Provided is a driving device for a full automatic washing machine in which a clutch unit can stop rotation of a dehydration axis without having a particular brake unit, since the clutch unit is closely adhered to a first dehydration axis and a bushing when the rotation of the dehydration axis is controlled according to a wash or dehydration stroke in a full automatic washing machine. In addition, since a clutch coupler of the clutch unit moves at a wash or dehydration stroke in a driving device of a washing machine to thus be attached to and detached from a clutch gear which controls rotation of the first dehydration axis, and to thereby control a rotational force which is transferred to an inner tub, the washing machine is embodied to have a simple clutch coupling structure. Further, a double-rotor and a single-stator of a brushless direct-current (BLDC) motor which is applied to a driving device of a washing machine are insert-molded into a waterproof structure, to thus maximize a contact area of a bulk molding compound (BMC) molding material to thereby maximize durability.

Stator for BLDC motor and BLDC motor having the stator, power transmission device for washing machine, driving device for washing machine and full automatic washing machine using the same

Provided are a stator for a brushless direct-current (BLDC) motor, a BLDC motor having a double-rotor/single-stator structure, and a vehicle cooler using the same, which uses a printed circuit board for an assembly that automatically sets an assembly position of stator core assemblies, to thereby secure waterproof, light-weight, and high power features. The stator includes a holder, a boss which has built-in bearings in order to support a rotational axis, and which enables the rotational axis to be rotated, a number of stator core assemblies which respectively enclose bobbins having inner and outer flanges at the inner and outer sides of a number of division type stator cores and in which coils are wound around the bobbins, and a printed circuit board for an assembly in which each stator core assembly is automatically position-set and then assembled and both end portions of the coil are mutually connected by each phase of U, V and W. After each stator core assembly has been temporarily assembled on the assembly PCB, the stator core assembly is insert molded using thermosetting resin to thereby integrally form the holder and the boss in the stator.

Provided are a radial core type brushless direct-current (BLDC) motor and a method of making the same, having an excellent assembly capability of division type stator cores in a double rotor structure BLDC motor. The BLDC motor includes a rotational shaft, an integrated double rotor including an inner rotor and an outer rotor, and a rotor supporter wherein a trench type space is formed between the inner rotor and the outer rotor, and an end extended from the inner rotor is connected with the outer circumferential surface of a bushing combined with the rotational shaft, and an integrated stator wherein one end of the stator is disposed in the trench type space and an extension axially extended from the other end of the integrated stator is fixed to the housing of the apparatus. In the integrated stator, U, V, W phase coil assemblies are formed of a number of core groups including a number of division type cores, wherein for each phase coil assembly, the division type core groups of the U, V, W phase coil assemblies are alternately disposed in an annular form in sequence of the phases, and the respective division type core groups are integrally formed into a single body in annular form by a stator support.
