Abstract: A motor includes a base, a stator, a dynamic pressure bearing unit and a rotor. The base includes a shaft tube. The shaft tube includes a closed end and an open end. The stator is mounted around the shaft tube. The dynamic pressure bearing unit includes a bearing, a dynamic pressure assembly and a thrust plate. The bearing is received in the shaft tube. The dynamic pressure assembly and the thrust plate are disposed in a position relatively adjacent to the open end of the shaft tube and relatively distant from the closed end of the shaft tube. The dynamic pressure assembly is located between the bearing and the thrust plate. A lubricating fluid layer is disposed between the dynamic pressure assembly and the thrust plate. The rotor is connected to the thrust plate and is rotatably coupled with the bearing.

Abstract: A lamp includes a base, a cooling fan and a circuit board. The base has a coupling portion, with a LED member mounted on the base. The cooling fan has a frame coupled with the coupling portion of the base, wherein the frame receives a driving unit and a fan wheel coupling with the driving unit in a rotatable way and has a first fixing portion. The circuit board has a second fixing portion coupling with the first fixing portion of the frame, with the circuit board electrically connecting with the driving unit of the cooling fan.

Abstract: An advection-type fan includes a frame, an impeller and a cover plate. The frame has a bottom plate mounted with a shaft seat. The bottom plate has a lateral wall on a periphery thereof that surrounds the shaft seat. The lateral wall has an air-guiding portion, a partitioning portion and an air-separating portion. An air inlet is formed between the air-guiding portion and the partitioning portion, and an air outlet is formed between the air-guiding portion and the air-separating portion. The partitioning portion comprises a first end defining the air inlet and a second end extending towards the air outlet. The air-separating portion is arranged on the second end of the partitioning portion. The impeller is rotatably mounted on the shaft seat. The cover plate is disposed on a top of the lateral wall of the frame.

Abstract: The present invention relates to a fan frame structure, which is composed of a plastic seat and a metal circular casing. At least two opposing guard fences disposed in a radial manner and extended upwards from a top edge of said seat. A fitting rim for inserting the metal circular casing is provided between an inner surface of the guard fence and a top surface of the seat. A side column is extended from a top side of the guard fence to cover and support the metal circular casing. Accordingly, the use of costly metal material can be reduced to lower the production cost, and the decrease of strength and deformation of the fan frame structure due to high temperature can be prevented. Meanwhile, the frame wall thickness can be reduced to enlarge the fan blade, thereby increasing air flow, fan speed and heat dissipation performance of a cooling fan.
