New "TSDZ2 Torque Sensor Central Motor"

[Kovko]

Dobrý deň, mám otázku ohľadom ovládačov.
Zatiaľ som mal dva 36v motory TSDZ2 (verzia pred B) a dobre ich rozoberám... Vymenil som modré ozubené koleso a ložiská a podobne.
Práve som si kúpil 36v TSDZ2B, ale je uzamknutý. Čokoľvek urobím v nastaveniach displeja VLCD5, zostáva to obmedzené na 25 km/h.
Môžem to obísť nastavením veľkosti kolies na 14 namiesto 27, ale potom sa môj rýchlomer a počítadlo kilometrov znížia na polovicu.
Takže…
Mám náhradný ovládač 36v 15A, kúpený pred pár rokmi a nikdy nepoužitý.
Mám tiež ovládač odstránený zo súpravy 36v 500w a ten je 36v 18A.
Môžem vložiť niektorý z týchto starších ovládačov do nového TSDZ2B?
Viem, že tie staré ovládače sa dajú odomknúť, čo by vyriešilo môj problém. Sú však kompatibilné s verziou B? (Mám podozrenie, že sú.)
Za každú radu vopred ďakujem.


Trochu viac informácií… Moja batéria je v poriadku až do 20 ampérov, takže dúfam, že je to v poriadku s 18 ampérovým ovládačom.
Nechcem robiť veci s otvoreným zdrojom. Používam mac a neviem nič o programovaní a tak ďalej. Viac kľúčov a maznáčikov.

Na VLCD5 nastaviť veľkosť kolies 14 a 1 magnet.Na zadné koleso namontovať 2 magnety.OK?

Symptoms:
The pedals/cranks are slipping; when pedaling forward they don't 'connect' and the chain doesn't move (see video).

Same problem just came up on our TSDZ2B, after 18 months and 1600 miles, Pedals rotate round and round if I get the clutch slipping. Slipping clutch in the big crank gear. Instead of pswpower. i'm buying a new gear/bearing from another aliexpress seller to save a liitle money. May regret that.

Did you have much problems taking off the old gear. The PSWpower video uses a special puller. I may have to make one.

I have taken the big gear off twoTSDZ2B motors and it has come off very easily. No special tools are needed. I've just screwed two screws into it and used them to lift it out. Also the inner motor comes off much easier than the TSDZ2 motor.

It seems to me that a rebuilt big gear is not a good solution, it breaks down more easily.

Did your TSDZ2's go a greater distance than your TSDZ2B? If so, that's disappointing. What do you attribute your TSDZ2B early failure to?

Must have been a crap bearing on the TSDZ2B. It's actually 14 months and 1600 miles. Her bike is ridden in OSF/cadence mode at 12-13 mph, so there's been no stress on the pedals or crank bearing. My TSDZ2 bike is OSF too, but gets a lot more pedal force. That one is 24 months and 1800 miles.

I suppose the bearing could have seen water damage, but we don't ride in wet conditions. One exception was a short ride on a sandy beach (fresh water) last August. Had a lot of sand on the motor afterwards.

.She has another ebike to ride while I wait for parts, but she really liked the way OSF cadence works.

I thought the TSDZ2B was suppose to fix crap bearings that plagued the TSDZ2? I guess TS did a crappy job huh? My TSDZ2 has almost 1000 miles on it now. Within the last 100 miles I started to notice a clicking sound from the motor that follows the pedal stroke (1 click per stroke). It does not affect the performance of the motor, just a minor annoyance at this point. I am not going to rip it apart to find the cause. Continue riding and see what happens next.

This clicking noise has been really bugging me. Anticipating it's the sprag clutch bearing, I ordered a replacement but have not installed it yet. Couple of days ago I took a wired ear-set from my iPhone, used duct tape to fasten the mic in contact with 3 different spots on the bike and made audio recordings of each.

1. top of the motor
2. seat tube by the chainstay
3. rear wheel dropout

Playing back each recording I found the clicking noise inaudible at the motor. Audible at the seat tube but not very loud. Very loud at the rear dropout.

So the clicking was not from the TSDZ2 but from somewhere in the rear!

Getting back to our TSDZ2B issue, it appears to have been fixed by oiling the inner sprag clutch on the TSDZ2B. It's been a month and ridden 16 times and hundreds of miles without slipping, The pedals were pretty stiff when new, so maybe it was semi-dry and the little sprags were cocked backwards and not grabbing,

Is there more information how to oil TSDZ2B sprag clutch? Is there really oil and not grease?

I'm just an ebike tinker. I used penetrating oil (not WD40) because that's all I had. I did buy some Mobil grease to regrease the gears, and when I do that in the future, I will see if I can force some of that past the dust covers over the bearings,

For an easier access you can remove the dust cover of the CSK30P (without taking the gear out) : both covers are clipped into each other and you can remove the one facing you by carefully using a screwdriver as a lever.
I did that to regrease it as it was slipping too, and had no issues since.

Thanks for the sheldonbrown article!

Things I've tried so far (none of which helped):
-lubed sprag clutch bearing with Kroil penetrating oil
- Checked for play in the BB axle bearings (none that was excessive)
-tighten pedals
-adjust rear derailleur (many times)
-lubed chain
-checked seating of rear wheel axle in dropout.

Ok, I have to to examine gear. I'm just tinker too

Hi. Has anything changed in the currently available tsdz2 kits regarding software uploading? I last programmed osf 0.8 in 2020.

 

[Elinx]

... I last programmed osf 0.8 in 2020.

That is the Casainho version and is abandoned.
Mbrusa has adapted OSF for Tsdz2 and did some updates based on the Mspider BT version.
The way of flashing isn't changed.

It depends of the display you have, which of the 3 versions you must flash.
- Tsdz2 stock
- Bafang 860C
- KT LCD3

The topic for mbrusa's versions of OSF you find here
