The servo motor works differently. It analyzes the position error with great frequency, i.e. the difference between the set position and the current one (e.g. from a measuring ruler). The microprocessor in the controller tries to control the torque, i.e. the motor current, so that the position error is as small as possible. Due to the fact that the current overload of servo drives reaches ten times the nominal value, the perceived power of a machine equipped with servo drives of a size similar to stepper motors is many times greater.
