A server motor loop is a closed system which is operated by control signals. And these are being used in black boxes as an electronic controller. So the answer is it operates independently from any item attached to the motor.

a variable frequency drive can be used on the following industrial devices: a- AC motor b- DC motor c- DC Servo Motor d- All of the above
A control system that anticipates load 7 Problem 1: Select the most correct answer disturbances and controls them before they can impact the process variable is of this type Open loop controllers have this characteristic: 1 They don't use feedback Open loop control system Feedback control system a b. They don't observe the output Can't compensate for disturbance All of the above b. Feedforward control system d. None of the above This is an example of an open-loop system 8....
In open-loop control: Group of answer choices Results in very small deviations from the optimum variable of the process variable The open-loop system does not self correct when the process variable drifts The system is totally immune to external disturbances The input signal to the controller depends on the actual value of the output variable
le Edit View Win 5. A d.c. motor powered from an amplifier was set up in the laboratory and subjected to a step response test. The input to the amplifier was suddenly increased from 0 volts to 5 volts and the output speed of the motor was measured and plotted, see the attached Figure Q5 a. Draw a block diagram representation for the system. b. Judging from the plot of the step response, Figure Q5, what would you guess is...

Simplifying, gives...
2. We wish to control the speed of the tumbler in a clothes dryer. To do this we must first find the transfer of the open loop system. A permanent magnet DC motor (armature controlled) is used to drive the tumbler. A power amplifier is used to drive the motor. A voltage proportional to the desired speed of the tumbler is applied at the amplifier input. a. Identify the inputs and outputs of this system. b. Identify the components. c....
