    max peak power/tourque QS60V5000W 13" Hubmotor or Xiamen ZAP Erider 8kW

    Hi, two threads for you with useful information: https://endless-sphere.com/forums/viewtopic.php?f=30&t=99709 https://www.endless-sphere.com/forums/viewtopic.php?f=3&t=29902 TL;DR: "John in CR" fed such a hub with 425A (battery) and 550A (phase) @ 20s. The motor has a kv of about 18 rpm/V, so...

    Quantya Upgrade Build

    dan974, that' a lot of information and not only good news. Thank you for preparing me for what is coming up on the upgrade to 20s. I don't know if understand all of your posting :oops: but I will have a look at the brushes soon. I thought there will be no major problems as the Quantya did...

    Quantya Upgrade Build

    Hijacking boogiemate's thread, maybe he will post updates 8) Got the Quantya registered, it's now road legal, and it is great fun. QuantYEAH! With the smallest rear chainring I got, top speed is now 85 to 90kph fresh off the charger. Lost quite a bit of acceleration, will gear down again...

    Cycle analyst-can't get my throttle smooth?

    I don't think so, but I am not an expert. I got the same behaviour you described when I first tried the current throttle, but forgot to reduce the max current. Instead of that I turned down the Again parameter to control acceleration, with the result of oscillation. It took some iterations...

    Quantya Upgrade Build

    I am not as ambitious as the thread starter :wink: 100kph top speed would be nice. Commuting to work is 20km one distance, and I can charge there. 10km from home I'm in the outback (woods, gravel "roads") where the fun starts. Now the battery is 14s 40Ah, I got enough cells to build another...

    Quantya Upgrade Build

    Any updates? Bought a Quantya with a dead battery & bms, replaced the cells, mounted the longest gearing that came with it (large motor belt sprocket and rear 48t sprocket), but a little more top speed would be nice. Next step is upgrade to 20s. What kind of battery do you run?

    Cycle analyst-can't get my throttle smooth?

    If you are using "current throttle" you have to set the maximum current to the limit of your controller or slightly above (in "power settings").

    Hubmonster teardown

    Take a close look on the connector shown on the last picture. Are there numbers from 1 to 10? Pins 1 to 5 are for the first set of halls. On mine there was a "nose", a hook that secures the connector. First set of halls is on the side of that hook. Should be the cables on the right side of the...

    $14.99 72v Sunwin Controller

    i'm curious about your results. i could not get the mxus 3k working with the 72v 1500w controller in sensored mode. tried multiple self detection runs. it runs fine but i have to pedal the first meter(s), otherwise it does a wheelie, no matter how sensitive the throttle is touched. all motor...

    Adding more FETs to controller ?

    been there, done that 8) all i can say it works with an internal magic pie 2 controller, i added another 6 fet of same spec (75pf something...) to the 6-fet-controller, and a massive heatsink. just wired one fet parallel to each existing one and tried to keep wire lenght equal. worked like a...

    $14.99 72v Sunwin Controller

    I bought two 84V 1000W controllers from sunwin (one as spare) for my bicycle. The label says "SH84U35GV15T-WZ3". Both have immediate start, no delay. Stock current limit is Speed I: 33-35A (oscillating a bit) Speed II: 50-51A Speed III: same 50-51A. so Suggs may be right when guessing the...

    Crystalyte 72V problems ... new setup questions

    Andy, when you took apart your "Zauberkuchen", did you mark the side covers, how they came off? You should assemble the side cover in the same way they came off to get it running round. If not marked, unscrew the nine little hex bolts on one side cover, turn the side cover one hole in one...

    Restricting AMPS/Current/Torque!

    wouldn't it be easier to modify the throttle signal with one of these switches http://www.methtek.com/2012/07/03/universal-3spd-switch-works-with-any-controller/ was discussed in another thread, can't find it at the moment. you can easily switch back to full power when out of the mud hole :wink:

    can't remove freewheel

    das dürft' auch passen, und das gibts hier nearly matches your nick :mrgreen: btw, when i had to remove the freewheel from the magic pie, i took off the side cover of the motor with the freewheel. the axle was no longer in the way. then cut a piece of sheet metal to fit into the slots and...

    HS3570 Hotrod Project with 46T->74T Hammerschmidt Chainwheel

    crossbreak, as neptronix mentioned before, I think it's not AC, it's DC, as the current does not alter its direction. Even "pulsed" DC should be treated as DC. cheers, phil. ps: you`re still planning to run the pie in delta mode, aren't you?

    HS3570 Hotrod Project with 46T->74T Hammerschmidt Chainwheel

    crossbreak, i'm following your build thread and like to see the pie getting converted to delta. if you don`t need the internal controller board anymore, i would be interested in buying it, as you need money for your fourth bike :mrgreen: cheers, phil.

    Do many of you use Golden Motor?

    I've got a magic pie 2 rear wheel kit with internal controller. Done about 1000 kilometers so far and I like it. It is easy and "clean" to install because if the internal controller, less wires than exsternal controller. The build quality of the internal controller is not good at all. There are...
