US Patent:

6992414, Jan 31, 2006

Filed:

Apr 4, 2005

Appl. No.:

11/098051

Inventors:

Kenneth Scott Thomson - Flowery Branch GA, US
Robert F. Bent - Gainesville GA, US

Assignee:

Siemens VDO Automotive Corporation - Auburn Hills MI

International Classification:

H02K 5/22
H02K 5/24

US Classification:

310 71, 310239, 310 43

Abstract:

A permanent magnet DC motor having electromagnetic interference (EMI) suppression includes a metal motor housing and a brush card assembly. The brush card assembly includes brushes and leads constructed and arranged to be coupled with a source of power to power the motor. A brush card housing has a first portion housing the brushes and a second portion , integral with the first portion, and housing the leads. A printed circuit board is mounted with respect to the second portion of the housing and carries at least one electromagnetic interference (EMI) suppression component constructed and arranged to suppress EMI generated by the motor. The leads are electrically connected to the printed circuit board so that current can be provided through the printed circuit board to the brushes. A contact member is electrically connected between the printed circuit board and the metal motor housing so that the at least one EMI suppression component couples the brushes to the metal motor housing thereby causing the metal motor housing to become an AC ground and EMI shield.
