A motor includes a stator and a bus bar supported axially above the stator. The bus bar includes a concave portion arranged in a lower surface thereof facing toward coils of the stator. In a gap defined between the coil and the concave portion, a portion of the wire extracted from the coil and wound in the circumferential direction (i.e., a crossover wire portion) is accommodated. The bus bar includes a wire-positioning hole through which the wire is led to a terminal to be connected with the wire.

A coil unit for a motor stator includes a plurality of layout layers. At least one coil and a conductive portion electrically connected to the at least one coil are formed on a surface of each layout layer. The conductive portions of two adjacent layout layers are electrically connected to each other. An insulting layer is provided between two adjacent layout layers. The coil unit can be coupled to a face of a substrate to form a motor stator with reduced axial height and reduced volume.

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.

A combination structure of a motor has a base board, a printed circuit board and at least one sensing unit. The base board is used for placing a stator and a rotor and has at least one first assembly hole. The printed circuit board is connected to the base board and has at least one second assembly hole. The sensing unit is used for sensing a magnet of the rotor. The second assembly hole of the printed circuit board is placed corresponding to the first assembly hole of the base board for commonly containing the sensing unit so that an axial height of the motor is decreased.

A stator for a DC brushless motor includes an annular insulating ring integrally formed from an insulating material. The annular insulating ring includes an outer peripheral face and an inner peripheral face. A plurality of winding portions extends from at least one of the outer and inner peripheral faces. A coil unit is wound around each of the plurality of winding portions. The stator can be utilized in various DC brushless motors. Since the stator does not include conventional silicon steel plates and is comprised of an annular insulating ring and a coil unit, advantages including low manufacturing costs, assembling convenience, possible reduction in the axial height, and high rotational stability are obtained.

A cooling fan includes a fan frame, a circuit board, a stator-coil unit and an impeller. The fan frame includes a metal seat and a lateral wall. The metal seat comprises an engaging face and an engaging portion arranged on the engaging face. The lateral wall is arranged on a periphery of the metal seat and includes an air inlet and an air outlet. The circuit board includes a positioning hole. The circuit board is press fitted around the engaging portion of the metal seat via the positioning hole and adhered to the engaging face of the metal seat. The circuit board includes an insulation layer facing the metal seat. The stator-coil unit is mounted on the metal seat of the fan frame and electrically connected to the circuit board. The impeller is rotatably coupled with the stator-coil unit. Therefore, the Cooling fan and the assembly method thereof can simplify the assembling step and improve the assembling convenience, and can effectivley reduce the axial height of the cooling fan.

A fan has a housing with a wire-guiding slot. One of plural connecting members is taken as a line fixed portion having a linking end facing the wire-guiding slot, with the linking end connecting to a section of a peripheral wall of the housing and the section axially aligned with the wire-guiding slot of the housing. A base is coupled to the housing. A power line has one end connected with the connection port and the other end extended beyond the housing via the wire-guiding slot. An impeller is rotatably mounted inside of the housing. Therefore, the line fixed portion can be close to the wire-guiding slot. Thus, the power line can be extended straight through the wire-guiding slot. A distance between the connection port and the wire-guiding slot is shortened to enhance assembling convenience of the power line.

An advection fan includes a housing having a metal housing base and a closure member. A lateral wall is arranged between the metal housing base and the closure member and includes an air inlet and an air outlet. A horizontal air passage is defined between the metal housing base and the closure member. The metal housing base includes an engagement section. A stator includes a coil unit embedded in or abutting and attached to the engagement section of the metal housing base. The coil unit abuts the engagement face of the metal housing base. The coil unit includes a substrate and at least one coil formed on a surface of the substrate by a printing circuit or electroforming process. An impeller is rotatably coupled to the shaft tube of the stator. A gap is formed between the impeller and the coil unit of the stator.
