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.

A brush card assembly 30 is provided for a permanent magnet brush motor 50. The motor includes a link wound, high speed side commutator 46 and an associated high speed side armature winding 44, and a link wound low speed side commutator 54 and an associated low speed side armature winding 52. The brush card assembly includes a brush card 31 including a high speed side having a positive brush 32 and a negative brush 32′ constructed and arranged to be operatively associated with the high speed side commutator 46, and a low speed side opposite the high speed side. The low speed side has a positive brush 33 and a negative brush 33′ constructed and arranged to be operatively associated with the low speed side commutator 54. The brushes are constructed and arranged with respect to the commutators to provide at least two different operating speeds of the motor.

A one-piece ball bearing mounting member 16 is provided for mounting a ball bearing in a housing. The mounting member includes a ring member 18. Tolerance take-up structure 22 extends from the ring member 18 in one direction and is constructed and arranged to engage at least a portion of a periphery of a ball bearing. At least a portion of the tolerance take-up structure 22 is resilient so that when inserted into the housing the resilient portion contacts a wall of the housing to take-up tolerances between the periphery of the ball bearing and the wall of the housing. A retaining structure 34 extends from the ring member 18 in a direction opposite the one direction. The retaining structure 34 is constructed and arranged 1) to permit insertion of the ball bearing mounting member into the housing in an insertion direction, and 2) to prevent movement of the ball bearing mounting member from the housing in a direction opposite the insertion direction.
