Re: New "TSDZ2 Torque Sensor Central Motor"

Wouldn't it be easier to make and probably braze or solder on some straight typical looking cooling fins. Not sure if heat sinks can be bent with exactly the same radius. It's actually really pretty easy to bend them if you just do it little by little and check it against the casing until it is flu...

Re: New "TSDZ2 Torque Sensor Central Motor"

Did you have a chance to test 3mm pads? Did you order them from eBay? I received the 3mm pads, but haven't tested them at all as I have been very busy(in the process of moving currently). I am also generally satisfied with the cooling performance I'm getting at the moment with the pads I have in th...

Re: New "TSDZ2 Torque Sensor Central Motor"

On the topic of thermal pads. ......... Panasonic seems to have made a thermal pad with graphite fibers aligned vertically........... In the link you gave I saw that these pads have a conductivity of 13 W/m-K, but for a price The cheap silicon pads about 2 W/m-K, that is a lot of a difference, but ...

Re: New "TSDZ2 Torque Sensor Central Motor"

QuirkyOrk, What thermal pad thickness do you recommend? i saw they start at 0.5mm and go up by 0.5mm increments. Thanks I used these 2mm pads (The only reason I chose these was it shipped from the US and I am inpatient :D ) https://www.ebay.com/itm/Grey-GPU-CPU-Heatsink-Thermal-Conductive-Silicone-...

Re: New "TSDZ2 Torque Sensor Central Motor"

I'm in South FL so I need to do something with my TSDZ2. It's nice to know this simple mod works. I was planning something more elaborate, but if this gets the job done then why not. Thanks for posting your results. Thanks for the kind words. Yeah I tried to keep it as simple as possible. I wanted ...

Re: New "TSDZ2 Torque Sensor Central Motor"

,,,,,, TSDZ2's awful thermal management....... ............ two things... -I filled the air gap around the motor with a thermally conductive silicone pad so that it now has something to shed the heat to the outer casing other than a not very thermally conductive pocket of air. -I attached some alum...

Re: New "TSDZ2 Torque Sensor Central Motor"

Here in Boston we just had the hottest July on record, so I took it upon myself to do a thermal management mod for the TSDZ2. I was routinely having to dial back my assist usage to stay below 75C on my 23 mile (37km) round trip commute so I decided I would do something about the TSDZ2's awful therma...

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

Hello everyone, I just installed the opensource firmware for the first time on my TSDZ2 36V, but for some reason it is limiting the power to around 320-380w. No matter how hard I pedal I can't raise the assist above 380w. What am I doing wrong? Is this normal? It seems significantly less powerful t...
