Why worry ? just set the MOSFET temperature start and limit values and power will be gradually reduced from start to end limit tempeature. I would say 60C to 70C is pretty safe.
FZBob said:The Mystery 6384 has a fairly harsh and somewhat louder sound in comparison.
That's an interesting point because for me this motor had a more satisfying 'brushless' sound with a characteristic whirl and high pitched sound. Although at a specific RPM it resonates but it's not very problematic. When i turn by hand both motors the turnigy is indeed smoother but somehow in my application Mystery had a better sound and the transmission was smoother too. The shaft of the motor is 10mm thick which is a BIG plus because i have no longer have to support the end of the shaft - D5035 was bending like crazy at high loads causing all sorts of chain problems.
FZBob said:Overall I like this motor. I just wish it was a bit quieter & more pleasant sounding. However, for the price it's a bargain. I pay more for a tire!
Don't overpay for tyres. Buy Continental and Schwalbe tyres from www.bike24.com
Their top tyres are between 30E and 40E. I don't know if you have to pay import taxes, if any, because they are from Germany. For a speedy rear tyre i use Conti Race King 2.2 or if i want more grip and cushion than Schwalbe Rocket Ron 2.6. For front tyres with more grip i use Schwalbe Rocket Ron 2.2 - 2.8 or Conti CrossKing 2.4.
These tyres are lightweight and if you are agressive or ride in harsh environment chose the Protection(Conti) or SnakeSkin(Schwalbe) carcass or go with their more agressive pattern tyres which are more robust (Conti Mountain King, Schwalbe Knobby Nic, etc).
My VESC is set to:
Motor Current 75 Amp
Battery Current 40 Amp (I often see 44+ Amp peaks on the wattmeter after my ride...)
MOSFET temp cutoff start 85C (default)
MOSFET temp cutoff end 100C (default)
But remember, I only use high power for a few seconds... I ran a few tests when I had the metr working, and at high power the MOSFETS were getting up around 85C in under 30 seconds. I occasionally think about the big heavy duty VESC...
The sound thing is interesting. My motor mount is all aluminum, bolted to the frame. I wonder if the noise may be transmitted more, due to the solid mount. Is yours similar?
I do have a taste for Maxxis Minion DHF front tires...
