Re: New "TSDZ2 Torque Sensor Central Motor"

The pinout of both the 6 pin and 8 pin cables can be found here: https://github.com/OpenSource-EBike-firmware/TSDZ2_wiki/wiki/Wire-KT-LCD3-to-TSDZ2 Ignore everything to do with the KT-LCD3 unless you get interested in the TSDZ2 FOS firmware project. (Highly recommended) :) Thanks! I suck at solder ...

Re: New "TSDZ2 Torque Sensor Central Motor"

Whilst upgrading to 52V I messed up and installed an 8-pin controller into my motor while only having a couple of 6-pin displays to go with it. Anybody know where to get an adapter cable to bridge? My google-fu failed me and since I already feel stupid I thought it would be more productive to ask he...

Re: New "TSDZ2 Torque Sensor Central Motor"

Personally i would have reduced the amps by about 1 if possible in addition to increasing the voltage.. just to keep to load as low as possible on the internal gears.. Let me ask you this though.. a big qualm i had with the Bafang bbs02 was that it put the pedal position out on one leg by 10mm.. is...

Re: New "TSDZ2 Torque Sensor Central Motor"

I should have been more specific, jumping in here severeal pages later. Earlier in the thread some of us discussed the low maximum cadence allowed with the TSDZ2. Human maximum power need much higher cadences than the motor can handle. In my case, this messed my knees up and also resulted in a broke...

Re: New "TSDZ2 Torque Sensor Central Motor"

Just a quick report on the cadence thing: I recently received a new motor on warranty, proceeded to modify it with a 36v motor combined with a 48v controller and it works like a charm. Max cadence is now just about perfect, unless you´re extremely fit and pushing it. I highly recommend this solution...

andy, this was my solution: Oh, I also solved the ridiculous q-factor by ordering these (took A LOT of googling, I feel proud to be able to forum elf help at last): https://www.mirandabikestore.com/cranks/27-delta-0-standard-cranks.html#/11-color-black/32-length-170mm/101-interface-interface_isis/10...

Re: New "TSDZ2 Torque Sensor Central Motor"

Speedy probably got it right I´m afraid. Mine broke that way. The pedal no longer connects to the chainring - or it sort of does in a spongy way. I haven´t opened it yet because Tongsheng didn´t give me the go ahead yet but I´ve put my tools on short alert. The motor itself seems fine, I´ve just pus...

Re: New "TSDZ2 Torque Sensor Central Motor"

elem, that sounds great! Speaking of noise, considering that my own motor gets loud at high rpms rather than when it works hard, does your motor sound like a jet plane over 100 rpm? Writing as a noob on the subject, is it really that complicated to simply swap the controller? Or will that mess every...

Re: New "TSDZ2 Torque Sensor Central Motor"

Another high cadence solution would be a 36V motor with a 48V enabled controller. I'm bad with electronics but I assume the 36V version must be wound differently than the 48, and thus should spin really fast if fed 48V while still using the same total wattage? I'd buy one for sure.

Re: New "TSDZ2 Torque Sensor Central Motor"

I won´t spam the thread with any specifics about my order, but some related things may be of interest to most: *If 48V equals 4000 rpm then 52 should spin 4333. Good torque tempo would up from about a measly 70 cadence to some 76. However, the engine sticker on the 52V version promises 4500 - good c...

Re: New "TSDZ2 Torque Sensor Central Motor"

On another note, my knees can´t take the forced slow cadence and OCD induced sport jock tempo combination no more. Probably going to transfer the 350 unit to my full suspension winter MTB. The cheap spring dampers goes kangaroo on my ass with a high cadence anyways. But I like the motor and I need i...

Re: New "TSDZ2 Torque Sensor Central Motor"

Long time since I posted here. I´ve now wasted half a lifetime reading through the whole thread from back then. Enlightenment never comes cheap, but seriously, this comes down to sheer nerdiness on my part. Having ridden some 1000 km with my 350W 48V TSDZ2 the torque sensor broke and is to be replac...

Re: New "TSDZ2 Torque Sensor Central Motor"

Browse backwards in this thread for pictures and how to. Reading through MPM´s posts on the internals we don´t get to see him open the bottom bracket section? Thing is, the motor itself makes no creaking noises, it´s when I push the pedals. Doesn´t matter if the enginge is turned off. So I have a n...

PhaenTa posted this picture. Looks like the gears could be replaced to tweak the reduction?

Re: New "TSDZ2 Torque Sensor Central Motor"

A replacement gear-reduction kit would be nice so that max torque comes in at about 90-100 rpm and not 80-90. As it stands I believe max torque sits at a sunday cyclist 70 rpm or so. That´s why I ordered a 48V version, hoping it would run higher rpms, but I think mine spins the same as the 36. I do...

Re: New "TSDZ2 Torque Sensor Central Motor"

Thanks for the crank arm tips! I googled up on them but it seems nobody´s interested in presenting pictures of them from the top side, so to speak. No way to tell how tight they go. Since I have a lot of clearence between my heel and the crank arm center I actually could get away with a negative q-f...

Re: New "TSDZ2 Torque Sensor Central Motor"

Oh, I forgot to mention one thing: the included crank arms together with the bulk on the drive side makes for an absoultely ridiculous q-factor, sqewed heavily to the right. I got some 4 cm to spare to my chainstay and that´s on a tourer with space for big tyres. Anybody who cares about their riding...

Re: New "TSDZ2 Torque Sensor Central Motor"

I ordered mine directly from Tongsheng, running @ 48V, 350W. I´m pleased with the quick response and general feel of it. Very reminiscent of the Bosch and Yamaha mid drives. Mounted on a stable high-end touring bike it´s speedy. The torque sensor is optimized for lazy cycling: if I push just a bit t...
