 伺服电动机servomotor    用作自动控制装置中执行元件的微特电机。又称执行电动机。其功能是将电信号转换成转轴的角位移或角速度。   伺服电动机分交、直流两类。交流伺服电动机的工作原理与交流感应电动机相同。在定子上有两个相空间位移90°电角度的励磁绕组Wf和控制绕组WcoWf接一恒定交流电压，利用施加到Wc上的交流电压或相位的变化，达到控制电动机运行的目的。交流伺服电动机具有运行稳定、可控性好、响应快速、灵敏度高以及机械特性和调节特性的非线性度指标严格（要求分别小于10％～15％和小于15％～25％）等特点。直流伺服电动机的工作原理与一般直流电动机相同。电动机转速n为   n＝E／K1j＝（Ua－IaRa）／K1j式中E为电枢反电动势；K为常数；j为每极磁通；Ua，Ia为电枢电压和电枢电流；Ra为电枢电阻。改变Ua或改变φ，均可控制直流伺服电动机的转速，但一般采用控制电枢电压的方法。在永磁式直流伺服电动机中，励磁绕组被永久磁铁所取代，磁通φ恒定。   直流伺服电动机具有良好的线性调节特性及快速的时间响应。
