Abstract
A DC brushless motor comprises a stator; a casing; a rotor and a cover. The magnet and the enhancing plate are locked by studs other than using glue agent. A block on the lower surface of the enhancing plate is embedded into a central hole of the magnet so as to support the magnet and cause that the rotary shaft will not con tact the magnet directly. A cover is extended with an inner sleeve. A groove seat is installed with a lower bearing and the inner sleeve is installed with a middle bearing and an upper bearing. The bearings are installed with respective enhancing pads. The rotary shaft of the rotor is installed with an annular enhancing flange and an annular inner flange which resist against the upper bearing. The inner flange resists against the enhancing pads of the middle bearing.
