Another very useful application of power monitors is to improve the efficiency of motors, be it Brushed or Brushless DC motors. They amount to 60 to 70% of the entire industrial electricity consumption globally, so they deserve great attention because each % of improvement can avoid energy wastage. Furthermore, these are very expensive equipment in critical applications where a downtime can be extremely expensive. So, preventive maintenance is done continuously to predict when the motor bearings are going to fail can save a lot of money and inconvenience on the long term. Motors that are starting to fail can be detected thanks to their power signature, and hence avoid important accidents. There are multiple ways of doing this, with some that are very advanced and expensive. However, using a power monitoring IC such as the ACS37800 allows the customer limited cost in higher power applications. Additionally, the ACS37800 provides exhaustive information with the active, reactive and apparent power as well as power average that allow a more precise diagnostics for the user.
