With the development of the macro voice coil motor, the voice coil motor is a special type of direct drive motor that can directly convert electric energy into linear motion mechanical energy without any transmission mechanism of the intermediate conversion mechanism. The principle is: in a uniform air gap magnetic field into a cylindrical winding, the winding electromagnetically energized to drive the load for linear reciprocating motion, changing the current strength and polarity, you can change the size and direction of the electromagnetic force. Therefore, voice coil motor movement can be straight or rotated. It has high response, high speed, high acceleration, simple structure, small size, good force characteristics, easy control and so on. It is a new technology with new principles and theories in the electrician field since the second half of the 20th century.
Vigorous development of China's advanced manufacturing, voice coil motor industry as its underlying industry, should be given priority to and accelerate the development of voice coil motor for advanced manufacturing of great significance.
At a glance, voice coil motors have a wide range of manufacturing applications including machine tools, measuring, drilling, milling, electronic assembly, grinding, laser cutting, screen printing, semiconductors, adhesive dispensing, wafer processing, labeling Bonding, wire bonding, ion implantation, lithography, textile machinery and more. Through the introduction of voice coil motor control system, not only can greatly improve the processing accuracy and efficiency of these industries, but also reduce the wear and energy consumption, while in the application, but also the industrial upgrading of these industries.
Second, the application of voice coil motors has also contributed to the improvement of the productivity of China's labor-intensive enterprises. Many labor-intensive industries, such as food, battery and toy processing enterprises, usually require a lot of labor. If the production line is upgraded to a voice coil motor-driven automated production line, it will overcome the "shortage of migrant workers" and ease the pressure of rising labor costs , Will play a role.
Then, the development of the voice coil motor industry can quickly narrow the technological gap between our country and the developed countries in the world. Voice coil motor high-speed, high precision, high thrust and other characteristics, determines its hard research in the field of demand. People use voice coil motors to drive maglev trains to over 500 kilometers per hour (km) for speed, catapult an aircraft to hundreds of kilometers in seconds and produce a wide range of components at micron-level precision. Can imagine, without the development of voice coil motor, many high-tech research and development, will be struggling.
In recent years, the voice coil motor has the advantages of simple structure, no contact, high speed, easy control and high precision, which further promote its development and application. In other countries, the application of voice coil motor in the machine bed industry has even become a "hot spot", which has attracted people's attention. We have reason to believe that voice coil motors can quickly be rolled out in a variety of applications.
