摘要： An electric brushless DC (BLDC) motor is provided including an outer rotor assembly having a substantially-cylindrical metallic rotor body having, rotor magnets mounted within an inner surface of the rotor body, and a molded structure formed within the rotor body. The molded structure includes a main body formed on an inner surface of the rotor body to securely cover and retain the rotor magnets on the inner surface of the rotor body, an axial fan formed at an end of the rotor body opposite the rotor magnets, and a sense magnet mount formed at approximately a radial center portion of the axial fan. Alternatively or additionally, the molded structure includes a radial member projecting inwardly from the main body towards a center of the outer rotor assembly, and a bearing support member having a substantially cylindrical shape in an axial direction of the outer rotor and supported by the at least one radial member.
