The functional interface between information processing—in the form of electrical signals—and mechanical structure—in the form of forces/torques and motion variables—is of key importance in a mechatronic product. The bi-directional conversion of energy from electrical to mechanical is a key component of the primary product task “perform purposeful motions”. The multiple, diverse conversion principles available today can also be integrated into a mechatronic product in a functionally and physically compact manner in the form of
. Along with a basic grasp of these conversion principles, understanding the influences which parameters describing the transducer have on its transfer characteristics is of particular interest in systems design.
