Abstract
A cooling module 67 includes a motor assembly 42 having a motor case 24 having at least one open end and including mounting brackets 30 integral therewith. Each bracket has only a bottom portion 32 connected with the motor case. An armature assembly is disposed in the motor case and includes a rotatable shaft 46. A brush card assembly 56 is associated with the armature assembly, and an end cap 60 is disposed over the brush card assembly and partially covers the open end of the motor case and thereby defining a non end cap covered motor portion 63. A fan 64 is coupled to an end of the shaft and has a hub substantially covering one end of the motor assembly. A shroud 74 has a motor cover 76. Fastening structure 78 is associated with the shroud and engaged with the brackets thereby mounting the motor assembly to the shroud, with the motor cover substantially covering the end cap and the non end cap covered motor portion.
