永磁同步电动机英文翻译中英文翻译0 英文原文Research on Voltage Space-vector Control System of Synchronous Motor Vector control of field oriented control, the basic idea is: through coordinate transformation control method for simulation of DC motor to control the permanent magnet synchronous motor. Three-phase symmetrical windings in three-phase AC can produce a rotating magnetic motive force, two phase symmetrical windings into two symmetric alternating current can produce the same rotating magnet ometive force; therefore the three-phase symmetric winding can be replaced with two phase symmetrical windings equivalent independent of each other, equivalent principle is the constant magnetomotive force produced before and after transformation, transformation and total power constant. In oil field, the power factor was reduced and the reactive power consumption was increased because of the usage of the large number of asynchronous motor, and resulting in a huge waste of energy, which reduced the integrated cost-effective of field. The permanent magnet synchronous motor possess all the advantages of synchronous motor and it has high efficiency and higher power factor. For the advantages of permanent magnet synchronous,it will bring good energy saving results if it is used in pumping unit. As a result,the study on permanent magnet synchronous motor control system is important. In this paper the theory of vector control system on PMSM is first deeply studied,and the idea of coordinate transformation is used to build the mathematical model of PMSM. An in-depth theoretical analysis of voltage space vector control algorithm is done. Secondly,based on the mathematical model of permanent magnet synchronous motor and SVPWM theory,...
