Abstract
A motor is provided which is configured to have at least a portion thereof received in an interior of a cover to reduce noise of the motor. The interior is defined by an inner peripheral surface of the cover. The motor includes a generally cylindrical housing having a closed end and an opened end disposed opposite the closed end. A brush card assembly is provided and includes a brush card and a cover support structure coupled with the brush card. The brush card and cover support structure close the opened end of the housing. The cover support structure has a plurality of resilient members extending from the opened end towards the closed end of the housing, with each resilient member being generally adjacent to an outer surface of the housing and being biased away from the outer surface of the housing. The resilient members are constructed and arranged such that when at least a portion of the motor is placed in the interior of a cover, the resilient members engage the inner peripheral surface of the cover to dampen vibration of the motor.
