A blower assembly' includes a housing&#x2032; having an inletand an outlet. The housing includes an inlet ring&#x2032; at the inlet. A blower wheel&#x2032; is mounted for rotation in the housing. An electric motorincludes a shafthaving an axis B. The shaft is coupled to the blower wheel so that rotation of the shaft causes rotation of the blower wheel that causes air to flow from the inlet to the outlet. The inlet ring has an annular extensionextending linearly in the same direction as the shaft axis B. An endof the blower wheel&#x2032; is within bounds of the extension

An electric motor includes an armature structurehaving a shaft, a lamination stackcoupled with the shaft, a commutatorcoupled with the shaft, and windingscarried by the lamination stack and connected to the commutator. Brushesengage the commutator to deliver electric current to the windings. The motor includes a frame structureand permanent magnetscarried by the frame structure. At least one assembly is provided including a sleeve bearing, an elastomer structurecoupled with the sleeve bearing, and a retainer. The sleeve bearing is operatively associated with an end of the shaft to support the shaft for rotation. The elastomer structure is clamped between the frame structure and the retainer, with the retainer being engaged with a portion of the frame structure to maintain clamping on the elastomer structure. The assembly is constructed and arranged to reduce transmission of noise from the sleeve bearing to the frame structure, and to control endplay of the armature structure by controlling compression of the elastomer structure due to clamping by the retainer.

An electric motor has a unitary frame. The frame includes locating structure extending from an end portion thereof. The motor includes a shaft and an armature disposed within at least a portion of the frame and constructed and arranged to rotate the shaft. A commulator is associated with the shaft. Windings are carried by the armature and connected to the commulator. Permanent magnet structure is carried by the frame and is disposed generally adjacent to the armature. At least one brush arm is coupled to an associated locating structure. A brush is coupled with an associated brush arm so that the brush engages the commutator to deliver electric current to the windings. A structure, containing iron, is disposed about at least a portion of the permanent magnet structure to define a flux path for the motor.

An air door assembly for a fan shroud assembly includes a door having an upper portion, a lower portion and a hinge portion located between the upper portion and the lower portion, a frame defining an opening in the fan shroud assembly, and a hinge defining a pivotal axis pivotally coupling the hinge portion of the door to the frame. The door is adapted to pivot relative to the frame about the pivotal axis between a fully closed position and a fully open position. The upper portion of the door and the lower portion of the door may be in a substantially horizontal orientation when the door is in a fully open position. The hinge may include a pair of pivot pins extending along the pivotal axis at least partially into the opening from opposite lateral sides of the frame and a corresponding pair of at least partial sleeves at opposite lateral sides of the hinge portion of the door, the pair of pivot pins being received within the pair of at least partial sleeves to couple the door to the frame. The pair of pivot pins may be adapted to snap-fit into the pair of at least partial sleeves. The air door may transition between the closed position and the open position at a first air velocity and between the open position and the closed position at a second air velocity, the first air velocity being greater than the second air velocity. In another preferred embodiment a fan shroud assembly includes a housing having a plurality of openings and at least one air door assembly located within the housing.

A high efficiency fan and stator arrangement for generating an airflow through a heat exchanger is disclosed herein. The fan is rotated about its rotational axis by an electric motor, and includes eight blades extending radially from a hub to a circular band. Each fan blade has a stagger angle and chord lengths which vary along the span of the blades. Each fan blade also includes a trailing edge having a flat surface extending along the edge. The flat surfaces of each fan blade are coincident with a plane perpendicular to the rotational axis. The fan produces an airflow when rotated about the rotational axis, wherein a component of the airflow occurs at a first angle to the rotational axis. The fan support has a central bearing support and twenty elongated airfoils extending radially outward from the bearing support. Each airfoil has substantially the same length as the fan blades and includes a curved airflow guiding surface having a leading edge and a trailing edge downstream from the leading edge. The curve of the guiding surface is a generally circular arc with a tangent to the guiding surface at the leading edge substantially at the first angle to the rotational axis, and a tangent to the trailing edge at a second angle to the rotational axis less than the first angle. The fan support is located downstream of the heat exchanger to guide the airflow produced by the fan through the heat exchanger.
