Exhaust stator and fan for a power tool

A router comprising:

• a motor housing including first and second clamshell halves forming an air inlet and a stator forming an air outlet, said housing having a central axis therethrough;
• an electric motor having a rotary armature, an armature shaft and a stationary member fixed with respect to the housing;
• an axial fan fixed to the armature shaft and positioned between said rotary armature and said stator for drawing air across said armature and stationary member, said fan having a plurality of radially extending fan blades tilted with respect to said central axis for forcing air in a substantially helical path;
• and
• said stator having a plurality of radially extending stator blades oppositely tilted with respect to said fan blades and said central axis for receiving air moving in a helical path from said fan blades.

A router comprising:

• a generally cylindrical motor housing disposed along a central axis and having first and second ends and an internal cavity, the first end providing an air inlet and the second end providing an air outlet and a central shaft outlet, wherein said air outlet comprises a stator;
• an electric motor having a rotary armature, an armature shaft and a stationary member fixed with respect to the housing;
• an axial fan fixed to the armature shaft and positioned between said rotary armature and said stator for drawing air across said armature and stationary member, said fan having a plurality of radially extending fan blades tilted with respect to said central axis for forcing air in a substantially helical path;
• and
• said stator having a plurality of radially extending stator blades oppositely tilted with respect to said fan blades and said central axis for receiving air moving in a helical path from said fan blades;
• and wherein said armature shaft is adapted to support a router bit outside of said air outlet.
