Abstract
An electromagnetic compatibility (EMC) shielding printed circuit board (PCB) has at least a routing layer and a ground layer. The shielding PCB has an opening that receives a motor bushing and at least one opening that receives motor terminals.
Claims18
An electromagnetic compatibility (EMC) component mounting device comprising:
- a shielding printed circuit board (PCB) having at least a first routing layer and a second grounding layer, wherein said first routing layer further comprises a plurality of EMC component mounts, the shielding printed circuit board further comprising one of an outer crimpable circumference plated with an electrical conductor such that said grounding layer is electrically connected to a motor housing when said shielding PCB is installed and a plurality of electrically conductive connection pads disposed on said routing layer, and said pads are operable to electrically connect the grounding layer to a motor housing when said shielding PCB is installed;
- a bushing opening defined by the shielding PCB that is operable to receive a motor bushing;
- and
- at least one terminal opening defined by the shielding PCB that is operable to receive motor connection terminals.

An electric motor comprising:
- a metal housing;
- a bushing extending from said metal housing;
- a shielding printed circuit board (PCB) having a first routing layer and a second grounding layer;
- said shielding PCB further comprising a bushing opening extending through said first routing layer and said second grounding layer and one of an outer crimpable circumference plated with an electrical conductor such that said grounding layer is electrically connected to a motor housing when said shielding PCB is installed and a plurality of electrically conductive connection pads disposed on said routing layer, and said pads are operable to electrically connect the grounding layer to a motor housing when said shielding PCB is installed;
- at least one terminal opening extending through said first routing layer and said second grounding layer, and a plurality of electromagnetic compatibility (EMC) devices mounted to said routing layer;
- wherein said bushing is received in said bushing opening, and at least one motor terminal is received in said at least one terminal opening;
- and
- wherein each of said EMC devices is electrically connected to at least one motor terminal.
