Composite material double-body rotor for light motor

Abstract

The invention provides a composite material double-body rotor for a light motor. The composite material double-body rotor comprises a light driving layer, an operation tool layer and a substrate, wherein the light driving layer is made of a small-density material; the operation tool layer is made of a large-density material; the light driving layer comprises a rotating shaft and an upper rotor; the operation tool layer comprises a lower layer rotor and a pointed rotating shaft; the upper rotor is positioned at the upper end of the rotating shaft; the lower layer rotor is positioned at the lower end of the rotating shaft; and the pointed rotating shaft is connected to the lower top end of the rotating shaft and is embedded into a small conical hole of which the pore diameter is a little larger than the shaft diameter of the rotating shaft on the substrate. The rotor can rotate stably; meanwhile, the problem of the limits of driving and function on the quantity of single rotor wings is solved; and due to the adoption of the double-body rotor, an optimal effect can be achieved. Due to different structures of a rotor functional layer, functions such as microflow stirring, a micropump,measurement of microcosmic tension, micro-structure winding and the like can be realized, and a powerful tool is provided for micro-life science and biomedicine.

Description

technical field [0001] The invention relates to a composite double-body rotor for an optical motor. Background technique [0002] Photoinduced rotation is an effective means to realize micro-mechanical motors. With the development of science and technology, as well as the development of processing technology and computer technology, the application prospect of photoinduced rotation will become more and more extensive. The method of photoinduced rotation can not only be applied to micro total analysis As a stirrer in the system, it can also be applied to micropumps, and can also be used to study rotating motor proteins, microscopic properties of fluids, and cell membrane shear forces. A powerful tool. [0003] In 1936, R.A.Beth experimentally let a beam of circularly polarized light pass through a half-wave plate suspended by a filament, and used the angular momentum of photons in the beam to realize the rotation of an object for the first time (Beth R A. Mechanical detectio...

Problems solved by technology

[0008] Many universities around the world have done a lot of research on the design of the rotor shape based on the principle of "windmill-like rotation", and have made great progress and good research results. However, there are still problems such as the rotor cannot rotate stably. In order to obtain a better High torsional torque at the expense of functional range, etc.
