its kinda dumb that theres not a single picture of how it attatches to the hanger… and this goes for all hub motors and production boards… like this shouldnt be some esoteric information
I don’t think it is strange of dumb that the production boards show you how they do it. They need to make money.
But about my hub. In one of my first post, I have a video of the assembly of the hub. Everything is custom made (except the stator and rotor). I press fit the stator around my axle. The axle is screwed in the trunk(that i made myself).
@bevilacqua didn’t do that much the last time. Finished my enclosure and battery. After that, it was waiting on new stators but they arrived last week. now I need to make time to finish it

true… it isnt really strange that the production boards basically hide stuff from you so people dont go and just build it themselves…
im not sure how “Press fit” works…
is it true that you have some kind of square part of the truck that holds the motor in place?.. and i guess a bolt which acts as the axle… is this a feature of the premade stators that you had no choice on?
im actually looking for one of these r-spec/maytech style motors for a custom truck i have…
but i am also looking for hub motors that can bolt onto ANY normal paris truck or venture trucks or ANYTHING… perhaps with some kind of hex screw tightening onto it… or something like that…
is your motor either of these?
a press fit is when your hole is slightly smaller than the axle (think in 0.01 of an mm)
I don’t have a square part or something only the press-fit to lock it.
no, my hub doesn’t fit on a normal truck. it is way smaller (126mm if I’m correct). My goal wasn’t to make a hub that fit on a normal truck because a truck was a piece of cake if you look at the rest.

you mean that the truck axle wouldnt be long enough for the width of this hub motor compared to say a regular long board wheel? what if i were to cut away some of the truck hanger to expose more of the axle??
the aluminum part is 126mm, the total length is the same as a normal truck (don’t know the measurement).
If you look at my truck axle you see it is totally different from a normal truck one. so making one myself was easier.

oh wow… yours spins in the middle not just the outside?? i assume that thread screws into the truck hanger? and that tripod thing seems like it stays stationary at all times… but the mini gears on it individually spin??
Hello Frank, Where is the build in the background from? Where the stator can be seen?
Because these hubs is both yours, correct? : http://esk8content.nyc3.digitaloceanspaces.com/uploads/db2454/original/3X/b/2/b2863ff035dfae46f3df9742d0197953c8550727.jpg

that are the direct drive motors of @zeinstra. --> http://www.electric-skateboard.builders/t/first-build-diy-sensored-duel-63mm-inline-directdrive-90-mm-wheels-vesc-porn
the same hubs in the second picture are the same only with different color tires.

long time no see. I can say that I finished the project and something that I was scared of came true. The space between motor and the outer ring is too small therefore the loss in eddy current is too big. Maybe I will modify it later to (hopefully) fix it.
For now, I will change to belt drive because i want to drive this year.
i will upload some videos later

I was thinking this week what happened to this project
You mean that the cilinder that the magnets are mounted are too close to the outer wheel cilinder and the magnetic flux behind the magnets are inducing a current on the outer cilinder?

so i fixed the belt drive 3 days ago.
i bought a torqueboard truck but it was way to big so i made it al little smaller(40mm)
!
then designed mymounts (15mm alu with 4mm stainless steel)
!
!
!
!
there is some little adjustments needed but it works

That’s a long lever on the Torqueboard truck. Hope you axle won’t bend or fall into pieces …
it is 20mm shorter on both sides if you compare it with the original. so it should be fine
Why did you buy tb 218 if you needed it to be shorter? Or did you need the longer axel?
Nice thick clamps btw. You have any extra for sale?
I could not find a truck long enough, they were al 10mm to short but the tb is way too big so I made it a little smaller.
we are planning to make a batch in a couple of weeks so if you are interested, send me a PM.
Cool.It depends on the price ofc, but I pm you tomorrow and we can discuss it. You’re from denmark if I remember correctly right?
Hello Frank. I’m very interested in one of your builds, the planetary hub gearbox for a electric longboard. I was doing research on planetary gear boxes because I’m going to be building a electric long board w/ a planetary hub when I stumbled on your build. I just have a few questions. How did you get your ratio? Meshing? With the knowledge I have, the gearboxes purpose is to decrease top speed and bump up torque to the wheels…? Any recommendations as far as design or anything else? I will happily take anything. And BTW, I’m only 17, and this will be my first ever long board build. Thank you!
