磁链轨迹法在变频调速系统中的应用
Application of magnetic flux linkage track in frequency speed conversion system
摘要
Abstract
In order to investigate the various frequency speed conversion methods of electric motor and develop a more feasible and simplified system, this paper presents a method of speed conversion through the integration of the electric motor inverter and electric motor. By changing the working mode of electric motor inverter, there will be a set of voltage space vector produced with polygonal magnetic flux linkage which approximates an ideal regular polygon. The rotating angle of the flux linkage can be changed by inserting zero voltage vector. Therefore, the frequency speed conversion is achieved. The result indicates that the system is based on a clear conception with simply systematic structure and can be easily implemented by a computer.关键词
