A stepper motor is an electromechanical device that converts electrical pulses into motion.

5. The force output of an electrical actuator is determined by the flowing through it.

The main advantage of servo motors is their in controlling position.

The speed of a servo motor is determined by the of the control signal.

Delay is the time difference between the input and output signals caused by time.

Delay can introduce shifts in the system response.

Steady state error can be reduced by improving the performance.
