Nice work on the bike man! and nice drops however it was funny you know last night I was watching the video thinking that's cool but I wonder how long that thing will stay together with all that power and off road rough stuff? Sensorless would be a good call I reckon for off roading, you of course still have the problem that the magnets can come loose with all the heat and vibration, not to mention the stress on the axle from the jumps (pretty sure with my weight I would pop an axle on one of these) ..........................
yea im starting to get seriously worried about my own HT... after seeing one with a popped axle etc its not really confidence inspiring... time for on-frame motors!
where the heck is that pic from? not exactly subtle but a nice looking bike!

thanks, methods. will get to it tonight.methods said:I am on the run right now, but if you were bored I would try these things:
sand away that epoxy
Get down to the three hall pins
Confirm ground is still connected
Confirm 5V is still connected
Determine the failure: Open or closed. Measure from hall out to ground.
Controller hooks each hall leg to a pull-up resistor. When hall is triggered it "pulls down" the line (open collector output).
Measure each of the three hall lines (at the connector) to the stator assembly to make sure none conduct. Nothing should have any conductivity to the stator housing.
After that... I would look at the hall to make sure it was the part number I thought it was.
Then after we waste 30 minutes dicking around... just pop it out, pop a new one in, test, and re-assemble.
Halls are cheap and easy to find.
I will gladly loan you a 72V 40A sensorless if you want to make your own decision. Everyone should have one for a backup IMHO - but I would not run it as my primary.

Wireless temperature control for hub motors.

methods said:...moving our limiting from the controller to the hub is the next level. Why control your system with a fixed current limit? The real limiting factor is HEAT and that is the only thing we should use to limit our performance...
i wondered who would notice... :lol:Hyena said:Nice FAG bearings What else would you name something has a tight hole and is designed to have a hard shaft go into it :lol:
tiny pinch. doubt there's a cut.methods said:Does not look like a cut-wire issue but best to be sure.
RTV?methods said:GOod luck getting them back in. My advice is to get every last little bit of RTV out of there.
next step. just gotta find my penis drill bit.methods said:Drill some holes in that bad boy and let the steam float away.
that may be fine for the spokes, but i'll need bigger nipples (or lots of washers ) for the next upgrade i'm working on:methods said:Just like pushing for larger and larger spokes when all we need are high quality 14G stainless.
Doh! what kind of wires are these that they'd crack like that, all the way to the connector!methods said:While you have those wires out give each one of them a good tug and rustle them around a bit. Does not look like a cut-wire issue but best to be sure.
safer not to run it at all. breaks down all the time. :lol: lol. just kidding. advice to new hs3540 owners: drill at least one hole, easy if you remove only side cover w/o wire. spray in anti corrosion stuff, and don't pull more than 3kw until you have a heat sensor... if i'd only done the same!deecanio said:anything else I should do before I run mine?
my old comfort bike had plastic pedals and i nearly killed myself when i hit a bump, the foot slipped off...you have the pimpled flat mtb pedals as I do but do you find they are useless in the wet?
well, you can't wear polka dots and stripes... but true, trainers, or running shoes here, have lousy grip for bike pedals, in my experience. i'm usually commuting and my work shoes have excellent grip since they're just flat rubber - in fact i should check 'em for holes.. but something flat bottomed better for sure.need to know if I need matching trainers to grip? What do you use for footwear?
