无自转现象。正常运转的伺服电动机，只要失去控制电压，电机立即停止运转。当伺服电动机失去控制电压后，它处于单相运行状态，由于转子电阻大，定子中两个相反方向旋转的旋转磁场与转子作用所产生的两个转矩特性（t1－s1、t2－s2曲线）以及合成转矩特性（t－s曲线） 运行范围较广。
伺服电动机在没有控制电压时，定子内只有励磁绕组产生的脉动磁场，转子静止不动。当有控制电压时，定子内便产生一个旋转磁场，在负载恒定的情况下，电动机的转速随控制电压的大小而变化，当控制电压的相位相反时，伺服电动机将反转。

伺服电机又称执行电机，它是控制电机的一种。它是一种用电脉冲信号进行控制的，并将脉冲信号转变成相应的角位移或直线位移和角速度的执行元件。
当今科技发展迅猛，新知识、新技术、新工艺、新产品层出不穷，传统的电机拖动系统不断的被更新和改造。伺服驱动装置在冲压车间传输系统和自动化设备中一直有可靠的应用，现在，该装置在压力机的主驱动装置上也得到了应用。功率更高的伺服驱动装置应用于冲压成形过程，具有更大的灵活性。在某种程度上，变化着的压力机概念既相互竞争，同时也相互互补，不存在普遍适用的解决办法。客户在冲压和质量方面的具体要求、内部的专门技术以及生产和物流方面的要求产生了各种不同的冲压车间。利用PLC可以直接对伺服电机进行位置和速度控制，无需增加定位模块，节约成本。
