An engine cooling module includes a shroud structure 12 having a shroud hub 46 constructed and arranged to receive a portion of a motor 16. A DC electric motor 16 has first and second ends and a rotatable shaft 40. The second end of the motor is received by the shroud hub. A fan 70 is provided that has a fan hub 72. The fan is coupled with the shaft for rotation therewith. The shroud hub 46 defines a protective cover covering the second end of the motor, and the fan hub 70 defines a protective cover covering the first end of the motor. Thus, no motor housing is required.

What is claimed is: 1. An engine cooling module comprising: a shroud structure having a shroud hub constructed and arranged to receive a portion of a motor, a DC electric motor absent a motor case, the motor having first and second ends, a rotatable shaft, and a flux ring separate from the shroud hub and defining the second end of the motor being received by the shroud hub, and a fan having a fan hub, the fan being coupled with the shaft for rotation therewith, the shroud hub defining a protective cover covering the second end of the motor, and the fan hub defining a protective cover covering the first end of the motor. 2. The module of claim 1, wherein: the flux ring has first and second ends and inner surface defining an interior and an outer surface defining an exterior, the second end of the flux ring being received in the shroud hub with the outer surface being directly adjacent to an interior surface of the shroud hub, the motor further comprising: permanent magnets coupled to inner surface of the flux ring, an armature assembly received in the interior of the flux ring generally adjacent to the magnets, the armature assembly including a commutator, windings and a shaft, a bracket mounted to the flux ring, and a brush card assembly mounted to the bracket, the brush card assembly having brushes associated with the commutator. 3. The module of claim 2, wherein the first end of the flux ring includes tabs and the bracket includes surfaces defining openings therein, the tabs being received in the openings thereby mounting the bracket to the flux ring. 4. The module of claim 2, wherein the second end of the flux ring includes notches therein and the shroud hub includes posts associated therewith, the posts being received in the notches to position the motor with respect to the shroud hub. 5. The module of claim 2, wherein the shroud structure includes a plurality of mounting tabs extending from the shroud hub, at least two fasteners being associated with the bracket, the fasteners being coupled with certain of the mounting tabs to mount the bracket to the shroud structure. 6. The module of claim 5, wherein the shroud hub has an annular wall with eight generally equally spaced mounting tabs extending from the annular wall, the at least two fasteners associated with the bracket being disposed generally 180 degrees apart and the certain mounting tabs being a pair of mounting tabs disposed generally 180 degrees apart. 7. The module of claim 2, wherein the bracket includes a bearing pocket receiving a bearing associated with an end of the shaft. 8. The module of claim 7, wherein the shroud hub includes a bearing seat receiving a bearing associated with another end of the shaft. 9. The module of claim 2, wherein the shroud structure includes mounting arms extending from an outer ring to the shroud hub, and wherein chokes are associated with the brushes, the chokes having legs with certain legs being electrically connected with power leads. 10. The module of claim 9, wherein at least one mounting arm includes a channel therein, the certain legs of the chokes extending to the at least one mounting arm, the module further comprising wires electrically connected with the certain legs of the chokes, the wires being disposed in the channel, the power leads being associated with a connector mounted to the shroud structure, ends of the wires being electrically connected with the power leads. 11. The module of claim 9, wherein the certain legs are directly connected with the power leads generally adjacent to the bracket. 12. The module of claim 1, wherein the shroud hub includes surfaces defining vent holes there-through.
