Zustandsüberwachung eines galvanometrischen antriebs unter verwendung eines neuartigen wärmetransportmodells

New control algorithms for a galvanometer laser scanner enhance the system’s dynamics, but an exceptionally high capacity utilization of the components may cause a thermal overload and damage the drives. In this article, we present a possibility for condition monitor- ing of scanner systems, based on an approximative heat transfer model of the drives, which requires less computing power. In addition, the initial parameters can be taken from datasheets. With the presented methodology the temperature within the galvanometric drive can be estimated. Thus, it is possible to respond to the danger, if a critical value is exceeded.
