Re: New "TSDZ2 Torque Sensor Central Motor"

Thanks!! that was the help I though I would need. I will look at that source files and try to play with them as I like your design, HOWEVER, I plan to use like 1/3 the screen, at bottom, for a graph where a variable is shown -- this is something I want much and I think would be really great to have...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

You are forgetting about mass and inertia, at standstill there is max torque with no ability to transfer that into motion momentarily, once rolling some of that torque is immediately transferred into forward motion which limits the amount of torque on the gears. Also consider that max torque is at o...

Re: New "TSDZ2 Torque Sensor Central Motor"

My unit was a bit too noisy to begin with but within about 100 miles of use it has quietened down to about the same levels as my friends 2016 Haibike. Give it time and bit of mileage and the gears will bed in. Certainly though the Bafung series are the quietest motors of all, even the Bosch and Bros...

Re: New "TSDZ2 Torque Sensor Central Motor"

Its one of the great anomalies of Ebiking, when you get a bit of power you just want that bit more. But that extra oomph has to come from somewhere and that's the battery. Certainly from my experience the average speed of a ride tells a lot. My average rises from kph to almost the same in mph if I u...

Re: New "TSDZ2 Torque Sensor Central Motor"

There is a whole host of reasons to use a simple blue tooth module connection between the motor and a suitable mobile phone. The two main ones for me is that I already have waterproof covers and mounts for my Iphone, as I already use it for mapping and route finding. And the other just one display w...

OK so no takers on the springs beneath the non reciprocating part of the Torque Sensor. Does anyone have a photo of that area so that I could reference them against something.

Casainho Before you contemplate using a colour display in the day light, do check that you can see the display in sunlight. Most colour displays become very weak in sunlight and hard to read unless you use a lot of power to illuminate the display. We did a huge amount of work on a colour display giv...

Re: New "TSDZ2 Torque Sensor Central Motor"

Guys, just be careful on how much you wish, sometimes simple displays are far more informative than a lot of displays and remember the more we ask of Casainho, the more time he has to code, the less time he gets to enjoy the spoils of his work.

Noise is not so great. The BBS01B is a lot quieter, especially under full load. Bit disappointed here.

Cheers
Once you've done 50Km or so the motor quietens down quite a bit ( or perhaps you just get used to it ) and I find mine just a tad louder than the Bafang.

Re: TSDZ2 speed sensing or torque sensing issue?

I guess there are a lot of these motors in service, but the number of failures we hear about is a bit of a worry.. They are obviously not quite as reliable as you would hope. Dave Mmmm very subjective, take the Bafang series, some millions have been produced, we talked about how un-reliable they we...

John, where can you confirm to 100% accuracy that what you are saying about the gear mesh is indeed incorrect. The only place I have seen it mentioned is on a web forum from an un-known writer whose skill on these matters has never been tested by their peer group. Be careful, you are coming across a...

Re the wiring, one of the pitfalls of all Ebikes is waterproofing the cables.

Re: New "TSDZ2 Torque Sensor Central Motor"

Its the cable that's needed, I'm surprised that a non OEM unit is not yet available. The software would follow pretty quick once a cheap source of interface cables were made available.

Re: New "TSDZ2 Torque Sensor Central Motor"

You should be able to monitor your temp rises against Watts output and also see the time for the casing to cool once the power has been reduced, from that you must be able to work out what most units can handle and build into your software some sort of rough approx. safety factor. By the way Casainh...

Guys, we need to be a bit more pragmatic about what power we can continuously pull over time extended periods out of the TDSZ2.

Bought a second hand engine which the owner seems to think the torque sensor has failed, any body have any checks to verify this before I buy a new torque unit.
