Abstract

Develop new high-performance permanent magnet materials, such as rare earth permanent magnet materials with higher remanence and coercivity, optimize the magnetic circuit structure and winding design of motors, output greater power within the same space, and meet the power industry's demand for compact and high-performance equipment.

Research and develop new high-performance permanent magnet materials, such as rare earth permanent magnet materials with higher remanence and coercivity, optimize the magnetic circuit structure and winding design of motors to output greater power within the same space, meeting the power industry's demand for compact and high-performance equipment. Utilize advanced electromagnetic design methods and optimization algorithms, combined with multi-physical field coupling analysis to reduce iron loss, copper loss, eddy current loss, etc.; at the same time, develop efficient cooling technologies and heat dissipation structures, such as microchannel cooling, evaporative cooling, etc., to ensure the efficient operation of motors. Leverage improved innovative power electronics technology and control strategies, such as vector control, direct torque control, and the application of intelligent control algorithms, to achieve a wider speed regulation range and more precise speed control, allowing the motor to operate flexibly under different working conditions in the power system. Explore the use of high-strength, high-conductivity, and high-thermal-conductivity non-magnetic materials for motor structural components and windings, such as carbon fiber composites for rotor support structures or sheath materials; develop new insulation materials to improve insulation and high-temperature resistance, ensuring the safe operation of motors.

Additive manufacturing (3D printing) technology will be more widely applied in the manufacturing of ultra-high-speed permanent magnet motors, enabling complex structural designs, improving manufacturing precision and production efficiency, reducing costs, and meeting personalized customization needs. Use high-precision processing equipment and advanced processes such as precision grinding, electrical discharge machining, and laser processing to ensure the processing accuracy and surface quality of components; utilize automated production lines and robotics technology to achieve automated production, improving efficiency and product quality consistency. Artificial intelligence and machine learning technologies are deeply integrated into control, establishing accurate models, combining real-time monitoring data, and utilizing intelligent control algorithms such as model predictive control and deep learning to achieve adaptive control and optimized operation, as well as intelligent fault diagnosis and predictive maintenance. Develop integrated systems to achieve real-time monitoring and collaborative control of multiple parameters of high-speed permanent magnet motors, adding monitoring of parameters such as motor vibration, stress, and magnetic field distribution in addition to traditional parameter monitoring, through sensor fusion technology and advanced signal processing methods, to comprehensively grasp the operating status and optimize control.

As offshore wind power develops into deeper waters, high-speed permanent magnet motors, with their advantages of not requiring gearboxes and high reliability, will see increased applications in offshore wind turbine generators, aiding the large-scale development of offshore wind power. In distributed generation scenarios, such as driving auxiliary equipment in small solar power stations, high-speed permanent magnet motors will demonstrate their efficient and flexible characteristics, improving the overall performance of distributed energy systems, and their applications will become more widespread. In new energy storage technologies such as flow battery storage and hydrogen energy storage, high-speed permanent magnet motors are expected to gain new application opportunities due to their high-speed operation and precise control, promoting the development of energy storage technology. Deeply integrated with distributed generation systems such as solar and wind energy, as well as energy storage systems, they serve as driving motors for generating equipment to improve power generation efficiency, working in conjunction with energy storage systems to achieve efficient energy storage and release, optimizing the operational performance of energy systems. They mutually promote advancements in power electronics technology, new materials technology, advanced manufacturing technology, and intelligent control technology, such as power electronics technology providing more efficient and reliable variable frequency speed control devices and drive systems, jointly driving technological development.
