The main conclusion of this study is that for all cases analysed the energy used for the digitalisation of the motor systems is with less than 1% negligible. On an overall level, the energy savings achieved through the digitalisation of motor systems far outweigh the additional energy consumption resulting from the digitalisation process. In the cases studied, what is decisive for the savings potential is to what extent systems were already optimised before the measures and to what extent measures can contribute to an optimised system operation.
