should i aim the gopro at the fet side of the controller to capture it?grindz145 wrote:Greg, that current is fine with Halls, but once you "loose sync" on a sensorless controller, I would worry, very different scenario.
eb212 sensored. eb312 sensorless. more at lyen.comO wait is EB212 sensorless? I'm confused...
a local ebiker. i'd suggested we race before he went on vaca... to which he responded:I missed it, who is sailorboy?

well curiosity got the best of me, and unfortunately, in order to replace the spoke from the inside, it does need to be bent, just a bit... otherwise it must go thru gap between the opposite side spokes and couldn't be bent back, certainly not w/o loosening all of them. the spoke can be bent back more or less (less) straight, but looks traumatized.GCinDC wrote:...unscrewing each spoke (on the right side, that's laced on the rotor inside), bend the spoke enough to yank it out, and re-insert from outside of rotor, and tighten back up in nipple...?
Can you describe exactly what causes sync loss? You mentioned backing off of throttle quickly. Do you have personal experience with it, and what happens?grindz145 wrote:Greg, that current is fine with Halls, but once you "loose sync" on a sensorless controller, I would worry, very different scenario.

I use a micro switch, ziptied to the break leaver. that way, I can pull on the regen, and then pull a bit harder to add in the disk brake, or just pull the disk brake on its own. works like a charm.
not sure if you're asking me or Snow, but i've tested the 1 and 2 settings via programming and there's not a lot of difference. methods told me that he got fed up w/ regen with his kelly controller cause it came on like a brick going anything above 5mph. i would not like that, but i love the level i run regen via the infineons. i don't do it to charge the pack, or for any efficiency. i do it for braking, because when i'm not accelerating, i'm braking, or about to...gensem wrote:have you tested strong vs weak regen?
Whats the efficiency on regen, 75%?
this comment actually makes me want to implement variable regen.Skippic wrote:Forget regen, just get good brakes.
not yet. but thanks for asking. i searched on 24-90v and found the thread! unbeatable deal. just have to wait a month or so...Duc998 wrote:you running any lights GC? I'm interested in the one from ebay 24-90v 12w and hoping I can tap into the aux of my CA-DP.
Greg, if you want to circumvent the washer issue, JRH had some custom spoke nipples manufactured from Sapim that threaded into 12&13 guage spokes, but the head flanges on the nipples were designed larger than a normal bicycle nipple head to fit mc rims. This was to avoid the washer issue. Invariably they will come loose again...GCinDC wrote: the obvious challenge with this wheel build is securing 12g (2.6mm) spokes with (5.5mm) butt ends in giant 8mm wheel holes:dbaker accomplished it here with two washers, both of which bent to the shape of the hole: i have no idea where he got the oval ones.
first off, i was able to salvage the disk adapter - no idea where dbaker got it... i'm thinking i will thread on and jb weld to side cover. i do see justin's got spares of the newer (flat) side cover, but the MC wheel is on an older 9x7 with the rounded sides and the side covers are not interchangeable. i do have (dirty) spare side covers. and rather than redrilling, i'm thinking about sealing the covers on and squirting in snake oil.knoxie wrote:broken side cover disc mount
thanks, len. i'm sure JRH is tired of hearing from me. he told me he's got (or will have soon) nipples to fit 6.4mm holes, but these rims have 8mm holes...Lenk42602 wrote:JRH had some custom spoke nipples manufactured from Sapim that threaded into 12&13 guage spokes,
Looks the same as the ones Grin Tech sells.GCinDC wrote: first off, i was able to salvage the disk adapter - no idea where dbaker got it... i'm thinking i will thread on and jb weld to side cover.
Maybe you should try a moped wheel setup, might be a better compromise.GCinDC wrote: i'm definitely not crazy about using washers. i never even rode in the rain, and can see some rust starting. what's ironic is that i got the wheel hoping it would be indestructible, but because of dish issue ended up constantly adjusting it and doing more maintenance than a 26 rim!
i wish it weren't so expensive to ship these motors/wheels around because i'd much rather have them built by a pro. might be worth it next time.
