DC servo motorBasic product features:
　　
1. There is a transitional process in the dynamic characteristics from the original stable state to the new stable state, which isDC servo motorThe dynamic characteristics.
　　
2. The law that the mechanical characteristics of the motor's speed n changes with the electromagnetic torque M when the input armature voltage Ua remains constant is calledDC servo motorThe mechanical characteristics.
　　
3. The law that the steady-state speed n of a DC motor varies with the control voltage Ua of the armature under a certain electromagnetic torque M (or load torque) is calledDC servo motorThe regulating characteristics.
