10 ADI | Engineering a More Sustainable Future The Important Role of Motor Energy Regulations Intelligent motion control solutions are delivering and will continue to deliver significant reductions in energy consumption by moving more applications from fixed speed motors to high efficiency motors and VSDs, in part driven by energy efficiency regulations. This reduction in energy consumption will enable more sustainable manufacturing with reduced CO 2 emissions. To accelerate the deployment of higher efficiency motor driven systems, the International Electrotechnical Commission ( IEC ) has contributed to the definition of energy-efficient electric motor standards. This includes the IEC 60034-2-1 test standard for electric motors and the IEC 60034-30-1 classification scheme comprised of four levels of motor efficiency ( IE1 through IE4 ) . These standards have made it easier to compare efficiency levels between motor manufacturers. They also provide a reference for governments to specify the efficiency levels for their minimum energy performance standards ( MEPS ) , helping countries to meet their energy efficiency and carbon dioxide emissions targets. IEC 60034-1 Efficiency Classes: X IE1 Standard Efficiency X IE2 High Efficiency X IE3 Premium Efficiency X IE4 Super Premium Efficiency Significant progress has been made by governments worldwide to set MEPS for motors. Since 2020, countries consuming 76% of global electric motor system electricity have introduced MEPS for motors at either the IE2 or IE3 level, contributing to reduced industrial electricity consumption. 5 In the EU, since July 1, 2021, a minimum efficiency class of IE3 ( Premium Efficiency ) is required for motors from 0.75 kW to 1000 kW. A minimum of IE2 ( High Efficiency ) is required for smaller motors from 0.12 kW to 0.75 kW. Starting July 1, 2023, the MEPS will increase to IE4 ( Super Premium Efficiency ) for motors between 75 kW and 200 kW in the EU. When we look at the total cost of ownership of a motor driven system over the life of its deployment, 70% of the total cost is electricity compared to 5% for the purchase of the motor and 20% for the maintenance of the motors (see Figure 3). 6 Therefore, by deploying more efficient motion driven systems, we can significantly reduce the operation cost of industrial motors while also reducing CO2 emissions. Digital Transformation Strategies to Deliver Increased Manufacturing Efficiency VSDs use data from voltages, currents, position, temperature, power, and energy consumption combined with external sensors for monitoring vibration, and other process variables. With a converged information technology/operating technology (IT/OT) Ethernet network, motion applications are networked together communicating data and motion insights to cloud- based data storage or on-premises storage. Motion data and insights are now more accessible and can be analyzed by powerful cloud computing and artificial intelligence (AI) to optimize manufacturing flows, reducing the energy consumption and CO2 emissions created in manufacturing. Access to motion insights extends equipment lifespans, improves manufacturing quality, and reduces unplanned downtime and material wastage while increasing safety in manufacturing plants.
