    • A single-phase induction motor and a method for reducing noise in the same, which can eliminate unbalance between magnetomotive forces of main and auxiliary windings in a stator of the motor, thereby implementing a low noise, low vibration motor, and can also achieve balance between the magnetomotive forces of the stator windings in the entire running range of the motor, and can further achieve balance between the magnetomotive forces of the stator windings on the basis of temperature increase of the motor as it runs. The amplitude of a main-winding current flowing through the main winding in the stator is controlled to be equal to the amplitude of an auxiliary-winding current flowing through the auxiliary winding in the stator, and the phase difference between the main-winding and auxiliary-winding currents is controlled to be maintained at a predetermined value.

    • A method for fabrication of nanometer scale metal fibers, followed by optional further processing into cables, yarns and textiles composed of the primary nanofibers. A multicomponent composite is first formed by drilling a billet of matrix metal, and inserting rods of the metal desired as nanofibers. Hexed or round rods can also be inserted into a matrix metal can. The diameter of this composite is then reduced by mechanical deformation methods. This composite is then cut to shorter lengths and reinserted into another billet of matrix metal, and again the diameter is reduced by mechanical deformation. This process of large scale metal stacking followed by mechanical deformation is repeated until the desired fiber size scale is reached, the fibers being contained in the matrix metal. After size reduction, the composite metal wires may be further processed into built up configurations, depending on intended application, by stranding, cabling, braiding, weaving, knitting, felting, etc., to form yarns or textiles. After the built up configuration is formed, the matrix metal is removed by chemical etching, leaving a cable, yarn or textile composed of the primary nanofibers.
    • 一种用于制造纳米级金属纤维的方法,随后可选地进一步加工成由初级纳米纤维组成的电缆,纱线和纺织品。 首先通过钻取基体金属坯料,并将所需金属棒作为纳米纤维插入,形成多组分复合材料。 六边形或圆形的杆也可插入矩阵金属罐中。 然后通过机械变形方法减小该复合材料的直径。 然后将该复合材料切割成更短的长度并重新插入到另一个基体金属坯料中,再次通过机械变形减小直径。 重复这种大规模金属堆叠的机械变形过程,直到达到所需的纤维尺寸,纤维被包含在基质金属中。 尺寸缩小后,复合金属丝可根据用途,绞合,电缆布线,编织,编织,编织,毡化等进一步加工成内衬构造,以形成纱线或纺织品。 在形成构建构造之后,通过化学蚀刻去除基质金属,留下由初级纳米纤维组成的电缆,纱线或纺织物。
