Testing some software mods on VESC 100 250 Based paraglider-hanglider winch to improve safety. 

Howdy, the holes were more just mucking around in fusion when I was drawing it up. To really get heat sunk out in that area you need to add statorade to the air gap as the heat often stays localized to the stators and can't conduct easily across the airgap to the rotor. This is now not much of an issue as in my new full version I simply just got the biggest motor(12KW QS rather than the 3kw in this video) with the thickest windings and heat seems not to be a worry now. The line guide is just a yacht fairlead.

@@lukef9470 did you anneal the aluminum before you bent it to make the fairlead?

@@embededfabrication4482 Oh yep something I'm a little proud of there. So I tried many ways of doing this including annealing and not annealing, pipe bender with a few failures. So it is 25mm OD and 1.6mm wall thickness. That one in this video is actually not that good, on my full big winch I got a perfect bend. After many different attempts I found it very simple. So do not anneal the metal, I cant comment on thicker or thinner wall thickness tube but on 1.6mm no need in this specific case. In the part of australia where I live we have very fine beach sand. I got a bucket of nice dry sand and a funnel. I filled up the entire length, tapping it to settle properly as I went, sealed ends with duct tape nice and tight. I then made a simple jig out of ply wood sheet and a block of large dimensional lumber 25mm thick(I butted a couple together to make up the span of the radius. I just drew out the radius of my bend with a cheap timber compass and used a jigsaw to cut the bend shape. I then attached it to my bit of plywood, then used a g-clamp(kind of doing what a pin in a pin bender does and just bent it. Very repeatable.

@@lukef9470 I'm thinking of trying pvc pipe with wood dowel inside to make it rigid at the pivot, can counterbalance it too maybe, who knows, wobbling around a bit could wind the spool more evenly, my pivot is on a bearing so it's really easy to rotate.
