In the context of Vietnam’s economy undergoing deep integration with the region and the world, the energy demand for industrial production is growing robustly. The industrial sector currently accounts for nearly 50% of the nation's total energy consumption, with electric motors being the largest consumers of electricity, estimated to represent 60–70% of the total power usage in factories. Consequently, improving the energy efficiency of motor systems plays a critical role in the national strategy for energy conservation, greenhouse gas emission reduction, and sustainable development.

Alongside advancements in science and technology, advanced technical solutions such as high-efficiency motors (IE3, IE4, IE5), variable frequency drives (VFD), vector control, predictive maintenance, and drive system optimization have been widely adopted globally, delivering energy savings of 10% to 30% depending on the load type. However, in Vietnam, a majority of industrial motors remain standard or medium efficiency models (IE1–IE2), are not equipped with speed control, or operate under non-optimal conditions. This indicates significant potential for improving energy efficiency in this sector.

The “Energy Efficiency Technology Catalogue – Electric Motors” has been compiled to provide enterprises, technical specialists, and energy managers with an in-depth, up-to-date, and practical reference. The document presents an overview of electric motor technology, latest development trends, feasible energysaving technical solutions, guidance for equipment assessment and selection, along with domestic and international case studies. The content scope of this catalogue focuses on electric motors with a rated power of 15 kW and above. This group of motors is commonly used in industrial drive systems and significantly impacts an enterprise's total electricity consumption. Very low-power motors for domestic appliances or specialized applications are outside the scope of this document.
