Good Evening everyone.
I'm blanking out here, both of my Sunnysky x2208 (1260) motors keep overheating. They're rated for 15 amps max and about 160 watts max, and should run WOT at around 50 degrees Celsius with various sane set ups. Here is the confusing part, my set up only pulls 13amps max at 9.9v, pulling about 135 or so watts, which is well within a safe margin of error in my opinion. My battery and esc are chillin, but the motor heats up to 135*F pretty quickly. Even at 70% throttle, or 10 amps, it still wants to run at about that temp. Only at around 50 watts does it maintain an acceptable temperature. Even at 68 watts it was trying to rise up into the 120s (F)
I pulled some timing out of it, but it just dropped max amps a small bit but it didn't do much. Both of the motors exhibit the same behavior on 2 different ESC's with the same prop and battery.
So im starting to wonder, is ~150*F normal for these small motors close to their limit?. Buddy RC notes that the coils and bearings should be good to 356*F (180*c) Seems kind of excessive to me, a street car wouldn't even take those temps, but is this just how they run? My set up should be safe at WOT for as long as I need it. Down propping isn't necessarily an option for me, but what do you guys think? Ever heard of this? Any suggestions? Should I send it anyway?
