I have been searching in the www, but most displays I saw there have got physical buttons, which can be used to make settings. The display needs to "know" the relation of wheel rotation speed to motor rotation speed, This is of course related to the driving speed, but for displaying this speed, The speed signal from the motor indicates just the rotation speed of the motor, I guess. How shall I know which of the 6 cables of the display serves which purpose?įor being able to show the correct speed, there must be a possibility to set the wheel size and transmission rate. The display have to be powered directly from your battery " Only the speed signal need to be connected to the No.8 wire of the controller " Display is not pluged directly to the controller, it have to be working with your outer electrical system. They also answered my question about the display, but not as I wished. Now, after I got the controller/motor/throttle combo working, I received an email from QS,Ĭonfirming that I just need to put together the 6 wire plugs of Motor and Controller, I guess I could eliminate the axial tolerance by adding shim plates-but the radial clearance ? The sprocket which came with the motor sits very loosely on the shaft.Īs well axially, as radially, there is way too much tolerance/clearance (not really sure which is the right word). I already found a mechanical thing which I don't like:
Now I will have a closer look at the settings, and then the serious (but more familiar to me) work will start:Ģ) putting the motor and the controller into the frame Therefore again MANY THANKS to all the helpers ! I carefully turned it more, until up to 4,5 A (what resulted in a motor rotation rate of close to 3000 rpm), without any signs of weakness or failure. In this "idle" state, my power supply indicated only very low power consumption (just about 0,025 A), so I dared to turn the throttle - and - tataaaa. the angle was already to "85" as it should be. The software still looks kind of crappy on the smartphone, nothing fits, and the screen orientation cannot be changed. So today I connected the necessary cables, as " Dui, ni shuo de dui" suggested, and I connected my source PLUS to "NC".Īfter connecting the "PWR" wire to the source, too, the bluetooth thing indeed started blinking,Īnd I could connect as well the smartphone as the laptop. Indeed the screw labelled "B+" was fixed, and the one on "NC" was loose. I also think the points " thoroughbred" made about the "NC" and "B+" connectors are reasonable.
