HKlll 4035-530 kv Normal operating Temperature Range
Does anyone have this info? I fly scale only. So if all perimeters are set correctly [pwm, timmimg, 12s] what would be a healthy operating temp range?
I am wondering if I need to replace bearings.

I found this info on the HKIII 4035-530:
The stators are made with 0.2mm laminations to give maximum efficiency, and minimum Eddy current losses. The stators are epoxy coated to prevent shorts, and are wound with wire that is rated at 180 degrees C (356 F). The magnets used in Scorpion Motors are N-50EH style, which are rated for operation at 200 degrees C (392 F), making a motor that is virtually impossible to burn up in normal use.
I wouldn't worry too much about the motor temp if you're going to be running lower headspeeds as you typically would in scale flight.

As for replacing the bearings, I'm thinking that may depend more on how many flights you have on the motor as opposed to the temperature (for his particular motor anyway).

Thanks. I see that now and remember reading it before but forgot. Comes with age.. Good... so the 160F I'm getting is nothing to worry about. Motor is very smooth so bearings are probably ok for now. Will keep an eye on them, it's a used motor but I've flown it a lot so far. Thanks again.Dennis
