This compact ESC was designed by ST for drones, with a strong forced convection. 

At zero-altitude, zero-speed, without propellers, thermal dissipation remains an issue. 

Problem solved ! (Joke) ^_^

I have absolutely no experience in implementing FOC algorithm. This is my very first project, about brushless motor controller. I will do my best to release and share something basic but usable soon.
