I'd have one more quick question pertaining the internals of the S06S controller. What function serves the large capacitor just behind the shunt in lying position (at the left side on the pic) ? What if this cap is missing or without connection ? Thanks! Source: tony16 -...

Thanks d8veh for the insight. Do you possibly know of a 9-FET Sine Wave Controller with max. amps around 18-20A ? Somewhat more powerful than the rather wispy 6-Fet S06s but more compact than a S12s 12-Fet sine wave controller

Sorry for the wait. Short version: On the one hand the S06S runs really quiet and smooth with my Q100H 260rpm hub - so the troubles it had with the KU93 new rev. controller - motor cutoff at high RPMs and noisy behaviour of the Q100H - where all controller related! S06S/Q100H combo @ 48V works...

Would have an additional question pertaining the S06S controller with original FETs and caps. (no frankenstein mod yet :mrgreen: ) Does it have a temperature fuse inside or what?! Using it with Li-Ion NiCoMn 48V batt.pack, S-LCD1 display, speed sensor and a Q100H 260rpm hub (52V+ if...

. will test cruise function via the wire for sure with a S06s controller, coming from a new rev. KU93 controller where it works ok with the cruise control button on a Wuxing-type half grip throttle. That is if those bmsbatt. folks settle to start shipping it eventually :roll:

. Ok, so then this possibly needs a momentary pushbutton with latching functionality to make it work as cruise control switch with S-series controllers with cruise wire input ..

. One can connect a 'cruise control button' switch to the cruise wire also and engage or disengage cruise function if needed. It works sort of like a momentary push-button switch. Such cruise control buttons often come accompanied with half/full or thumb grip throttles. In case cruise is engaged...

I checked thoroughly all the wiring - phase cables and hall sensor connections - and all is working ok. I even tried all combinations of two phase wires only connected and the motor did not work at all with that configuration. So in essence I reckon my shutoff problems with Q100H 260rpm and...

And so where did you hide the LCD display, dont find it on the pics. It isnt possibly inside the frame also, is it ?! :wink:

Hi Fellow, thanks a lot for the detailed report and pointing out some good and some bad news! The point with the 22km/h speed limit if no display used would be really bad news. :shock: Can you explain a little bit more - with the display you can set the S06S controller to max. speed and max...

Thanks for the valuable info fellow. Just recently I did test my Q100H 260rpm + KU93 (new version) in a sensorless test drive - and it was like catastrophe. Every now and then the motor would not turn on at start up or after freewheeling cause the rotor seemingly being in a stalemate position...

To partly answer my own question, e-crazyman mailed me that the mentioned 48V 15A controller is having 75NF75 fets against the IRFB3077 with the Infineon controller. 75NF75 obviously having significantly higher Rdson (13 mohm!) compared to the IRFB3077 fets (3.3 mohm !) so the Infineon type...

Hi d8veh, do you have the 260rpm version of Q100H or 201rpm version running with the KU63 ? My shutoff problem occurs with Q100H 260rpm version and KU93 at high rpm regards ps. "All my present bikes that I built can be seen here: http://www.pedelecs.co.uk/forum/members/d8veh.html" FYI...

.. for low current applications ~15A max. are there any noticeable disadvantages of the e-craze 48V (6fet) controller compared to a IRFB3077 Infineon 6-fet Controller like from EM3ev, other than the infineon being programmable ?

Recently had a brief chat online with Jack from bmsbattery whether KU63 is compatible with new Q100H hub motor and if not why not. Answer was no not compatible and it would be too difficult to explain :roll: but basically its too slow for Q100H. Asking if conventional Q100 would be compatible...
