Magnetic Gearing for Power Transmission, Propulsion, Space, Electrified Aircraft EVTOL
Magnetic gearboxes were proposed almost 100 years ago. Magnetic gearboxes are contactless mechanisms for torque speed conversion they represent no wear, no friction and no fatigue. They need no lubricant and can be customized for other mechanical properties as stiffness or dampening. additionally, they can protect structures and mechanisms against overloads limiting the transmitted torque.
They provide intrinsic anti-jamming properties and there is a clutching effect if the applied torque exceeds a limit therefore protecting the output from overloads. This effect is completely reversible and no damage or wear is produced while operating.
The motion direction is also reversible with highly...

Preparing for some winter weather approaching as we're running low on firewood and expecting several inches of snow in Tennessee. Our wood stove helps heat our house and definitely offsets are electricity costs. just last year we got Mini Splits installed in the house but before that we solely heated our house with our wood stove for over 12 years
Slantern - Cumberland Trail // EPIC Tennessee Summer Bouldering
Просмотров 9810 месяцев назад
An incredible boulder on the Cumberland Trail. Aptly named, "Slantern" because all the holds are facing the wrong way, making the climb unusual and difficult. The climb takes a full 2 minutes to complete, and is an endurance test to complete the last boulder problem. Figuring out the sequences was quite challenging, as well as working this problem during the hot humid months of July/August/Sept...

Where did you get the wooden base box? I would love one for my RX607z too! Thank you for your help!
I'm not going to criticize the magnetic gearing but I will point out that speed is unregulated on that power tool, under load like that you are at a much lower rpm than the dial indicates. A non-contact tachometer would be needed to measure actual speed. Neat demonstration however.
These results are encouraging. Bearden speaks of drawing off power without destroying the dipole; I looked deeply into Floyd Sweet 's circuit and believe he was doing that, separating common mode currents from differential mode, with a pair of bifilar coils. The common mode currents would freewheel to continue running the resonance, while differential currents would be extracted as output
all this explanation just to make yourself look dumb... just for the views i guess
You are transferring no power, so it has zero efficiency. Sure, the little wheel is turning faster, but that is doing nothing but overcoming friction. drive something, like a generator, so you can electrically load & test the output power. i bet you can't get more than 10% of the power in, out. That's why 'magnetic gears' aren't used to transmit power.
I keep watching Battlebot shows hoping one of them finally uses a magnetic coupler for their heavy flywheel type weapons to eliminate the belts and chains that tend to cripple their bots when they fly.
Where is this exactly?
Hi I also am lookin for a foot pedal & power cord any help would be greatly appreciated . Wondering if it can be replaced somehow with a different one? I wrestled the back panel off which seems to be a challenge to do didnt berak it😂 the electric configuation is above my skill any help with that also would be great Thanks
Glad this worked for many. My journey still continues 😢
So did u fix it
@@tihi_dom I did. My SD card was too big. I guess to format correctly it can't be bigger than 32 gb.
@@TomiBoi5 oh okay ill try that thanks
@@TomiBoi5 THANK YOU! u rlly helped me and saved me rlly much time and energy lol. It worked. Thank you again and have a nice evening bro
@@tihi_dom Glad I could be of service! Thank you, you have a good one as well ✌️
I was about to lose my mind trying to figure out how to get inside this machine I picked up on the curb 😅 thank you!!
Hello there, i was looking for your results and application of the MEG generator, how did it go?
Much appreciated. Solved my problem. Thank you.

They say you need a high voltage diode across this bucking coil Transformer along with a capacitor. The output was supposed to be eight times the input.
I have 2 of these but the 6000 series extension table I got on Ebay doesn't fit it. Am I doing something wrong?
There's a different design between the early and later 6000 models

I just broke my alternator belt at 5am sitting in a parking lot waiting for things to open and help to wake up. Thank you for the video!
Where can I find the file?
Awesome so where can I find the STL? been looking all day and all have been removed or just not there.
This did not work for me. 🤷♂️
Nice to see repair videos like this, but... 1. Get a tripod, this shake is making me sea sick. 2. No fingernail polish please! Those painted nails are very distracting as they flutter around. I tell this to women all the time. DIY videos need focus on DIY not hands, hair, nails, faces, or music. Wear gloves so we don't have that distraction. See it from the viewer point of view. 3. Better lighting for dark insides. Headlamp would work great. 4. Read the manual on your own time please. We are here to benefit from your expertise, not novice learning.
My friends and I threw a party there after prom 2011 we were behind the "Abstinence Rules!" Graffiti have been struggling to prove to people that it was real the Falling Water knockoff was pretty unbelievable I must admit
Hi, what did you get the service manual?
No, didn't work
Hello I just acquired a beautiful 6000 series Viking machine. I live in NJ. Where would I take this to be repaired. It works but I’d like to get it serviced and cleaned. Any suggestions? Would be greatly appreciated.
Knob...sorry.
I have a 6270 that I am unable to turn the stitch selector know. Can you help me.
Some random stranger just gave me one of these. It was her mother's. She would not even take money from me. It works and has tons of accessories. I feel extra blessed to see your input on the machine. I will have to check the knobs you mentioned.
In the last equation should the 100 be 1500 ?
Thanks for this. Just bought a 6430 and getting it running again.
Me too I’m In NJ and not tech savy. Is there anyplace I could get mine cleaned up and checked over?
any video or help in installing servo motor on the omega walking foot?
How'd they hold up (comfort wise). Thinking of getting a pair?
You are too rough !
Sounds horrible
Does still not work
I just purchases this machine new in the box never been used will you be able to bring it to life I imagine she is stiff she was born in 1979. Receipt in the box!!! I need our guidance
Jeff. I just purchases this machine new in the box never used receipt date is 1979. Are you willing to bring it to life. Or do you think I could do it myself?
Thank you!!!!! Make more content please!
i know this is an old post, but where did u get the core from? and the function generator sw?
Updates, did you get it to work as intended?
Hey man, what machine did you use for winding ?
I have a Viking 6000 Series model 6030. The machine needs work. I have the cams and operating manual, is there somewhere I could sell it in California?
Where do you sew your Husqvarnas? I have one of these, but I'd really like another.
Yep - 99% of this was wrong.
After 4 years this video still helped ! the only down side to this was all of my previous files i had saved on the printer was deleted , but now at least my new prints shows up and works :)
this fellow has no idea what he is doing
Evidently, and luckily the tree was balanced evenly, it could have fallen in any direction. The notch was way too big. Do NOT copy this guys technique, he only had about two inches left for his back cut.
