Abstract
Provided is a slim type stator that is used to make a BLDC (Brushless Direct-Current) motor having a stator of a division core structure and a double rotor for use in a drum-washing machine, a slim type motor having the same, and a direct drive apparatus for use in the drum-washing machine. The stator includes: an annular division stator core assembly that is assembled in an annular form by winding a three-phase coil on a number of bobbins that are molded on respective outer circumferences of a number of division cores to thus surround a middle portion of each bobbin wherein each bobbin includes first and second flanges formed at one side of the bobbin and the other side thereof, respectively, and a coupling protrusion and a coupling groove that are formed at both side ends of the first flange that is disposed inward, and wherein the coupling protrusion and the coupling groove are mutually coupled between adjoining division stator bobbins; and a stator holder that molds the division stator core assembly that is formed in an annular form by winding the coils on the bobbins by an insert molding that uses a thermosetting resin, excepting inner and outer side surfaces of each division core of the division stator core assembly.
