Abstract
A cooling module 10 of short axial length includes a fan 18 having a plurality of blades 16. A shroud structure 12 is spaced from and generally adjacent to the blades 16. A brushless electric motor 22 rotates the blades 16. The motor 22 includes a heat sink structure 24 coupled to the shroud structure 12 and defines a base of the motor 22. A shaft 32 is fixed to the heat sink structure 24. A rotor 34 is mounted for rotation with respect to the shaft 32. The fan 18 is coupled to the rotor 34. Magnets 48 are fixed in relation to the rotor 34. A lamination core 56 is fixed to the heat sink structure 24. A winding is wound about the lamination core 56 and is operatively associated with the magnets 48.
