    In regards to electrical motion control, the term “closed-loop” is best described by which of the following possible answers?

    • A. 

      Soft Starts

      Centralized Control

    • E. 

      Harry Jenkins

    Correct Answer
    C. Feedback
    Explanation
    While Control Techniques’ Charlotte-based Applications Engineer, Harry Jenkins, could probably “describe” the concept of open-loop/closed-loop very well, the correct answer is Feedback. Devices such as encoders and resolvers can provide the necessary feedback to the drive. This adds cost to the system but will also help to more accurately maintain a motor’s desired position or speed. Conversely, an electrical motion application that provides position control but doesn’t utilize feedback is referred to as an “open loop.”
