New "TSDZ2 Torque Sensor Central Motor"

[endlessolli]

In the last year or so I've done seven TSDZ2 builds. Three of those motors have failed already, possibly from heat-related damage to the controllers. The Electrify Bike website now has a notice up that says "NOTE: EBC has been experiencing reliability issues with TSDZ2B and OSF so we have temporarily stopped selling it until the issues are resolved." Has anyone else noticed a systemic problem with the TSDZ2? And if so is a fix from Tongsheng on the way?

I have meanwhile 8 systems installed (7 nonB, one B) using the exxellent latest version of @mbrusa firmware. All run fine without brakesensor and since several 100‘s to several 1000‘s of km. Only issue so far was one disintegrated coil from the torque sensor, which was a mechanical problem not related to the f/w

Hi Guys. I have a standard display with a flashed motor for 52v only. No other features.

After 4000 miles, the power delivery has failed. I set out with a fully charged battery and two miles out, power faltered.

The indicated power levels can be adjusted. Battery shows full. I tried a different display to no avail. The correct speed is indicated. Walk mode works ok. Occasionally, after trying walk mode, the pedals do get assist for a few revolutions.

Anybody have any suggestions? Much appreciated.

I'm wondering if it's the torque sensor. Do both parts need changing?

Do you do much stop and start riding or seldom need to come to a full stop? I do a lot of stop and starts and have had many instances when braking and the bike hasn't come to a full stop with pedals still weighted, motor is still running fighting the brakes (I can see the motor watts on display). The only way to avoid that (if the timing of where my feet is on the pedals is not right) is take both feet off the pedals, apply brakes and jump off the seat before the bike comes to a full stop. I've recently added a brake sensor and do not have this problem anymore.

I do ‚std‘ riding with start & stop every few km‘s. I had the ‚delayed support stop‘ onky happening with the original f/w, never with embrusas.

By original firmware, do you mean factory firmware, not OSF? I never ran factory firmware. I am running latest OSF for KT LCD3 & motor.

When did you buy your seven TSDZ2 kits? They don't seem to be available anywhere currently and has been that way for the last 6 months or more. It's not even on Tongsheng's website Mid Motor_Products_Suzhou Tongsheng Electric Appliances Co., Ltd. Motor Meter Controller , only the TSDZ2B, which is suppose to fix all the issues with the TSDZ2. Apparently they have not succeeded at least per EBC.

What happened to your TSDZ2's that failed? What kind of riding and what environment were they used in? Do you have brake cutoff sensors? I rode w/o brake sensors for 300 miles before installing them. W/o brake sensors, I've experienced instances while coming to a stop, with brakes engaged, my right foot's weight was on drive side pedal at 2 o'clock, approaching to 6 o'clock when I take my foot off pedal to dismount. Between 2 and 6 o'clock, the motor was still being powered, fighting the brakes. That can't be good for the plastic gears and motor. Since I installed the brake cut sensors, I do not experience that anymore.

I bought two TSDZ2's from Electrify about two years ago and five TSDZ2B's from Flycutycat about six months ago. All came with OSF. One of the TSDZ2s and two of the TSDZ2Bs have failed, all in the same way: when I turn on the motor the software seems to be going through some startup routine and then stalls out and says "waiting" and never finishes the startup process. My guess is that something failed on the controller so that whatever tests are running during startup never finish.

Hi what's up guys, I've got a little problem with my TSDZB2 and Pswpower is useless

Here's a vid.
https://youtube.com/shorts/PxelrNj83ko

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

Sometimes by pedaling backwards and searching for the right spot I can get them to 'connect', and then, things operate normally (although they will occasionally slip again if I put too much pressure)

The only way I can bike normally is by finding the right spot, and constantly keeping forward pressure on the pedals. If I backpedal a slight bit they will enter slippery mode again.

Does anyone know which component I need to order?

thanks a lot.

It's probably the CSK30P sprag clutch that needs to be replaced.

In TSDZ2B is different clutch not anymore CSK30P

 

[Kovko]

V TSDZ2B je iná spojka už nie CSK30P

Treba premazať olejom 40w5.

Thanks mate

edit: I realize it's this one, cant get the sprag clutch without the rest, but it is what it is

BTW here is my communication effort with PSWpower. I will never endorse these scammers again. First of all they dont even watch the video, secondly they put 0 effort towards helping me, hiding behind warranty.

Hi, I have a problem with the TSDZ2B, and am wondering which part I need to replace.

• Pedals slipping, no resistance, motor does not engage
• no noise

Please see this video:

https://youtube.com/shorts/PxelrNj83ko

Thank you.

hello
Does 6km/h model work normal. if yes, you should replace the torque sensor，if no, you should replace the controller

How the hell can the sensor be the problem if the cranks are slipping?

Then I asked them to watch again, as it is obviously a mechanical fault, and if I need the "big gear":

hello
yes
It is used for TSDZ2B

No shit it's used for TSDZ2B. I can tell that from the picture.

Can you please pay some attention to what I ask?
I paid good money for this motor last year.

