Guys, I'm working on a short article for the cooling of the TSDZ2... I tried all sorts of things... At the end to keep it simple, let me tell you what I found to be best.
Thermal Pads, GP extreme are best, and have high thermal transfer, but you can get something cheaper, just doesn't work as good.
Things to consider'
- one end of the motor, that faces the controller doesn't really need anything, so don't waste $$ on expensive thermal pad there IMO... Plus I wouldn't want to bring the heat closer to the controller, where the tops of the caps are..
- in the motor cover, there is a lip it fits into, so don't bring up the thermal pads too high or you won't be able to get the cover on
- the top of the motor is concave
- you don't want the thermal pads to catch and tear on the lip of the motor cover
So, here is what I do.
Motor:
- put 3mm thick pad around the middle, which is more recessed then the top and bottom cap
- then wrap the whole thing with another 3mm pad. Leave a little room at the top, because there is a lip on the motor cover.
- use 5-10mm kapton tape around the top edge, securing and protecting the thermal pad from catching/abrasion when the motor cover goes on.
Motor Cover:
- put a 5mm pad/strip around edge of recessed circle
- put a 2mm pad/strip in the middle of the 5mm pad/strip
- grease sides of motor cover with thermal grease, for easy slide on/off, and also aids in thermal transfer
Summary: 3mm around inside of motor to level out the recessed part between the caps, then another 3mm around the whole thing. Put a 5mm ring in the recessed lip at the bottom of the motor cover, and a 2mm pad to fill the middle. Grease the sides with thermal grease. Good to go.
Measurements of strips with pictures coming soon. I already took them but need to format them smaller to post, and I'm on my phone.
I tried alot alot alot of stuff... This is simple, looks clean, and works.
How well does it work? Depends how much you send on quality thermal pads.... Spend almost $100 gets you top of the line GP extreme, and you can run full power alot as long as you keep cadence up as well.... For $20 you can get cheap pads with about 1/5 of the performance... Not worth it IMO, of you are looking for a real solution.
That being said, for under $100, you can take the motor to the next (power) level... More than worth it for me.
