The pure coils without inner tube:
Outer diameter: 8 mm
Inner diameter: 6 mm
Length: 6 mm
Coil distance: 1 mm
Wire: 0.1 mm
16 cylindrical neodynium magnets: 3 mm x 6 mm
Orientation of the magnets: N-S S-N N-S S-N N-S S-N N-S ....

Very interesting! I had similar ideas for a homemade direct linear actuator for RC aircraft models.
-
Grats making it on Hackaday!
-
Each coil is controlled separately. The only the ground have a a common pin.
Each magnet is 6mm long, each coil is 6mm long, too. Space between each coil
is 1mm. Cluster on the left? Nothing, only solder pads. -
Thanks for sharing! Any tips on how to assemble repelling magnets into the brass tube; Glue? Or there is some tricks to it?
-
Nice job.
I'm building one to slightly larger.
You should check out foc control. -
Thanks for posting this. Do you have an URL about how to build this. I'd like to make one too.
-
Very nice video
The inner rod is made of magnets or only copper rod can i know -
Hi again. Jus a favor. Did you use ferrite on your coils, or they are just plastic tubes with isolated coil wires wound around them?
-
How is this wired, did you use 2 coils wired in pairs or 4 coils sharing a common pin? How long is each magnet string, does it cover 1 coil or 2 coils? What is in the cluster at the left, is that a sensing coil or did you run it open loop? I am building something similar could use a pointer or 2.

Hi... Is there any new version?
-
No, sorry. To understand the principle I studied a drawing from the Nitek Tubular type S series Linear motor. The pic is at the bottom of the page.
-
them magnets must have been a pain putting them in the tube fighting each other.
-
amazing
-
Hi! I just want to make certain something! The yellow bar, the one that moves, are the 16 magnets piled one by one? Thanks
-
Holding the coils still and upright, does this have enough strength to lift the shaft vertically?
-
I was looking for info on something like this...
-
How to manage?
-
Interesting, I'm making one of those myself, but can't seem to figure out the magnetic fields and coil length per magnet pole length, do you have a good pdf or a book reference where I can learn about this? I'm assuming the magnets are axially magnetized and arranged in repelling directions? But is there an iron separator between each magnet (a yoke), most linear motors use those?

Que diámetro de alambre tiene

wow, definitiv gut,. :)
