Hi,
i have a Pedelec (Winora Town EXP v2 with TranzX PST).
My bike broke down and nobody is able to repair it.
It seems, that there is a problem in the motor controller, which is getting information from a sensor, which is checking, if you are pushing with your feet and generate the signal for the motor - i heard, that some kind of PWM is involved. VidMate AnyDesk https://mobdro.onl/download/
The motor itself seems to be ok. There is no option for me, to get a new/used controller and i dont want do trash the bike....
I thought about removing the motor controller, setup an arduino and have the motor signal controlled by a potentiometer. Anyone knows, where i can find more infos, how to find out, what kind of signal is used and how i can reproduce this?
I am a bit known to arduino, created LED Matrix, remotes etc, but i have no clue regarding the signals.
If you do not have schematics, you either need to do more research into the problems that the unit has.
did you validate that a proper signal is being input from the sensors?
is there some sort of test or bypass circuit ?
if you find that fixing the existing is too great of a problem, google with the word arduino
arduino bicycle power controller
or bicycle motor control arduino
based on simple controls, you have a device that 'sees' an input and based on the input, it then creates and output.
with no input, you get no output.
if the input wire is bad, or connection is bad, you never get the signal.
sometimes it is that easy of a fix.
If this is a pedal assist, so that you have to pedal for it to work, there are a few ways to make your own controller.
The other half is the DRIVER, or the circuit that handles the high power and not just the signals.
in order for us to help you, we would need to know more about the motor and the batteries and the motor driver and the motor controller, and the inputs and the sensors......
