I recently converted an old 2 stroke trimmer to 36V battery powered. Was heavily inspired by this video. I direct drive the shaft with A 24V HVAC blower motor. Overvolting to 36V with 2 18V batteries gets the the RPM on par with 2 stroke and roughly the same total power output.
The way you design circuit boards is just crazy. It's insane how well you put together different disciplines of engineering. Also, you cut metal with an angle grinder like a pro.
pro tip: when you are cutting metal with hole saws (especially large ones) to avoid the hole saw from jamming up into the steel and splitting your hand into two, clamp the steel with some c clamps, (you will also save motor power doing this)
Try aircraft :" grave yards" or surplus/ obsolete military : some 24 vdc 48 vdc ( just a tickled: if not doing it in the rain?) OR wait for Buydumbs electric America = SOLOR CELL CLOTHES & PROPELLER'S ON OUR UVC HATS TO KILL COVID & NOT US? OR >>> NAIL CLIPPERS & PAY PER VIEW?

Interesting. Everything done properly. I have some doubts about the long-term capacity of power tools. The relatively large torque compensates for the relatively low power. The donor seems to have a ~ 1500W motor in the glory days. Does the current motor have 150W? How long does the battery last?
I'm not sure if that motor is really meant for constant duty... Like, running it at it's rated voltage for 10-15 minutes at a time. Then again I guess it would get a cooldown in between battery charge cycles.
I like this a lot. Looked powerful the weeds you was cutting was pretty substantial. The tough stems is hard to cut and it looked to do it without a problem.
Certainly helps when you have a shop with every machine imaginable. Circuit board making and 3d printing and so forth. But is really that much cheaper than just buying am battery operated one?
This video is awesome. Well done. Please answer the following questions: What is the run time like with the battery you made? What is the Ah rating of the battery you made? How does the performance compare to a gas version?
@@jclowe735 Oh shitty.. cowdung.. 775 motors comes in 12v and 24v, if you want maximum power out of it, you'll need more amps and make sure you have spare batteries coz it draws lots of amps while in action.
@@chongshenchang9367I got my hands on a similar motor and it pulls 2 amps at no load (12vdc) and I pressed the Shaft down on a tiled floor to resemble a high load condition trying to stop the rotation which it didn't but started pulling 8 ish amps. Hope that helps.
Interesting, but I think a new brush cutter would cost much less than for the new motor, buying and making parts, time used, compared to the result. How long runtime do the battery give you? How many hours did you put into it? How many parts were all new?

Yes that's correct. But the leverage to balance the rod while maneuvering left and right swing will be a problem. Motor at the lower end will make it very heavy to move. But your point is valid. Can be mounted on couple of wheels to roll on the ground thereby relieving us of the load.

The angle on the handle is all wrong :-D You are leaning forward when using it, and that stresses your back. It's designed to be at a 90 degree angle to the main rod.

I like the way you locked the drive gear to the hub with a machine screw. It's like a keyway and a locking bolt all in one! Awesome!

I don't think the goal is to make something cheap, it is rather to do something with a tool that would otherwise be garbage.
You're right
Dobra Robota PANIE 😉😂😂
After see this, now much understand basics of electrical tools.
Super Cool....👍🏻👍🏻👍🏻
Great fuckin' video. Strait to work and no boring shit. THANK YOU!
Your skill is superb.nice sir
Thanks for the plans!! I'm building this asap
Looks like it would b ok on small grass but taller stuff I think it would struggle with.
Fantastic work, Maciej! 😃
It's infinitely better now!
Stay safe there with your family! 🖖😊
That's awesome Maciej. Keep it up.
great idea

Please answer the following questions:
What is the run time like with the battery you made?
What is the Ah rating of the battery you made?
How does the performance compare to a gas version?
I think it won't last an hour because that motor draws a lot of amps.
@@chongshenchang9367 makes you think what would a 775 DC motor do if it was used as a replacement for the gas engine.

Brawo Ty :)
Few dangerous cuts and lack of fastening in the drill press. But love that work in general.
Step 1: have an expensive gasoline brush cutter laying around xD

Which motor you used
He said it was a car power steering motor.
I would had push button switch safety you dropped cut power. But cool tool
Very nice. Give me one piece. I will pay.

is it rechargeable.?
You're certainly great, but I don't have a turning and 3D printer...
And....

A jakiś silnik ze szlifierki katowej ?
If you keep the motor unit near to the blade, you can avoid the rod (shaft) and its weight, so you can save much energy.
Good luck

@@gizmobrain Makita makes both but the ones with the motor near the blade handle a bigger blade so I guess they have more torque.
The angle on the handle is all wrong :-D You are leaning forward when using it, and that stresses your back. It's designed to be at a 90 degree angle to the main rod.

How long did it run for?

Do they make these? It appears to work exceptionally well!

cheaper, quieter, healthier, more durable and waaay more ecologic : a scythe.
try to use that scythe, like he idid near stones and small grass between stones. scythe is ment for large hay. use things as they are designed
Please give a 5 year update!!!
Can someone explain to me how this "soft starter" is built? Is the start of the electric motor limited by a resistor or a capacitor?
Not sure why unless the motor is blown cause the battery wouldn’t be as powerful or last as long
Is there a download for the circuit board and the parts listing?
where i can buy this el motor?
Siema gdzie można dostać taki silnik ?
