Abstract

An electric brush motor for driving a fan of a cooling system comprises a rotor (fig 2, 30) and a commutator 36 on a shaft 32 mounted in a housing 50 that comprises an air inlet and an air outlet. A brush 66 and commutator 36 are arranged behind an armature 34 of the rotor in an air flow generated from the inlet to the outlet. The air outlet, brush and comutator can be in a front cover 52 of housing 50 which can comprise a rear cover (fig 2, 80). Brush 66 can be supported in a brush cage 64 that is directly mounted in a housing 50 having a bowl-shaped portion comprising a base 52 and a wall 54.The bowl-shaped housing can be made from a plastics or polymeric material and have metal sheets 42, shaped in half rings, at the housing lateral wall. A spacer 545 can keep an air gap between brush cage 64 and base 52. The lateral wall can have a brush cage support (fig 4, 547) comprising a groove to receive a protrusion (fig 5, 647) of the brush cage. Metal sheets 42 can be insulated from each other and connected to different potentials of the motor. Fan can have a hub (fig 6, 91) protecting the motor and cooling ribs (fig 6, 92) to generate the air flow in the motor.
