Hardware temperature control tsdz2

this is how I did to my tsdz2 using aluminum insert:

1. Buy a 1mx25mmx1m aluminum bar from Bunnings.
2. Cut to shape using paper template.
3. Appy thermal paste on both side.IMG_20231103_125144.jpg
4. install temporarily and remove, make sure the motor top surface touches the housing. I would say 1mm might not be thick enough, but 1.2mm is hard to be found, so I live with it. Better than the empty gap.

With summer here in Australia and high ambient temperatures I decided to do some of the heat dissipation mods in this thread. Ambient varying between 30-35 deg C. Motor would head reasonably quickly above 70 deg C stock.

I bought 1 x 80x40x2mm piece and 1 x 80x40x3mm piece of Gelid GP-Extreme thermal pads, and a 10g tube of GP-Extreme thermal paste. From https://gelidstore.com/
Also needed a length of 25mm x 1mm aluminium flat bar which was only a couple of dollars, and a reasonably chunky stainless steel hose clamp that would tighten to 65mm and that was probably 15mm wide, also a couple of dollars.

I followed the wiki guide for thermal compound inside the motor ends, and used about half the 2mm pad to fill the under motor gap. I used half the 3mm pad cut into 5 pieces to fill the gaps between the motor screws apart from the one closest to the controller. Roughly cut the flat bar to get two lengths that would wrap around the motor, and bent them around a tube of similar size. Installed them over the motor, with some thermal paste between the two layers. Slipped the pipe clamp over the top, also with some thermal compound between it and the aluminium. The screw mechanism of the clamp sits nicely between the motor and controller. Aligned it all so it sat low on the motor, and that gap between the almost full circle of the aluminium strips was over the single non-padded area of the stator and then tightened up the clamp. Stretched the rest of the 2mm thermal pad around the non controller side of the motor to fill in the gap to the outer case after checking the clearance. Used the rest of the 3mm pads as per the wiki on the top of the motor. The GP-extreme thermal paste is very thick, so had to use some cheap slippery thermal compound I had on hand to help slide the cover on. Tight fit but got it on.

Even with ambient temperatures in the low 30’s (C), after the mods haven’t been able to get the temp reading beyond 42 degrees. Super happy with the mods. All up around AUD$60. No special tools required. The aluminium flat bar will break if a sharp bend is bent back and forth.

Thanks to all in this thread for the great ideas!



Any pictures mate?
I bought the same flat 25mmx1m aluminum bar from Bunnings and made an insert to use between the top of motor and the housing:IMG_20231103_125144.jpg

But not sure what is the best way to wrap it around the motor body.

Thanks in advance.
 
Hi Everybody,
Noob here but I have learned a lot scanning/reading through this thread, thank you.
I’m hoping someone can recommend an online seller for decent quality and value thermal pads please? Bonus points if the seller is in Australia 🇦🇺.
Thanks 😊

All Australian sold TSDZ2s (ebay and etc), if I am not wrong, are new version with new controllers due to legal restrictions, not ST chips anymore. So there is no way to use OSF.
I bought an old version controller from China (old stock) and swapped it in. Now I am running OSF with VLCD5, which is so much more fun than before.
They told me that they still have 50 of those, but I am not very interested in this, unless a lot of people want them I might be able to help.

This is new information for me. Till now only a German webshop sold another controller version.
In that case you must have seen the difference between these controllers.
