Problems solved by technology

Although my country's motor control system has made breakthroughs in some key technologies, it still lacks breakthroughs in overall core technologies. For example, the overall system is not stable and reliable, the information acquisition and measurement devices are relatively simple and backward, and there is a lack of high-precision, high-speed geared motors and Servo motors lack key components such as intelligent drives and controllers. These core technologies play a key role in the performance indicators of the entire control system