If you can't help me, please give me contact info for someone else who can help me with the following question:

The reply:

we are not sure
You can open the motor to check the fault, our factory only provides one year warranty

I'm just sat here laughing, like what kind of reply is this.
0 effort
They sell replacement parts but dont want me to buy one I guess

Maybe I wont, I will just leave 1 star reviews for these idiots all over the internet and advise everyone never to buy their junk


edit: after some threats about reporting their business for selling illegal items in EU I got an answer. If you want something from these chinese I guess you have to threaten them

 

[twiersum]

My tsdz2 with osf & 850c display stopped working & says it can't communicate. Is this a known issue? I did replace the battery with a larger battery 54v I think, would too high of voltage cause a problem?

 

[Hillhater]

Is there an easy way to identify a “TSDz2B” from the original TSDZ2 ..?
anything external physical difference ?
or any clues in the sticker model or serial numbers ?..
Which one might this be ?

At first glance you see the difference of the housing

Does anyone know if there are plans for open source for the TDDZ8? It is a great motor, but OSF would be wonderful. It is more powerful than my TSDZ2B, but it really needs that boost feature on starting.

No, the controller hardware is complete different so porting isn't possible. It must be build from scratch.
imho mounting another controller, like Vesc is an easier and faster solution.

Hi, I managed to break/damage the motor in my TSDZ2B(OSF, 600w, cooling mod) while climbing up a very steep hill with a loaded trailer. Pedaling manually was working fine but the assist was gone. The rotor of the motor was stuck for some reason and the rest of the unit was totally fine, I could move the chainring without resistance by just touching the white gear. The motor now works again after disassembling the two metal end parts held by the 6 long screws(good excuse to renew the thermal grease too) and putting it back together, no apparent/visual damage.

The only issue is that the motor now makes a high pitched noise(think of server fans if you've had the pleasure of being around them but not as loud) when running. It doesn't seem to be dependent on load as I was using the throttle to test the motor before it putting it back in and it was still making the same noise. The power output feels the same as before but the casing feels just a little warmer than before during the same ride. Any idea what the problem might be? Misaligned rotor? Damaged rotor bearings?

Are there any pictures or schematics available anywhere? From what I saw from the firmware update tutorial vids it uses an Infineon XMC1302 instead of an STM8 like the one on the TSDZ2B. Schematics would make things easier but it should also be possible to decompile the hex files(if anyone has them) and figure out the pins that way. Difficult but doable.

Just to update, I installed a new "big gear" and it works perfectly again

Overall I'm quite happy with the TSDZ2B. I never even ended up installing the OSF although I might do that to squeeze a little more power out of it.

I have the speed thing/odometer disconnected and have about 6000 kilometers on it (~90 km/week for 17 months). So far the only issue I've had is the sprag clutch.

 

[dameri]

I got the message "motor blocked" on the 860C display. The bearing on the TSDZ2B white gear had failed. I replaced the 6001RS bearing and the motor works again. I had driven the motor about 4800 km.

I had no problems with the previous version (TSDZ2) blue gear.

Hi, I have a question about controllers.
I’ve had two 36v TSDZ2 motors so far (the pre-B version) and I’m fine taking them to pieces… I’ve replaced the blue gear and bearings and whatnot.
I just bought a 36v TSDZ2B but it’s a locked one. Whatever I do in the VLCD5 display settings, it remains limited to 25kph.
I can get round it by setting wheel size to 14 instead of 27, but then my speedometer and odometer are halved.
So…
I have a spare 36v 15A controller, bought a few years ago and never used.
I also have a controller removed from a 36v 500w kit, and that one is 36v 18A.
Can I put either of those older controllers in the new TSDZ2B?
I know those old controllers can be unlocked, which would sort out my problem. But are they compatible with the B version? (I suspect they are.)
Thanks in advance for any advice.


A bit more info… My battery is ok up to 20 amps so hopefully that’s ok with an 18 amp controller.
I don’t want to do open source stuff. I use macs and know nothing about programming and all that. More a spanners and grease person.

In the last year or so I've done seven TSDZ2 builds. Three of those motors have failed already, possibly from heat-related damage to the controllers.

All of your builds must use the 860 display? I dd a TSDZ2 build in 2022 and a TSDZ2B in 2023. both with OSF and VLDC5's. Probably close to 1500 miles on both bikes. I bought the extra axle bearings, but they are still sitting on my desk. I set the TSDZ2B with OSF cadence mode for my wife. For her, it's great. She thinks the 12A TSDZ2B is more powerful than her other 20A hub motor bikes.

Have broken a VLDC5 on my bike. I held the reset button down thinking it was the trip meter, but it was the odometer. It actually changed, and then the VLDC5 no longer completed the embrusa powerup procedure. It was hung up. but the bike still had throttle and one assist, I tried a display reset , and that did something, but there was still no OSF data numbers on powerup, and now thw motor was dead.

Based on the above, it seems possible that the user can accidentally affect the VLDC5 display, and that this may disrupt some software handshakes for the OSF/embrusa firmware. May apply to the 860 too,

I tried the cadence mode on my Raleigh M80 TSDZ2 w OSF a few days ago and it requires almost no effort on my part. Just move my feet and the bike takes off. Lol
