Abstract

A power tool is provided including an electric motor and a tool housing arranged to house the motor. The electric motor includes a stator, an armature rotatably with respect to the stator and having an armature shaft, and a fan rotatably attached to the armature adjacent the stator. The fan includes blades each having an angled side edge such that a longitudinal length of each blade is smaller at an outer periphery of the fan than at an inner edge of the fan blade near the armature shaft. The tool housing includes an annular rib disposed around a periphery of the housing in close proximity to the fan. The annular rib has an angled surface substantially parallel to the angled side edges of the fan blades to redirect airflow generated by the fan in a centrifugal direction of the power tool.
