Designing transducers or motors, requires the analysis of a lot of parameters such as length, temperature, efficiency, weight, etc. The solution to obtain the optimum results for given specifications is to analyze globally all the free parameters in one go, with an optimization algorithm based on the "Prodesign" software, including its optimization module, developed by the INPG in Grenoble (France). A general module makes it possible then to get the optimum according to the constraints of the problem. In future, a module for each type of transducer or motor as well as a module for the driver is developed
