Abstract:
The present invention provides a blade structure used in a blower to not only increase the wind pressure and gas quantity but also reduce the noise. The blade structure includes a vane group constituted by a plurality of vanes. A plurality of inclined portions is also included in the blade structure. Each of the plurality of the inclined portions is connected to each of the plurality of vanes of the vane group.
Abstract:
A fastening structure for securing a stator of a motor includes a sleeve with a cut portion formed thereon and a fastener. The fastener is composed of a position section and an engaging section, wherein the engaging section engages with the cut portion and the position section presses on the top surfaces of the coil bobbin of the stator.
Abstract:
A motor having a magnetic bearing. The motor includes a base provided with a bearing seats, a stator fixed to the base, a rotor equipped with a rotation shaft and able to rotate relative to the stator by magnetic forces generated from excitation, a bearing fastened to the bearing seat of the base for accommodating the rotation shaft of the rotor, and a magnetic unit composed of a first, a second and a third magnetic elements. The second magnetic element is located below the first magnetic element. The third magnetic element is located below the second magnetic element. By employing the magnetic force, the second magnetic element is restrained between the first and third magnetic elements, thereby limiting a shift range of the rotation shaft.
Abstract:
The invention provides a heat-dissipating assembly and a securing device used therein, which utilizes a way of securing by applying force in one direction to prevent the surface of a chip from being damaged. The securing device includes a frame body having a plurality of first fasteners fastened to a socket by the first fasteners; and a wrenching member pivotally coupled to the frame body, wherein after applying an external force on the wrenching member in one direction, the heat-dissipating device can be fixed tightly on the socket.
Abstract:
A fin structure is disclosed. The fin structure includes a first concavo-convex portion formed with a concave on a first surface of the fin in the direction of thickness and a corresponding convex on a second surface of the fin in the direction of thickness. Besides, a second concavo-convex portion formed with a first concave and second concave on the first surface of the fin in the direction of thickness and a corresponding first convex and a corresponding second convex on the second surface of the fin in the direction of thickness is included as well. Specifically, the first and second concavo-convex portions are symmetrical respect to the center of the fin. Furthermore, the second convex of the second concavo-convex portion on one fin can be exactly received by the concave of the first concavo-convex portion on another fin.
Abstract:
An air-guiding impeller for a blower. The impeller includes a rotary shaft adaptable for a motor, an annular frame, blades formed on the annular frame, and air-guiding ribs interconnected between the annular frame and the rotary shaft and inclined with respect to the annular frame.
Abstract:
A serial fan includes a frame, a plurality of rotor vanes, a support connected to the frame through a plurality of connecting parts. The plurality of rotor vanes are arranged in series in the frame along an axial direction and the plurality of connecting parts are disposed therebetween to minimize space occupied by the serial fan in the axial direction, and effectively increase the blast pressure.
Abstract:
A heat-dissipating device and a housing thereof. The housing includes a passage for guiding an air stream flowing from an opening to another opening, wherein an sidewall of the passage at least one of the opening sides extends radially outwards with a rotational axis of the heat-dissipating device or the passage so as to enlarge intake or discharge area for the air streams. Accordingly, the intake airflow rate may be greatly increased and the heat-dissipating efficiency of the heat-dissipating device may be greatly enhanced without changing assembling conditions with other elements.
Abstract:
A fastening structure for securing a stator of a motor includes a copper sleeve with a notch thereon and a fastener. The fastener is composed of a position section and a hook section, wherein the hook section engages with the notch and the position section presses on the top surfaces of the coil bobbin of the stator.
Abstract:
A motor structure includes a stator and a rotor. The stator includes a coil assembly which includes a ring-shaped slot having an inner periphery on its inner side and an outer periphery on its outer side away from the inner periphery, a plurality of first teeth mounted around the inner periphery of the ring-shaped slot, and a plurality of second teeth mounted around the outer periphery of the ring-shaped slot; wherein each of the first teeth is arranged to partly fall behind or exceed the corresponding one of the second teeth, and a coil wound in the ring-shaped slot. The rotor includes a circular magnet located above the coil.
