Re: New "TSDZ2 Torque Sensor Central Motor"

A question about the temperature sensor and 8-wire controller: where do you get the +5V and GND from? The pictures on the wiki aren't very clear on that: https://github.com/OpenSource-EBike-firmware/TSDZ2_wiki/wiki/How-to-install-motor-temperature-sensor#8-wire-throttle-type it's not super clear wha...

Re: New "TSDZ2 Torque Sensor Central Motor"

Look up how an XRing seal works and you'll understand that the Oring part is actually stretched over the bearing and can't slide, its the outer lip that then seals against the inner section of where the seal sits within that plastic cover. Seems odd and contrary to a normal seal. Im having trouble ...

Re: New "TSDZ2 Torque Sensor Central Motor"

I looked behind the plastic cover and there is no trace of the seal. I have no idea where it went because what I got out was only about a third of the total diameter. I expected to find the rest of it chewed up by the gears or something.

Does it sit in the plastic cover’s lip normally?

Yes it’s smashed :( Here is a clearer shot: https://i.imgur.com/otxB9hY.jpg Do you think the big gear may have been rubbing on it? Do you have much play or wobble in the spider or axle?

Re: New "TSDZ2 Torque Sensor Central Motor"

So anyway, I have found replacement plastic covers on aliexpress: https://www.aliexpress.com/item/33009857653.html but where do you get the seals? The original seller (EUNORAU) is being an ass, saying there is no way this broke on its own, so it's not covered by their warranty, and so I have to pay ...

I took it apart, and that’s what fell out. 2/3 of it is still in place.

Is the plastic cover smashed around there too? The photo is a bit too dark to tell.

New "TSDZ2 Torque Sensor Central Motor"

Some grey seal fell out of the motor today... .. Couldn't be that the same stuff (anti seize?) that is noticed here ?

Some grey seal fell out of the motor today... it looks like it comes from behind the spider. Any idea what it is? Should I replace it?

Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

Pedal side is which pedal is down toward the ground when turning the bike on. Weight with offset is the torque sensor converting its reading to a weight in kg after calibration. It helps to check if you did it right: does the 5kg object register as 5kg on the display after calibration or is it off? ...

New "TSDZ2 Torque Sensor Central Motor"

That happens to you because you did not update your firmware to most recent version. Yes, on purpose. I depend on the bike daily and can’t afford it getting destroyed. I have read several reports of controllers blowing up with later versions. There is a rather ominous warning on the download page f...

Re: New "TSDZ2 Torque Sensor Central Motor"

My tsdz2 has behaved strangely. Sometimes gives a very good assist and sometimes very badly. I started adjusting the torque sensor. I measured its value first and it was 157. The minimum value I can adjust it to is 64 (should get to values of 25-30). Is the sensor simply broken. I have that too som...

Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

Would you consider adding a configuration option to hide the clock altogether seeing how unreliable it can be and how much it can drift if you don’t use the bike every day? I’d personally much rather not see the clock at all than seeing it display the wrong time every time. Which Version you have i...

How do you guys find the motor waterproofness? I live in an area with a lot and sometimes very heavy rain and I would still like to continue cycling in such weather.

You have to go OSF all the way. Make sure to match the display version with the right motor version of the osf

Sorry for that question, but I don't really understand that calibration procedure. First of all the ADC values vary from left to right side. Is this normal and what do I have to note? When do I have to switch the calibration value from disabled to enabled? Does enabled mean that I always have to ca...
