Previously Unlisted: Industrial Automation Oddware. Behold the resolver, how it works and what it does. Is it better than an encoder?

That looks for all the world to be a draw wire sensor for measuring lengths. Incidentally, if you can point me to another of those Cockford-Ollie mugs (I had one but it got broken) I would gladly pay for it and make a donation to a charity of your choice far exceeding the cost of a coffee mug. It was given to me as a gift and that person has since passed (perhaps from the chow mien or maybe it was the egg rolls…).
I ran across one of these running a folder-gluer machine. It was connected to the feeder unit on the front of the machine. When that thing craps out it sends you looking for gremlins in other places. Had to replace it twice, found out it needs a little bit of shock obsorbtion
Is rms significant if the waveform is somehting other than SIne (or cosine)? I think, forty years ago i learnt the derivation of root mean square and it was reliant on the mathematical function..
You must be a freaking genius.
Do you have any videos from the Bartending Robot
idk what math you did but on a milling machine with a 4 threads per inch lead screw, that means 4 full turns per inch, so 1440 degrees per inch. You said at 10 bits you get roughly 0.2 degrees, thus
1440 -> 1
0.2 -> x
x = 0.2*1/1440 = 0.0001 inches
That's a tenth – 2.5 micron, I doubt most milling machines even have that much precision, so I'd say about good enough. Plus you can just gear it down, a 2.5:1 ratio would get you to 1 micron, and those are dry air seal tolerances, you don't see that everyday with traditional machining. Thanks for the vadjeo!
I've been an avid watcher of your vids for a couple of years now and all I can say is that I still have no fecking clue what you are talking about half the time. When I say about half the time, I mean all the time.
All I'd like to say is that you, sir, are an educator. Fill every school, college and Uni with copies of you and the world would be a far better adjusted shit heap than it currently is. In my work I need to be able to communicate with folks who run the entire spectrum of intellectual/educational levels and if I were able to do what you do in the way that you do it, then my work would be so much easier and I would be more successful.
Keep doing what you do and do so well. The world is a better place with you in it.
Take it easy and stay safe matey.
Couldn’t you change out the gear on that resolver and change the resolution?
Specifically I’m thinking about your line “20 Thou is too much for a Bridgeport milling machine.”
If you made that face gear smaller you could get a more accurate rating, potentially even enough to home-brew mechanize if not CNC the Bridgeport.
I doubt you have much inclination for such a project, but I figure it’s an interesting thought experiment
with the 2 secondaries being able to take 1024 positions… Wouldn't it be a resolution of 1024², or 1,048,576 points of position (not 2050)?
clock spring
16 bit in industry. Also sense direction of rotation by comparison of which coil is falling and which is rising.
Transformer = torque converter. Brilliant! Never thought of it that way.
Dave is his name lol
As long as there's stuff tah take ay-part uncle Bumblefuck'll always have something to do.
Have you had an increase in unsubs since your last video?
