Description
Servo motors are drivers that accurately control position, speed, acceleration, etc. according to command signals and are mainly used in processes that require precise control, such as semiconductor processes. The precision of servomotors used in precision processes determines the completeness of the final product and accounts for the main power consumption excluding the heating process within the production line. In order to develop servo motors, it is necessary to improve commercialization technology through technology development such as ensuring compatibility, miniaturization/lightweight, and performance improvement. In order to respond to climate change caused by carbon emissions, efforts are being made to legislate emission reduction through international agreements and policies such as the Glasgow Climate Agreement. According to the top 10 carbon emitting countries, carbon emissions generated by global manufacturing powers China, the United States, Japan, Germany, and Korea account for more than 50
