Re: New "TSDZ2 Torque Sensor Central Motor"

my engine start to behave very strange, sometimes, like every 10th second or so, the engine work for a second even if I do not put force on the pedals, I just coasting and it behave like I put force... sometimes also when I park the bike and just move the wheel some centimeters it could start. scar...

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...

Re: TSDZ2 speed sensing or torque sensing issue?

Well, I'm pretty sure it's the torque sensor that got shredded. I was using the bike today (with throttle) and the unit started making a grinding noise, and the pedals completely froze. I'm guessing the torque sensor got shredded inside the motor (I remember seeing that in the super-long thread abou...

TSDZ2 speed sensing or torque sensing issue?

Hi guys, I've had a TSDZ2 (48V) installed on my wife's bike for over 6 months now, and so far I've had mixed results: 1 month after installing it, the torque sensor crapped out, so I had to send the motor back for diagnostic and repair. Took 1 month + but the motor was fixed and we've enjoyed the bi...

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

The original firmware runs the motor very silently compared to the 6 steps/square wave/block commutation I implemented. I saw the PWM signals and are SVM just like used on FOC but I think they are simple doing "FOC" using motor parameters!! The development is blocked because I don't know how to imp...

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

Guys, this is your motor running with our OpenSource firmware! I was using a throttle on that test. So, since the other last video, seems that what is missing right now is "connecting" the torque sensor signal to the motor "throttle" signal, right?? Not yet, first I need to be able to read motor cu...

Re: New "TSDZ2 Torque Sensor Central Motor"

Also, based on your comments, I gather you haven't much experience with the TSDZ2. You are right. I have only done about 20 TSDZ2 conversions. Whereas Bafang mid-drives are well over 100. :lol: :lol: But seriously: out of these 20, how many did you end up having "premature" trouble with (i.e., some...

Well, I installed the 48V 750W TSDZ2 (which I bought from http://recycles-ebike.com) with Throttle, light cables etc. Installation went fine on a Townie, and the bike ran very well for 60 miles. Sadly, yesterday, the torque sensor started not working well, and now the bike is nearly unusable, 2 week...

Re: New "TSDZ2 Torque Sensor Central Motor"

Have you guys had any experience with the new style speed sensor? I bought a 48V 750W TSDZ2 and it came with a new style of speed sensor that has a Y connection (to plug a rear light I believe). It does not have an adjustment for bringing the sensor close to the magnet. The best I could do (see ima...

Re: Battery mount brackets

I know this is a super old thread, but I was wondering if you found a good source the bracket you were looking for.
I'm having the same situation: would like to mount a battery pack on the seat post but there's nothing to mount it on.

Re: New "TSDZ2 Torque Sensor Central Motor"

I think you'll be fine, have both the 52v and 48v system installed on different bikes and the 48v has a much closer fit but also gives me more problems than the 52v where the distance between is something like yours, works great. Awesome thanks! I'll let you guys know how it goes. Can't wait to get...
