3D printed brushless gimbal for GoPro

Posted by frederic reblewski on June 29, 2013 at 7:00pm

I am a member of a French yahoo group on 3D printing. Today a member posted a link to this nice brushless gimbal that he designed for the GoPro hero3 and posted on Thingiverse. he did not reference the controller he is using but he published the design files here.

If your motor is 160C you have bigger problems then the plastic melting..

@Thomas, I'm not sure that I agree. Although I have zero experience with gimbals I have a ton on brushless motors and after a flight they aren't too warm. Now granted this is with substantial airflow, I don't think the plastic will cause too much problem. Also 3D printed plastic is fairly ridged and I think considering the fact that the parts used in the gimbal are rather small and short. I think it will be plenty strong. Anyway, I could be wrong on the heat thing.

Sorry for a gimbal newbie question but wouldn't it be better to put the gopro lens in line with the rollmotor axis?

They are rewound to increase the resistance over the phases, resulting in a very fine control. They are still three phase.

Do these things use standard 3-phase brushless motors or are they wound as single-phase LAT's (Limited Angle Torque motor)?
