Brushless motor having an overmolded rotor

A power tool comprising:

• a housing;
• and
• an electric brushless DC (BLDC) motor disposed within the housing, the electric motor comprising:
• a stator assembly defining a longitudinal axis;
• a rotor assembly having a rotor body comprising metallic material and at least one rotor magnet;
• and
• a molded structure including a first mold member extending within the rotor body in contact with the at least one rotor magnet, a second mold member extending integrally from the first mold member beyond a first axial end of the rotor body to engage a first axial end surface of the at least one magnet, and a third mold member extending integrally from the first mold member beyond a second axial end of the rotor body to form a fan at or adjacent the second axial end of the rotor body, wherein the fan generates airflow through the BLDC motor with a rotation of the rotor body, and wherein the first and second axial ends of the rotor body are oriented along two planes that are normal to the longitudinal axis of the stator.
