Industry 4.0 is seen as the new era of manufacturing, combining technology, robotics, artificial intelligence, and automation to create an efficient and effective manufacturing process. Industrial use cases represent 37% of the energy used worldwide, with 70% consumed by motors. If motors run at maximum efficiency, a 10% reduction in global electricity use is possible. But what does that mean? Increasing operational efficiency through condition-based monitoring and predictive maintenance (CbM/PdM) can significantly enhance business performance in terms of productivity, quality, and logistics management—helping companies meet sustainability metrics and other strategic goals. Analog Devices OtoSense™ Smart Motor Sensor (SMS) technology is one of the leading CbM/PdM technologies in the market today. This article outlines how OtoSense SMS technology can make electric motor operation more energy efficient.
