ABSTRACT:
A router includes a motor housing having first and second clam shell halves forming an air inlet and a stator forming an air outlet, the housing having a central axis therethrough. An electric motor having a rotary armature, an armature shaft and a stationary member is fixed with respect to the housing. An axial fan is fixed to the armature shaft and positioned between the rotary armature and the stator for drawing air across the armature and stationary member. The fan has a plurality of radially extending fan blades tilted with respect to the central axis for forcing air in a substantially helical path. The stator includes a plurality of radially extending stator blades oppositely tilted with respect to the fan blades and the central axis for receiving air moving in a helical path from the fan blades. The stator blades are configured to cause air to swirl in a predictable manner when leaving the housing.
