In recent years, with the rapid development of power electronics, microelectronics, new motor control theory and rare-earth permanent magnet, permanent magnet synchronous motor has been widely applied. The national development and Reform Commission, the Ministry of industry and information and the Ministry of finance are also promoting efficient and energy-saving motors. Our company's permanent magnet synchronous motor (PMSM) is successfully developed with the advanced equipment Research Institute of Tsinghua University.
Compared with the traditional electric excitation synchronous motor, permanent magnet synchronous motor (PMSM) has the advantages of small loss, high efficiency and obvious power saving effect. It provides excitation to the permanent magnet, the motor has simple structure, reduces processing and assembly costs, and prone to problems with collecting ring and brush omitted, improve the reliability of motor operation; and because no excitation current, no excitation loss, improve motor efficiency and power density, so it is a a motor in recent years in various fields more and more widely used.
Permanent magnet synchronous motor debugging success, marking our factory can fully accept energy-saving national key projects, let us enter the high-end market all the way, at the same time we enter the field of aerospace dream of sailing began to gradually become a reality.
