Abstract: A brush holder assembly for an electrical motor includes a brush box including a main body and a cover portion, the main body with a cavity and including a set of first arms extending in opposition from the main body. The cover portion includes a set of second arms extending in opposition from the cover portion, and a set of projections extending in opposition to one another from the cover portion. Each of the set of first arms and a respective one of the set of second arms define a channel therebetween sized to receive a portion of a sleeve of the electric motor. The assembly also includes a cover that is coupled to the cover portion of the brush box, a brush located in the cavity of the brush box, and a spring positioned against the brush to force the brush towards a commutator of the electric motor.

Abstract: An electrical motor includes a sleeve, a rotational assembly located in the sleeve, and a shaft rotatably mounted about an axis extending longitudinally through the sleeve. The motor also includes an endcap, and a brake mechanism located about the axis of the shaft, the brake mechanism including a spring and a first bushing, wherein the spring forces the first bushing against the endcap to create a static frictional torque between the first bushing and the endcap when the motor is in an off state.
