摘要: 本文從電機的基本矩陣方程入手,用座標變換方法推得了無換向器電動機的數學模型及其簡化傳遞函數,討論了一些物理量對其動特性的影響,闡明了無換向器電動機閉環控制系統的組成與特性,提出了改善動態特性的方法。研究結果表明,簡化傳遞函數具有足夠的準確性;無換向器電動機閉環控制系統具有與直流電動機閉環控制系統極其相似的動態性能;采用磁場調節與電樞調節相結合的控制方式,可以使系統的動態性能得到很大改善。Abstract: In this paper starting with the basic matrix equations of the motor,we xamined and obtained the mathematical model of the Commutatorless Motor and consequently its simplified transfer function The effects of some factors on the dynamic characteristics of the Commutatorless Motor were discussed. The structure and the characteristics of closed loop control system of the Commutatorless Motor were expounded,some methods were also presented to improve the dynamic characteristics of the system.
