Re: 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 only 963km...

Re: 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 until the...

Re: 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 anothe...

Re: 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?

Re: 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").

Re: 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...

Re: $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 ...

Re: Restricting AMPS/Current/Torque!

wouldn't it be easier to modify the throttle signal with one of these switches

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:

Both current and voltage indeed alter it's direction! A BLDC motor is nothing else than a synchronous machine or PMSM. The "BLDC" term is just for marketing. In fact it has nothing to do with DC at all. Read for instance: http://www.control.com/thread/1026172925 crossbreak, you're right. ...

Anyhow, aren't you building something illegal already? The idea is to use this with an "experimental license". You can get a red license plate here in Germany for such purposes. Still, I have to take care about legal issues like the 50V AC. 3-phase AC is still AC. I'm not sure yet how our...

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:
