In the automotive world new technologies are entering the market with great potentialities of becoming the future dominant design. These technologies are based on electric traction system cooperating or not with classic combustion engine. In this innovation phase, it is fundamental to fill the gap between old technologies with new ones. For this reason new components and features have to be introduced in the future traction system. In this case study an innovative electromechanical actuator for safety purpose is proposed to be added in the electric traction system. It needs specific conditions to be actuated which are monitored through electric machine parameters.
