Abstract: A method for manufacturing a magnet-conductive device includes performing a punch process to a plate by a glue-injectable punch structure, wherein the glue-injectable punch structure includes a punch head and a control member. The punch head comprises an accommodating cavity, an injection hole and an inlet, and a supply channel is formed by the accommodating cavity, the injection hole and the inlet. The control member selectively obstructs the supply channel or permits the supply channel into conduction. By using the method for manufacturing the magnet-conductive device, the stack between plural plates is simplified, and the coupling strength between adjacent plates is enhanced. In addition, this invention considers the gel between adjacent plates to be insulating medium to lower the iron loss of the magnet-conductive plates.

Abstract: A rotor core assembly for a reluctance motor and a manufacturing method of the same, wherein the rotor core assembly has multiple silicon steel laminations and a nonmagnetic material. The silicon steel laminations are axially stacked, and each silicon steel lamination has multiple magnetic flux sections. Each magnetic flux section has multiple arcuate grooves and multiple salient poles. The arcuate grooves are concentrically arranged. The salient poles protrude into the grooves. The nonmagnetic material is disposed in the grooves, and is wrapped around the salient poles, which enables the silicon steel laminations to remain securely assembled together. The salient poles are disposed in the grooves to avoid ruining the magnetic line of force. As a result, the rotor core assembly can keep rigidity of the assembled silicon steel laminations, and can keep the integrity of the magnetic circuit.

Abstract: A method for manufacturing magnet-conductive device includes a filling step and an adhering step. The filling step includes providing a glue by a glue dispenser and contacting the glue with a first magnet-conductive plate to make the glue adhered to a lower surface of the first magnet-conductive plate. The adhering step includes making the lower surface of the first magnet-conductive plate face toward a second magnet-conductive plate, making the first magnet-conductive plate and the second magnet-conductive plate stackable from each other and adhering the first magnet-conductive plate and the second magnet-conductive plate via the glue. Eventually, by repeatedly performing the filling step and the adhering step, the desirable stacking quantity is achieved to form a magnet-conductive device.

Abstract: A motor structure includes a case, a rotor, a first magnet, a second magnet and at least one magnetic conductive plate, wherein the rotor is disposed within an accommodating slot of the case, and the first magnet is disposed between the case and the rotor. The first magnet comprises a first end portion spaced apart with the case to define a first separation space. The second magnet comprises a second end portion spaced apart with the case to define a second separation space. A spacing slot is composed of the first separation space and the second separation space, and the at least one magnetic conductive plate is disposed within the spacing slot. The magnetic conduction through the at least one magnetic conductive plate enables to lower the reluctance of the motor structure for prevention of magnetic flux leakage therefore increasing the air-gap flux density.

Abstract: A fan motor structure is provided. A fan is disposed within an accommodating hole at a center of a body. A permanent magnet and a printed circuit board (PCB) provided with plural coils are respectively disposed between an upper ring and a base of the body. An axial air gap is formed between the coils and the permanent magnet. A bearing is disposed between the upper ring and the base. The fan blades of the fan extend from the periphery of the accommodating hole toward the center of the fan. An axle center of the fan overlaps with that of the body. The coils after being supplied with a current create a flux linkage with the permanent magnet. Due to the flux linkage and the axial air gap between the coils and the permanent magnet, the upper ring is forced to rotate, thus driving the fan to rotate.
