Abstract: An end cap assembly for an electric motor has a brush assembly, a circuit board, an inductor and a grounded metal element. The brush assembly has a plurality of brushes. The circuit board is fixed relative to the brush assembly. The inductor is electrically connected to the circuit board. The grounded metal element is positioned between the brushes and the inductor to absorb high frequency electromagnetic radiation transmitted from the brushes to the inductor.
