Abstract
An electric brushless DC motor is provided including a rotor assembly having a substantially-cylindrical metallic rotor body and at least one rotor magnet mounted on a surface of the rotor body, a stator assembly rotatably disposed relative to the rotor assembly, and a molded structure formed in contact with the rotor body. The molded structure includes a first mold portion in engagement with the rotor body that integrally forms a fan at or adjacent an axial end of the rotor body, and a second mold portion extending integrally from the first mold portion at least partially in engagement with an inner surface of the rotor body. The second mold portion engages two axial ends of the at least one magnet to axially support and retain the at least one magnet relative to the rotor body.
