摘要
主要讨论了永磁直流电机的动态特性理论和测量。动态特性研究的是电动机怎样响应运行指令。首先按普通直流电机的参数讨论了效电路的推导,并把摩擦负载和转动惯量等机械参数也转化成等效电路的电参数。然后按不同的条件求出来它的传递函数。最后提出了动态特性参数的测量方法。
This paper focuses on the theory and measurement of dynamic characteristics of permanent-magnet DC motors. The dynamic characteristics refer to how a motor responds to operational commands. When considering the dynamic characteristics, it is convenient to represent motor by an equivalent circuit. The paper discusses the derivation of equivalent circuit of permanent-magnet DC motors from the motor parameters, transforms mechanical parameters to electronic circuit parameters, and derives their transfer functions under various conditions. Finally, the paper presents the measurement of the parameters of dynamic characteristics.
