    摘要: A labyrinth seal for a bypass discharge-type motor-fan unit includes a motor unit from which extends a rotating shaft that passes through an aperture in an end plate to drive a fan unit. Disposed within the aperture is a labyrinth seal configured to prevent liquid entrained in a working airflow from entering the motor unit. The rotating shaft also includes a vacuum bore, such that the negative pressure generated by the operation of the fan unit draws any liquid out of an evacuation zone maintained between the motor unit and the end plate. As such, the components of the motor unit are protected from being exposed to the liquid, thereby extending the operating life motor-fan unit.

    摘要: A curvilinear brush retainer and brushes for an electric motor assembly provides an end plate upon which is disposed a pair of curvilinear brush retainers. The brush retainers are configured to retain and support a pair of curvilinear brushes as they are biased against the commutator of the electric motor along a curvilinear path. Brush liners are disposed within the curvilinear path maintained by the brush retainers, serving to reduce the stiction or frictional force imparted to the brushes as they move, thereby reducing the temperature of the brush and extending their operating life.

    摘要: A fan end bracket for a motorized fan assembly has a plurality of curvilinear tapered air passages. Each air passage includes a flow port, such that air being moved by a rotating fan assembly is directed through the air passages and the flow ports. A skeletal motor assembly is affixed to one side of the end bracket such that the motor shaft is disposed through a shaft aperture in the end bracket. A rotating fan member is affixed to the motor shaft adjacent to the other side of the end bracket. A shroud member is provided to shroud the rotating fan member so as to cause the flow of air to be directed through the air passages. A baffle plate is interposed between the rotating fan member and the end bracket. The baffle plate includes a plurality of curvilinear scallops which correspond to the air passages in the end bracket. An effective flow port is created between the scallops of the baffle plate and the tapered ramp surfaces of the end brackets so the size of the effective flow port may be adjusted by merely changing the baffle plate so as to optimize the flow and pressure parameters of the fan for a particular motor size.
