Abstract
High-efficiency motor drive systems play a crucial role in modern industrial automation, new energy vehicles, and renewable energy power generation. As the demands for energy efficiency and performance continue to increase, traditional motor drive systems face numerous challenges. This study aims to design and optimize a high-efficiency motor drive system to enhance its energy efficiency and dynamic response characteristics. Based on vector control theory and using permanent magnet synchronous motors as the subject of investigation, this research establishes precise mathematical models to thoroughly analyze the internal electromagnetic relationships of the motor. Finite element method simulations are employed to model the motor operation under various operating conditions, while intelligent algorithms are introduced to optimize controller parameters. The results indicate that the designed drive system maintains high power factor and low torque ripple across a wide speed range. Compared with conventional solutions, the efficiency is improved by approximately 15%, and the startup time is reduced by 30%. Additionally, the system exhibits robust performance. Innovatively, this research integrates artificial intelligence technology into the motor control system, achieving adaptive regulation functionality, which provides new insights for improving the overall performance of motor drive systems and holds significant implications for advancing technology in related fields.
