A braking grid cooling system may include a fan having a hub supporting a rotor and at least partially enclosing a stator, and a plurality of fan blades connected to and projecting radially from the hub; and a dynamic braking grid receiving the fan in a nested relation such that a combined height of the grid and the fan is less than a sum of a height of the grid and a height of the fan.
