Brushless motor assembly for a fastening tool

An electric brushless DC (BLDC) motor comprising:

• an outer rotor assembly having a substantially-cylindrical metallic rotor body, and a plurality of rotor magnets mounted within an inner surface of the rotor body;
• a molded structure formed within the rotor body on an inner surface of the rotor body, the molded structure extending axially outside the rotor body to form an axial fan at an end of the rotor body;
• and
• a stator assembly received inside the outer rotor assembly and mounted on a shaft.

• an outer rotor assembly having a substantially-cylindrical metallic rotor body, and a plurality of rotor magnets mounted within an inner surface of the rotor body;
• a molded structure including a main body formed within the rotor body formed on an inner surface of the rotor body and a radial member projecting inwardly from the main body towards a center of the outer rotor assembly, the radial member forming a sense magnet mount at an end of the rotor body;
• a stator assembly received inside the outer rotor assembly and mounted on a shaft;
• and
• a sense magnet supported by the sense magnet mount.
