My main question is about PC USB-based oscilloscopes. The rest of this is specific to my problem(s) and may be overlooked.
I'm using cordless drills to power electric bicycles. I have one built. It works but is underpowered. I am building a better one using a DeWalt DCD995. Some nice electronics included in that drill, a stout (very tight turning) brushless motor with a controller.
It has a few inputs from the speed switch and clutch.
It has 5 data/signal outputs from the controller to the motor. One wire is purple, the other four wires are black.
It also has three heavy-duty wires going to the motor. I've been told that the drill uses AC, so maybe that's what the extra power wire is for, I dunno.
I desperately need to disable some of the motor's functions, so I need to know what the various wires do. Since it's probably a DeWalt specific motor, looking for data would be a waste of time?
The three heavy-duty wires... Do you guess they control any of the functions or are they simply for supplying power?
Thanks.
