  In electrical engineering the technical terms “servomotor” and “servo control system” are used since long decades ago. They are generally accepted and wide-range used denominations worldwide in scientific papers, books, advertisements and other publications. In other words, the above two terms become somewhat self-understanding incontestable parts of our technical language. However, this paper emphasizes the idea to discuss the exact and real meaning of these two terms. This because often it happens that in scientific publications there is no made clear difference between the terms “motor” or “servomotor”, respectively “control system” or “servo control system” and that may be a real source of misunderstandings or confusions. For this reason, in first step a thorough overview of the available international scientific literature is presented in the paper in order to evidence the context and conditions in that are used the discussed scientific expressions. Then a careful analysis from technical point of view is unfolded to bring arguments to strengthen the endeavor that a clear difference should be made between the terms “motor” and “servomotor”, respectively “control system” and “servo control system” in demanding technical discussions, as well as in scientific publications. Not at least, there is proposed an original definition of the two discussed terms, reflecting a point of view that may contribute to better understanding and utilization in scientific debates and publications.
