Abstract
An engine cooling module includes a shroud structure 12. A housing 20 of a d.c. electric motor is formed integrally with the shroud structure 12. The housing has an open end 21. The motor has a drive shaft 26. A heat sink 22 is disposed opposite the open end and is insert molded with respect to the housing 20. The heat sink 22 defines a seat for a bearing 24 supporting the shaft 26. A flux ring assembly 48 is insert molded with respect to the housing. The flux ring assembly includes permanent magnets 33. An armature assembly 28 is disposed in the housing and fixed to the shaft for rotation in response to a magnetic field generated by the magnets 33. A commutator 32 is disposed in the housing and electrically connected with the armature assembly 28 and mounted for movement with the armature assembly. A brush card assembly 36 is coupled to the open end 21 of the housing to define an end cap covering the open end. The brush card assembly 36 has brushes 42 associated with the commutator 32. A fan 16 is coupled to the shaft 26 for rotation therewith.
