Voice coil motor: "position, enhance the times." The theme of this year's annual meeting is “Position, Enhancing Times”, emphasizing the integration of high-precision time and space information enhancement services with mobile communications, the Internet, the Internet of Things, and big data to help the information industry, manufacturing, and service industries enter the field. Strengthen the times.

     The Beidou augmentation system is also evolving, which will further improve positioning accuracy and guide users through the “last centimeter”. According to Yang Changfeng, chief designer of the BeiDou satellite navigation system, China will provide 7×24-hour highly-available dynamic centimeter-level positioning services for areas including network coverage and desert-free areas covered by networks. Compared with a single satellite-based system, the service's first positioning time will be reduced by more than 97%, positioning accuracy can be increased by 50%, and the service availability rate can reach 99.99%. It will be applied to personal and production safety applications such as autopilot and drones. Plays an important role in empowering the global smart IoT application industry ecosystem.

     BeiDou Ground-Based Reinforcement System was officially launched in September 2014. It has completed the basic system development and construction, and has the ability to provide wide-area real-time meters, decimeters, centimeters, and post-processing millimeter-level positioning accuracy.

     The voice coil motor  is a special form of direct drive motor that converts electrical energy directly into linear motion mechanical energy without the need for any intermediate conversion mechanism transmission. The principle is: a cylindrical winding is placed in a uniform air gap magnetic field, the winding is energized to generate electromagnetic force to drive the load to make a linear reciprocating motion, and the magnitude and direction of the electromagnetic force can be changed by changing the strength and polarity of the current. Therefore, the voice coil motor (voice coil motor) can be linear or rotational. The utility model has the advantages of high response, high speed, high acceleration, simple structure, small volume, good force characteristics and convenient control.
