I noticed that BLDC Tool has a setting for motor temperature limits. However, I don’t know how to actually wire a temp sensor to the vesc. Is this doable? I haven’t seen anyone on here talking about temp sensors on their motors…
Also, if it is possible, which sensors do I use? I was thinking about a cheap probe sensor like this one.
I don’t think motor temp is an issue normally.
If your motors are running too hot, it’s likely because of the setup. Too high KV or too high gearing
I’ve checked my motors after climbing a fairly steep hill and they barely got warm.
10s, 190kv, 15/36 gears and 83mm wheels
That does sound like a lot of work… I will be prototyping some new designs, and I really need some sort of temperature monitor. I was hoping that the VESC could do it, because I would like to see a temperature graph over time compared to a graph of output amperage, and the VESC has some nice graphs on the Realtime Data tab.
I wouldn’t be against soldering to the VESC and programming, but I would need some assistance from someone on the forum who know a bit more than me. If that ends up being too much work, are there any other solutions that will give me what I’m looking for?
I implemented the motor Temps sensor check once for Duffman in the firmware but the tests were not successful. If anybody has a temp sensor wired in the same configuration as the PCB temp sensor (same resistors) then I am happy to help with the software. It’s not hard to implement temp cutoffs in that case. But I don’t have temp sensors installed. Another cool feature would be to add another temp sensor to the slave vesc which checks the battery temperature. But no cutoff is needed there because these Temps will never be a issue as long as the battery isn’t undersised for the system. So it only would be for interest.
OH and the motor Temperatur isn’t added to the actual 2.18 firmware. It’s only avaliable in the bldc-tool but does nothing in the firmware.
How is it going with temp-sensor “inplementations”.
2.18 is still the actual Firmware,…
So will the VESC 4 Firmware actually be further developed, probably not cause of the VESC6.
So it would be up to some of you coding-freaks out there to finish this work, ahh ? ,-)
