The reporter learned from CSIC 712 Institute learned that the first set of on-board installation of permanent magnet propulsion motor car developed by the Institute marked the success of China's first permanent magnet propulsion motor with complete independent intellectual property rights An important step forward means that our ship propulsion technology has reached the world advanced level.
Permanent magnet propulsion technology to a new type of permanent magnet motor based on the integration of the design of permanent magnet motor technology, modern high-power power electronics and real-time computer control technology, in recent years, the performance of permanent magnetic materials, especially magnetic properties, thermal stability And corrosion resistance has been significantly improved, the preparation and application of power electronic devices gradually mature, permanent magnet motor design methods, control technology and manufacturing processes are also rapid development of synchronization, and quickly promote the development and application of permanent magnet propulsion technology.
According to reports, permanent magnet motor with permanent magnetic materials and frequency control device to replace the traditional motor excitation, commutation and voltage regulator and other devices, which makes the permanent magnet propulsion motor with small size, light weight, low noise, high efficiency, Simple operation and easy maintenance, which will contribute to the improvement of ship performance.PLC has become one of the landmark technologies of ships and is the main direction of ship propulsion technology development in the future.
During the "12th Five-Year Plan" period, seven hundred and twelve projects of permanent magnetism propulsion system were completed, and long-term reliability test and real-burst impact test were conducted, which fully released the risk of equipment loading. According to the person in charge of the project, In the next few years, the permanent magnet motor propulsion system will be popularized and applied to realize the leap-forward development of China's ship propulsion technology.
