Abstract
A cooling module includes a shroud (38) having an integral cover (42). The cover receives a bearing structure (40). A fan (36) is provided for moving air. A rotor and stator assembly (30) has an opened end and includes a stator (29) having permanent magnets. A rotor (31) includes a lamination stack (16), windings (21), a commutator (20); and a shaft (18). The rotor is associated with the stator so as to rotate with respect thereto. One end (34) of the shaft is coupled with the fan and another end (39) of the shaft is received by the bearing structure. A brush and connector unit (52) is associated with the cover of the shroud and includes brushes (58) associated with the commutator, and an electrical connector (62). The cover covers the opened end of the rotor and stator assembly and covers at least a portion of a brush and connector unit.
