Publication number: 20150042203Abstract: An electric motor is provided including: a stator, an armature rotatably received within the stator and having an armature shaft on which a commutator is mounted, and a brush assembly. The brush assembly defines a first surface facing the stator and a second surface opposite the first surface. The brush assembly includes a brush card mount having openings, brushes in sliding contact with the commutator to supply electric current to the commutator, and thermally-conductive brush holders that house the brushes. Each of the brush holders includes a base portion disposed substantially along a same plane as a surface of the brush card mount to form the first surface of the brush assembly, and a main portion protruding from the base portion through a respective opening of the brush card mount to house a respective brush at least partially over the second surface of the brush assembly.Type: ApplicationFiled: August 7, 2014Publication date: February 12, 2015Applicant: Black & Decker Inc.Inventors: Stephen P.

Patent number: 8922092Abstract: A brush holder assembly including a quick disconnect assembly for quickly disconnecting a brush and electrical leads from a remaining component of the brush holder assembly to facilitate brush removal and replacement. The quick disconnect assembly includes a receptacle having a cavity for removably receiving and an end of the electrical lead, such as the nugget, and a resilient clip. When positioned in the cavity of the receptacle, the resilient clip urges a surface of the nugget into direct contact with a surface of the receptacle partially defining the cavity, completing an electrical current pathway from the brush through the electrical lead to the nugget, and from the surface of the nugget to the surface of the receptacle.Type: GrantFiled: March 7, 2011Date of Patent: December 30, 2014Assignee: Cutsforth, Inc.Inventor: Robert S.
