Diagnostics and Prognostics for Linear Electromagnetic Actuators

With increasing machine and component complexity, advanced maintenance strategies become more desirable and necessary. Besides the widely used break-down maintenance (fix it when it breaks) two approaches exist, that try to plan and schedule maintenance. One is preventive maintenance, where components are replaced or maintained based e.g. on a constant time interval, the other one is predictive maintenance. Here the aim is to estimate the current state of health of a component and to predict its remaining useful life based on diagnostic and prognostic methods. Applying condition based maintenance not only reduces downtime and costs, but also increases safety and reliability, which is especially interesting for linear electromagnetic actuators (LEA). They are often used in safety-relevant applications or in inaccessible and harsh operating environments with high performance requirements.
