mattr Posted April 25, 2014 Share Posted April 25, 2014 Run it from your receiver. Quote Link to comment Share on other sites More sharing options...
lilllad83 Posted April 25, 2014 Share Posted April 25, 2014 +1 either in the aux channel or with a 2 way splitter if no spare slots in your rx Quote Link to comment Share on other sites More sharing options...
norcoforever Posted April 26, 2014 Share Posted April 26, 2014 why do you require another fan? i would look at cause rather than masking any potential issues Quote Link to comment Share on other sites More sharing options...
Noj Posted April 26, 2014 Share Posted April 26, 2014 The velineon motor runs hot, especially on 3s. Quote Link to comment Share on other sites More sharing options...
mattr Posted April 26, 2014 Share Posted April 26, 2014 How hot is the motor actually getting? Hot enough to burn and blister skin is still somewhat below the limit for most decent brushless motors. Do you have an IR or contact temp probe, or are you just guessing? (Using a reported temperature on the ESC isn't much better than guessing!)

norcoforever Posted April 26, 2014 Share Posted April 26, 2014 Hot enough to burn and blister skin is still somewhat below the limit for most decent brushless motors. the accepted limited is around 60-70 degrees =/ you should be able to hold the motor for at least 4 or so seconds Quote Link to comment Share on other sites More sharing options...
mattr Posted April 28, 2014 Share Posted April 28, 2014 (edited) Accepted by who? Brushless motors will happily run at 80+ degrees almost indefinitely. (According to the manufacturers) Only issue comes with measuring the surface of a large motor, the core will be hotter.

mattr Posted April 28, 2014 Share Posted April 28, 2014 (edited) Oh, and FWIW, skin begins to burn at 60 degrees anyway! Edited April 28, 2014 by mattr Quote Link to comment Share on other sites More sharing options...

(According to the manufacturers) Only issue comes with measuring the surface of a large motor, the core will be hotter This is why we stop at 70c, The magnets have the potential to start failing at 80+ Oh, and FWIW, skin begins to burn at 60 degrees anyway! Skin doesn't burn at 60. Quote Link to comment Share on other sites More sharing options...
Tug Posted April 28, 2014 Share Posted April 28, 2014 If the surface of the motor is reaching 80, the rotor will be hotter and so some remedial work is needed to reduce that temperature. If my motors hit 70, I consider that too hot and make some changes. 1 Quote Link to comment Share on other sites More sharing options...
