Embodiment 1

[0021] The invention provides a micro-motor system excited by a magnetic field. Such as figure 1 As shown, the micromotor system excited by the magnetic field includes a first magnetostrictive layer 1 , a second magnetostrictive layer 2 , and a microrod 3 . The second magnetostrictive layer 2 is placed on the first magnetostrictive layer 1 . The materials of the first magnetostrictive layer 1 and the second magnetostrictive layer 2 are nickel alloy, iron-based alloy and ferrite material. The second magnetostrictive layer 2 is composed of periodically arranged micron blocks. Microblocks are square. The period of the microblocks is a square period. The distance between adjacent micro-blocks is greater than 1 micron and less than 10 microns, which not only ensures sufficient expansion and contraction of the micro-blocks, but also makes full use of the space on the first magnetostrictive layer 1 . Microrods 3 are placed vertically on the microblock. That is, the bottom of th...

Embodiment 2

[0025] On the basis of Example 1, the microrods 3 are asymmetrically placed on the microblock. That is, the bottom of the microrod 3 deviates from the center of the microblock. The position of each microrod 3 relative to the microblock is different. In this way, under the action of an external magnetic field, the direction of the force on the fixed end of each microrod 3 is different, which can drive the microrod 3 to vibrate in different directions, which is conducive to the release of air bubbles in the fields of photolysis of water and hydrogen production. .

Embodiment 3

[0027] On the basis of Example 2, such as figure 2 As shown, the microrod 3 is placed obliquely on the microblock. In this way, the microrods 3 are more likely to bend relative to the microblocks, so that the microrods 3 vibrate with a greater magnitude, and achieve higher efficiency conversion of magnetic energy to mechanical energy.

Abstract

The invention provides a magnetic field excited micro-motor system, which comprises a first magnetostriction layer, a second magnetostriction layer and micron rods, wherein the second magnetostrictionlayer is arranged on the first magnetostriction layer, the second magnetostriction layer is composed of micron blocks arranged periodically, and the micron rods are vertically arranged on the micronblocks. Under the action of a magnetic field, the first magnetostriction layer and the second magnetostriction layer stretch out and draw back and act on the microrods through the bottoms of the microrods, so that the microrods vibrate. According to the invention, the separated magnetostriction micron blocks are arranged on the magnetostriction layer, so that the micron blocks can stretch out anddraw back to a greater extent so as to improve the conversion efficiency of magnetic energy and mechanical energy; and the magnetic field excited micro-motor system has good application prospects in the fields of micro-nano machinery and magnetic energy and mechanical energy conversion.

technical field [0001] The invention relates to the technical field of micro-motors, in particular to a micro-motor system excited by a magnetic field. Background technique [0002] Micro-motor systems have a wide range of applications in the fields of micro-nano machinery, clinical medicine, and environmental governance. The magnetic field has good penetration, and the micro-motor based on the magnetic field has a good application prospect. The magneto-mechanical energy conversion efficiency in the prior art is low, which limits the application of the micro-motor system based on the magnetic field. Contents of the invention [0003] In order to solve the above problems, the present invention provides a micro-motor system excited by a magnetic field, comprising: a first magnetostrictive layer, a second magnetostrictive layer, microrods, and the second magnetostrictive layer is placed on the first magnetostrictive layer. On the layer, the second magnetostrictive layer is ...
