That's some serious current for sensored operation. Be careful if you lose sync! Get off the throttle quick, or else bye bye mosfet ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
i've had a pair of the eb212 controllers programmed with those settings since Nov 2010, and i can assure you, i've not been careful...grindz145 said:That's some serious current for sensored operation. Be careful if you lose sync! Get off the throttle quick, or else bye bye mosfet![]()
should i aim the gopro at the fet side of the controller to capture it? :lol:grindz145 said: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...GCinDC said:...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 said:Greg, that current is fine with Halls, but once you "loose sync" on a sensorless controller, I would worry, very different scenario.
sn0wchyld said:it does have a pretty notable warming effect... ive got my regen on a separate switch for that reason... so if i'm racing round i can just heat up the brakes, but if im on a long downhill or riding for range then the regens available when needed.
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 said:have you tested strong vs weak regen?
Whats the efficiency on regen, 75%?
this comment actually makes me want to implement variable regen.Skippic said: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... :lol:Duc998 said: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.
GCinDC said: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.knoxie said:broken side cover disc mount
thanks, len. i'm sure JRH is tired of hearing from me. :lol: he told me he's got (or will have soon) nipples to fit 6.4mm holes, but these rims have 8mm holes... :?Lenk42602 said: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 said: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 said: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.
