressed, not the inside. Pressing the inside during installation, it can cause a damaged bearing 🙏
Nice work
Wow you are the best DIYers👍👍👍☺️
I enjoy watching and following your videos. Where do you supply/buy the empty battery boxes and equipment you use?
what prevents the motor from rotating itself? I see you use a setscrew between sleeve and stator, but what makes it hold on to housing?
Well done, as always surprised us with his work 😊
Master at his craft
I love your brushless motor conservation series🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃
did you fall asleep on the keyboard?
Мне понравилось когда перегородку корпуса пилил ножовкой,заодно и провод перепилил от статора))))
Too many negative comments without work? You should be ashamed.
Keep up the good work, I'm waiting for your next amazing work.
Great work.
Excellent video 💕💕
Que trabajó más ingenioso, muy buena idea.
Felicitaciones
I am not sure if the speed controler will last too long, especially if you force it. since it has to take the load of basicly two motors now. And usually these Controlers are used with switches wich gradually give power. All those on/offs at full power will burn it quick. It would be nice if you could use an RC testing switch wich can gradually increase power and set what speed you want.
Also I am kind of a welder sometimes and i've been used the angle grinder to cut alot of metal.
I've found the thin discs, the 1 mm ones to be best for cutting metal, they cut faster, cleaner, heating the material less and giving you a more precise cut. At first i thought those are only good for cutting thin metal sheets, but is good for anything you wanna cut. The only thing you have to be careful with when using them is when you cut tubes and thick pices of metal not to pinch the disc as you are grinding through the cut, those thin discs explode very fast. But even if they do if you have good eye protection and a cover for the disc you are safe.
I think alot of people are afraid of those discs as they are so thin but once you learn to work with them, trust me, you will rarely use these 1.5, 2mm ones to cut anything.
Good work. An idea for second video: buy a pwm controller and pwm driven motor driver as for rc quadrocopter, with soft start, soft and immediately stop. And good idea for safety is to add a body button to stop instrument if you loose your hand over it.
Okay, thank you for sharing! That is a great idea.
Congratulations Gear Show on this successfully completed restoration...❤️❤️❤️❤️🤟🤟🤟😘😘😘
Nice adapting
Un trabajo titánico , me parece increíble
where did u buy the motors
Nice info ,thanks for sharing it :)
Yes very good! Only you must change the Type of switch for SAFETY precaution
nice job overall the only problem with this it's that after purchase all the necessary parts it's end up costing more than a very new cordless grinder all together plus all the work to putting everything together . But on the other hand it it's a very good to have something custum that no body else has and I really like that .
That is true, thank you!
It is also a great demonstration of how motors are winded and work.
Thx for the video, inspiring!. Impressive work, but if you count time work time for planning, procurement, parts and tools usdage you'd better buy a new one.
Awesome, I’m gonna have to try this
Reducer bearing was installed incorrectly, You should push on the outer shell not inner. Overall not bad.
I xzz ş
Very good work 👍
That's powerful man😮
Gratidão GearShow! Ficou top!
Very good!
Thanks!
Just love your Videos.
Great Job
Beau travail !!! Merci de partager !!
Good job, keep it up.
Ignore all negative comments because you completed an amazing transformation from a clapped out, burned out piece of junk to a fresh cleanly built cordless, brushless, powerful angle grinder which almost all of the people who wrote negative comments wouldn’t be able to do themselves. It’s not always about time and cost affective value, it is a project with 100% results so ignore the haters and I am not slating the ones who have pointed out of some alternative ways which may or may not help you in future projects I don’t know, all I am saying is you have done a great job and I for one took a lot of positives from it, well done
Yeah, the experience of how to do it is not necessary.
fantastic work. and a big but. the parts cost as much or more than just buying one new. and most of us dont have lathes ,presses. other tools. and your electrical knowledge
This is an enviable accomplishment! Bravo.
Thank you! I'm glad you like it.
What kind exactly, of engine I mean model of bldc motor you replace on ?
Muy buen video ! Solo un detalle : por seguridad ubiese instalado un gatillo pulsador en vez de un interruptor por seguridad
UN PROFECIONAL FELICITACIONES PORQUE TODO EL PROCESO DE PRINCIPIO A FIN EXELENTE
the best homemade work！
how much drill bit do you use to drill the shaft hole 4.9mm or 5mm
I genuinly love the fact when making that L bracket thing fit that they used annother angle grinder to do the work. It's fun because while you know the same result could be achieved another way it shows you that said tool type is useful, nicer, or just an easier way to do the same thing.
I'm glad you like my work, thank you!
you're just amazing. respect.
Simply the BEST!!!!
You're a lunatic. I like your style!
This is mega step up on your restoration/upgrade game! 😍😍😍😍😍
ki mo on
I noticed that the spacer sleeve you made to go over the stator was cast iron not steel. Necessary for the magnetic field.
Шедеврально, респект 🔥 золотые руки!
колхозная залупа по цене норм болгарки... однозначно шедевр=)
Excellent work 👍👍👍Thank you for sharing. Be safe🇨🇦
Master👍
Really good!
Glad you think so!
Excellent
Bravo 👏
You are really master
Perfect 👍
Thank you! 😃
Always Enjoy Watching Your Work
Muito bom👏👏👏👏👏👏
thank you teacher❤❤❤
Great job, thank you brother. You are so talented
is the stator plastic?
excellent indeed !! just one suggestion, do not mount the bearings putting pressure on to the inner race or ring when assemble that into a housing.
Thank you so much for sharing
Great job.
You got a lathe?!?!?!?
Oh my goodness.... The sky is the limit now!!!!!
Everybody has a lathe, 🤣🤣🤣 except you and me 😭😭and please don't say you have a lathe too 😵💫😵💫🤣🤣🤣🤣.Peace
😅😅😅, I don't have it too
@@yeagerxp I do NOT have a lathe....
建議電池座的方向換一下比較順手，目前電池方向和砂輪片同方向，使用起來某些角度會卡到電池，切割時的火花也可能噴到電池、可以參考makita 電動砂輪機的設計比較順手，個人小小建議
Di dukung dengan pekerjaan yang sangat baik dan rapi hasil nya pun memuaskan... Selamat buat anda....
Wow! such drama and suspense! I can hardly wait to see the conclusion.
brilliant and genius
you are ingenious
0:40 Magic smoke is always welcome 😂😂😂😂😂😂
Every machine is a smoke machine if operated wrong enough. - Someone smarter than me
Does someone knows what's the type of 18650 cells he's using? NCR or HG2?
Congratulations for sharing and brilliance. I ask you where did you get two scooters brushless? or at least a link to buy them. Thank you
Really cool.
Great Job!
Thank you!
