Economical module for engine cooling applications

摘要

A cooling module includes a shroud ( 38 ) having an integral cover ( 42 ). The cover receives 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.
