    Self-learning controllers

    Hi Jeremy, Thanks for the insight. Do you happen to have a link to anyone who has reverse-engineered an example schematic for the setup you describe? I know there's this: http://www.avdweb.nl/solar-bike/electronics/ku63-motor-controller.html but I don't think it's the exact controller I have...

    Self-learning controllers

    Jeremy, Sounds pretty much like what I've discovered through messing with these things over the past year or so. I most like the self-training Halls feature and wish it can become prevalent on more legitimate controllers like Kelly... or someone design some real hardware around the processors...

    Self-learning controllers

    Hi all, Frequent reader but rather infrequent poster here; I operate primarily in the e-scooter and go-kart (and other weird rideables) domain, not so much e-bikes. I come to you with a request for feedback on Chinese ESCs which have a 'self-learn' mode where they can automatically recognize...

    Turnigy CA120-70 8600W Brushless Outrunner (100c eq)

    Hmmm, on further inspection (i.e. filing a small part of the can, like keying the paint on a brand new car, and also using a small magnet to test portions of the can) I'll retract what I said about the rotor. It is indeed steel. I was mistaken because all the motors I've built had very thick...

    Turnigy CA120-70 8600W Brushless Outrunner (100c eq)

    The part that sticks out of the front is 10mm. The rear, however, is a 12mm. I have yet to take the motor completely apart, but I guess at some point it reduces. I threw it on a 100A Turnigy controller that I had sitting around.

    Turnigy CA120-70 8600W Brushless Outrunner (100c eq)

    The lack of steel does! Half the flux in that motor is leaving and never returning. I suppose one reason they did it that way was to increase the Kv to something an R/C modeler would find useful. We EV hackers won't mind Kvs in the 30s and 50s, but a plane spinning a prop would find that less...

    Turnigy CA120-70 8600W Brushless Outrunner (100c eq)

    Hey all. We just got this thing in today and spun it up. I must say, it's the coolest looking motor that Hobbyking sells. It's all blacked out and anodized - very much a departure from the chrome cases of the others. But, in classic HK fashion, it's a little lacking in legitimacy. The rotor...

    What is this shady Ebay controller?

    I think I'll throw down for one or two and pop 'em open.

    What is this shady Ebay controller?

    I stumbled upon this while looking for the 72V/45A units from e-crazyman. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=170456224894&viewitem=&sspagename=STRK%3AMEWAX%3AIT Looks superficially similar, but those thin phase leads make me a little concerned. Anyone seen these...

    DIY outrunner instructable

    Good to see that my writeup is being passed around. You all are welcome to scan it for any theoretical errors or things which could use more clarification. Though keep in mind that I had to distill things down pretty far to make it more accessible.

    Reversible BLDC control solutions?

    Thanks for explaining your question better. I'm used to dealing with current limiting DC motor controllers, so "phase" and "battery" were less distinct. Given these differences, I would err on the side of previous experience and say 100 amp battery current, which posters have already directed me...

    Reversible BLDC control solutions?

    Hello, I'm more used to dealing with maximum current as a function of maximum acceptable controller temperature. I personally prefer no active current limiting on either end by the controller itself (that or an internal limit far beyond 100A, or programmable to be above that). I have had...

    Reversible BLDC control solutions?

    Greetings all, Been reading for while and never posted, but you guys seem like a crafty enough bunch to point me in the right direction regarding my controls dilemma. I'm seeking a reversible BLDC control solution that is not a Kelly. I'm kind of sick of dealing with those things. Now, I see...
