Abstract: A motor includes a shaft, a shell, a sleeve, an abrasion-resistance piece, a bearing, an oil seal, and several compressed springs. The shaft has an axial line. The shell is connected to the shaft. The sleeve has an accommodating space, and the wall of the accommodating space forms a first inclined surface which is inclined at an angle with respect to the axial line. The abrasion-resistance piece is disposed at the bottom of the accommodating space. The bearing is disposed in the accommodating space, and the outer wall of the bearing forms a second inclined surface corresponding to the first inclined surface. The shaft passes through the bearing and abuts the abrasion-resistance piece. The oil seal is affixed to the wall of the accommodating space and covers the bearing. The compressed springs are connected between the oil seal and the bearing.

Abstract: A fan includes a fan impeller. The fan impeller includes an inner frame, an outer frame and a disturbing structure. The inner frame rotates along a rotation axis. The outer frame is disposed around the inner frame. The blades are disposed between the inner frame and the outer frame and arranged radially. The disturbing structure has a plurality of protrusion columns disposed on the outer frame, and the protrusion columns are arranged surrounding the blades. The protrusion columns are provided to generate vortexes in the flow field for disturbing the flow as to reduce noise, and the wind pressure can be increased to obtain better operating characteristics.

Abstract: A thin fan includes a frame and a driving device. The fan frame includes a base and a frame shell. The driving device includes a stator structure and a rotor structure disposed corresponding to the stator structure. The stator structure includes a stator pole group, a bushing, a bearing and a compression-resistant pillar. The rotor structure includes a hollow-cylindrical shaft, a rotor shell, a magnetic structure and an impeller. The shaft is mounted on the outer periphery of the compression-resistant pillar and is disposed between the compression-resistant pillar and the bearing. The rotor shell is connected to the shaft. The magnetic structure is disposed on the inner wall of the rotor shell, and the impeller is connected to the rotor shell. The maximum height of the rotor structure is lower than the height of the compression-resistant pillar when the rotor structure is connected to the stator structure.
