High-Precision Torque Control of Dual Three-Phase PMSM

With the continuous innovation of power electronics and automation control technology, China's industrial modernization process has been significantly accelerated, and more people can experience the improvement of modern industrial products on the quality of life. In order to realize the sustainable development of society and economy in China, permanent magnet synchronous motors are widely used in various fields of social production and life, such as industrial automation, home appliances, transportation, aerospace and other occasions. The State Council has set a clear target: by 2030, China's carbon emissions per unit of GDP should be cut by more than 65% compared with 2005, so as to achieve the ambitious goal of "carbon peak". In order to achieve the grand goal of "carbon peak" as soon as possible, at present, major enterprises in China are actively promoting the upgrading of key energy-consuming equipment such as motors, giving priority to the adoption of high-efficiency and energy-saving motors, and accelerating the elimination of backward and inefficient motors that do not meet the current national energy efficiency standards.
