Motor assembly having improved electromagnetic noise filtering and dissipation
First Claim
1. A motor assembly having improved electromagnetic noise filtering and dissipation for a vehicle, said assembly comprising:
- a motor having at least two terminals extending therefrom for connecting to a power source;
a carrier having an upper surface and a lower surface with an outer periphery defining apertures for receiving said terminals of said motor;
a first conductive region disposed on one of said upper and said lower surfaces and adjacent one of said apertures for electrically connecting to one of said terminals;
a second conductive region disposed on one of said upper and said lower surfaces and adjacent said other of said apertures for electrically connecting to said other of said terminals;
a grounding region extending about said carrier on one of said upper and said lower surfaces for grounding said carrier;
a first non-conductive region insulating said first and said second conductive regions from said grounding region;
a circuit extending across said first non-conductive region electrically connecting said first and said second conductive regions to said grounding region for filtering electromagnetic noise;
an electrical ground positioned adjacent to and electrically connected to said carrier; and
a biasing device urging said grounding region of said carrier into electrical connection with said electrical ground for dissipating electromagnetic noise generated by said motor to said electrical ground.

Abstract
The subject invention provides a motor assembly having improved electromagnetic noise or interference (EMI) filtering and dissipation and includes a motor having at least two terminals. A carrier having an upper and a lower surface with an outer periphery defines apertures for receiving the terminals. First and second conductive regions are disposed on one of the upper and the lower surfaces and adjacent the apertures for electrically connecting to the terminals. A grounding region is disposed on one of the upper and the lower surfaces for grounding the carrier to an electrical ground and insulated from the first and the second conductive regions by a first non-conductive region. A circuit extends electrically connects the first and the second conductive regions to the grounding region for filtering EMI. A biasing device urges the grounding region of the carrier into electrical connection with the electrical ground for dissipating EMI and receptacles electrically connect the first and the second conductive regions to the terminals without requiring the terminals to be soldered to the carrier.
