Default Brushless motor max temp

Hi all
What is the max temp that you should run brushless motors at.

Regards
Gary

depends on the manufacturer but the range I have seen is between 160-200F . Castle is the only one to my knowledge that recommends under 200. I think Novak likes to see no more than 170. Not sure about the others. Hope this helps.

Common thought is that Neo mags ore ok up to 200*F... may start to weaken at like 220+ range. Depends on who you ask.

Problem is you don't know exactly how hot the rotor is in there...

My rule of thumb is 180*... over that be careful and definitely try to keep it under 200*.

I had a Feigao come off the track at 300* the other day. Needless to say it's a paper weight now.

When I start to see 175-180 I try to take steps to cool it down.

Buddy took his truck off the track and motor was at 236. He was pulling it to runs something else (obviously) and we took it apart and the there were bits of solder that had slung itself inside of the front cover. opps

Castle techs told me in a phone call once not to go above about 180 because 1. the resins used to hold things together inside the motor start to brake down between 220-230deg. 2. What you temp on the outside of the can can be up to 50deg hotter in the core. Hence keeping it below 180 ensures you are running it cooler than those resins can melt and fail.

+1

Power begins to fall off at 160+ degrees.
For club racing I keep mine under 160.

Also, I just recharge my rotor.
