Cord to Cordless 18V Brushless Angle Grinder Conversion

[@science7542]

the fact that you made a more powerful motor out of two smaller ones is extraordinary.

[@mihkus]

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...

[@engenhokas69]

@@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.

Not really sure i like the way the bearings were pressed but the overall project and the fact you wound the motor is impressive.

[@BDFireFist]

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.

[@AdamDitheridge]

Yep....always press a bearing in using the outer race..... But brilliant project none the less.

True !

[@madvelila]

@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.

[@yakine13]

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...

[@racing_mntage1584]

This.

[@SororYoussef]

what did you build ??

[@stuartodell1709]

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.)!

[@gear_show]

That is excellent tips, I do appreciate that.

[@maryboyle5515]

Yeah, I saw that but I didn't see him fix them

[@maxheadroom1506]

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.

[@gear_show]

Thank you very much!

[@scottyhankemeier9380]

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!

[@BloodSprite-tan]

you should probably buy a better die grinder then?

[@andreykuznecov9635]

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.

[@BlackCoupe-s5s]

Согласен с вами. Тоже об этом подумал,кроме статора.

[@СергейВоробьев-щ6у]

[@suecordon8763]

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

[@Nitrofan_Kerm]

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.

[@gear_show]

Okay, thank you for sharing! That is a great idea.

[@wilberumana6521]

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 .

[@gear_show]

That is true, thank you!

[@matpold]

[@Dipplers]

[@ohne_Gnade]

yeah, and then using another motor at the end... (look at the copper wire winding before/after and the heat shrink at the motor wires) ;)

[@lukeolinger6000]

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.

[@armandoperez6673]

Could have used a press on/release off kind of button switch.😊

[@AlphaTroniks]

​@@armandoperez6673 or a conventional/ stock angle grinder switch

[@hicham1101]

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 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 had a lot of old pipes and rebar to cut up and from what I read kzbin.infoUgkxPDBfLu68o58Aw85O_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.

I think you shorted out the laminated stator core with that sleeve you pressed in. You should have insulated it. Now it will generate a lot of eddy currents and slow down the motor, reduce the efficiency and generate heat.

As you are using a brushless controller, maybe it would be easy to add a potentiometer and have proportional control of the RPM. Could be useful to throttle it is some situations, and not all angle grinders have that feature.

I noticed that the spacer sleeve you made to go over the stator was cast iron not steel. Necessary for the magnetic field.

[@ВладимирВинокуров-ь2в]

the set of stator core sheets should not be shorted, and you put it in a steel sleeve. This is the first. Secondly, bearings cannot be pressed into the inner race! Third, the wire needs to be wound carefully without twists or creases and as evenly as possible, this is not the case with you. Fourth, the general impression is that you have never held a soldering iron in your hands, not to mention rewinding motors... And everything turned out easy and simple for you))) I don’t believe you)
