Understand a dynamically braking system

  1. Hi,
    I finally found a way to brake dynamically a drill and i found it on a circular saw.
    I've drawn the electrical scheme of its brake which work with the drill(both the coils and the rotor are the universal motor).
    The problem is that I want to resize the componant to make it brake faster.
    But I don't fully understand of this brake work. So can anybody enlight me?
