Abstract

永磁无刷伺服电机的换相和控制都需要准确的转子位置信息 ,然而位置传感器有其难以克服的缺点。文章综述了各种电机的一些位置估计方法 ,分析了其优缺点 ,这些方法在很大程度上可取代位置传感器。最后对将来的位置估计方法发展方向作了展望。||The exact rotor position is required while a permanent magnet brushless servo motor (PMBSM) is under commutation and control.Howere,position sensors have some fatal defects.This paper reviewed the position estimation methods of various motors and analyzed their advantages and disadvantages.By using these methods,position sensors can be eliminated to a great extent.At the end a forecast on position extimation technique in the future is presented.
