[Paparazzi-devel] Motor problems

[Nathan Sandoval]

Hi all,

I am currently working on a University paparazzi project at the University of Arizona and I am trying to just get a basic plane in the air. I have all the components I need and I have tested most of my components and they are working. However, I have a problem with my motor. Anytime I connect my speed controller to the TWOG and then power the TWOG and Speed controller (and of course the other end of the speed controller is connected to the motor), the TWOG begins to heat up rapidly. One of my TWOGs actually burned up from being powered on for about 30 seconds while connected to the speed controller. I  currently powering both the speed controller and the TWOG from the same battery. My speed controller is a 40-Amp Lite Pro SB Brushless ESC. (I am not terribly experienced, but I wonder if my motor is just too big/ drawing too much power?)

My idea to solve the problem is to power the speed controller and the twog separately, and maybe just have the transmit pin connected between the TWOG and speed controller to ensure that it doesn't try to draw power from the twog.

Would this work? (I ask because I don't want to blow up another TWOG!) Any other ideas for how to solve this overheating problem?

thanks!

Nathan
