... a small, "smart" sensor tag with a wireless communication interface that is attached to the motor (see gray boxes). The sensor tags can be fitted ex works or retrofitted to motors that have already been installed and provide information on operating parameters such as vibrations, temperature or overload. They also determine the energy consumption with an accuracy of +/- 10 %. The sensor tags send the data wirelessly to secure cloud-based servers from ABB using standard protocols. There, special software analyzes the data and translates it into usable information. Finally, this information about the motor status is ...
