基于自控变频理论的直流电动机运行原理新理解

New Understanding of DC Motor's Operating Principle Based upon Self Frequency-control Theory

根据电枢电路自控变数与电流相位自控理论,提出应以直流电动机的自控变频运行机制作为直流电机的核心,直流电动机调节负载时气隙磁场箝位效应维持不变才是直流电动机具有优良控制性能的关键所在。

Suggestion that the DC motor＇ s self frequency-control system should be taken as the core of the DC motor was put forward in accordance with self frequency-control variation and self phase-control theories. When DC motor regulating the load, the clamping effect in the airgap field should be kept unchanged. That was the key factor to realize the excellent controlling performance of the DC motor.
