An outer rotor type motor includes a rotation shaft installed in a bearing housing; a stator formed of a field winding; a rotor disposed outside the stator to house the stator and having a yoke surface on which a permanent magnet for performing a magnetic interaction with the field winding of the stator, the rotor rotating around the stator; and a shaft bushing for connecting the rotor and the rotation shaft. The shaft bushing is insert-molded at a central portion of the rotor to be connected with the rotor.

An outer rotor type motor includes a rotor housing having a bottom portion and a sidewall upwardly extending from and an outer peripheral edge of the bottom portion, and a shaft bushing having a base and a hollow shaft-insertion portion provided at a center of the base. The base of the shaft bushing is coupled at the bottom portion of the rotor housing by an insert molding. A driving shaft is fitted in the shaft-insertion portion of the shaft bushing. A plurality of blade holes are circumferentially formed in the bottom portion of the rotor housing, and a plurality of blades are formed by an insert molding such that the blades are disposed at one edges of the respective blade holes in the bottom portion along a radial direction.

The present invention relates to a method of continuously producing a phosphor at a supercritical water (SCW) condition and an apparatus used in the method. A phosphor produced according to the method of the present invention has similar luminosity to a phosphor produced according to a conventional solid-state method and the size and shape of particles thereof is also uniform. Accordingly, a phosphor according to the method of the present invention is applicable in various fields such as plasma display (PDP) and field emission display (FED). Also, in the method of producing a phosphor according to the present invention, the total reaction time is within about one minute, which is shorter than in the solid-state method. Also, since a separate heat processing process is not needed to obtain crystallized particles, it is efficient in aspects of time and energy.

A rotor for use in an induction motor includes a main body installed to be rotatable by having a gap inside a stator, providing a flow path of magnetic fluxes produced from the coil, and including a plurality of conductors formed on an edge region of the main body; a pair of barriers formed to pass through the main body in a manner to have a semi-spherical shape from a sectional view, base lines of the semi-spherical shape being disposed to face each other; and a plurality of permanent magnets disposed inside the individual barriers. Therefore, the permanent magnets can be easily affixed to the inner side of the individual barriers, and the loss of the magnetic fluxes is minimized, thereby improving the efficiency of the rotor.
