And only around the cor or also between top/bottom of the motor and case

I cut one strip of 10 mm thick metrial (100 x 300 mm), found out that when you strech it and wrap around the stator, it behaves like a mixture of clay and rubber, so It shrinks back with a bit of delay, just enough to put the lid back in place (with some practice and few carefully chosen words).
So I believe it is not a bad solution, the thick material keeps a bit of pressure between the motor and the outer casing, improving the heat transfer (at least in theory :wink: ).
Unfortunately, the battery that I ordered 2 months ago is now stuck somewhere in the middle of the quarantine chaos, so I wasn't able to test it yet.
Oh well.
What's the thickness?silentguy said:Crafting copper
Nick2 said:Hi!
I put the thermometer probe in the cavity behind the plastic cover and added some thermo pad to keep the pressure agains the housing. Not directly on the stator, but better than nothing (I hope).

Also added one 10 mm thick thermo conducting pad to help cooling a bit.

I suggest you to replace you motor asap and be careful with your tests of temperature or you may repeat the same demagnetization/damage to the new motor.
Also the results of your tests may not reflect what happens to a good working motor that other users have.

What can cause demagnetized/damaged, can you provide more info?

You need to read about temperature sensor. You need to go in detail on the wiki pages.truongap said:casainho said:read the TSDZ2 FAQ: https://github.com/OpenSource-EBike-firmware/TSDZ2_wiki/wiki/FAQ
I don't see any references to demagnetization of motor.

imho finns are not always necessarycavi said:...
Probably not the cheapest way to go but a number of these and then also the silicone padding seem like would be a good solution
even this might work, .......
