First Claim
1. A motor filter assembly comprising:
- a motor housing, said motor housing including a motor housing conductive portion and an aperture, said conductive portion spaced away from said aperture;
a first motor brush mounted to said motor housing;
a second motor brush mounted to said motor housing;
a first filter, said first filter comprising a filter first conductive structure comprising a filter first external electrode and a filter first internal conductive structure, a filter second conductive structure comprising a filter second external electrode and a filter second internal conductive structure, and a filter shield structure comprising a filter shield external electrode and a filter shield internal conductive structure;
wherein said filter first external electrode is conductively connected to said first motor brush;
wherein said filter second external electrode is conductively connected to said second motor brush;
wherein said filter shield external electrode is conductively connected to said conductive portion of said motor housing; and
wherein said filter shield internal conductive structure shields said filter first internal conductive structure from said filter second internal conductive structure.

Abstract
The invention provides a structure and method of its use comprising a filtering and interference suppression device (62), particularly of the broad band type, for an electric motor (34) comprising at least a first powering brush (16) for an armature commutator of the electric motor (34), of the type comprising a capacitor (64), one terminal of which is electrically connected to a strip conductor (38) that electrically powers the first brush (16) powering the armature commutator of the electric motor (34), and the other terminal of which is electrically connected to a ground strip conductor (58), connected, in turn, to the electrical ground (60) of the electric motor (34), characterized in that the capacitor (72) of the filtering and interference suppression device (62) is of the non-inductive type, and in that each of the non-inductive capacitors (72) is directly attached to a circuit board (73) comprising strip conductors, of which are at least one powering strip conductor (38, 40) for a brush and one ground strip conductor (58).
