ABB's energy efficiency is close to 100%, setting a world record
Zurich, Switzerland, July 5, 2017 – The ABB 6-pole synchronous motor with a power of 44 MW was measured at a factory efficiency of 0.25% higher than the contracted 98.8%, setting a world record for motor efficiency. This efficiency increase saves approximately $500,000 in electricity bills per motor for up to 20 years.
Sami Atiya, president of ABB's Robotics and Motion Control Division, said: "At present, electricity bills are still the largest component of the total cost of ownership of synchronous motors. Therefore, saving electricity costs will have a significant impact on profits. In addition to extremely high energy efficiency, ABB Synchronous motors are also known for their proven quality and reliability. The rugged design ensures reliability in low temperature and low vibration conditions. As a pioneering technology leader in the energy revolution, as a new phase strategy Components, we will always be firmly committed to developing technologies for efficiency and productivity."
Based on ABB's extensive industry experience and more than 100 years of motor manufacturing experience, ABB achieves record efficiency by optimizing the electrical and mechanical properties of the motor. The average efficiency of this type of synchronous motor is 98.2% to 98.8%. If the motor is running continuously, a 0.25% efficiency increase will save 1 million kWh per year, which is equivalent to the annual electricity consumption of 240 European households.
Today, the world's energy needs are almost double that of 30 years ago. According to the International Energy Agency, energy demand is likely to increase by more than 50% by 2030. To meet this challenge, it is not only necessary to introduce new energy sources, but also to make more efficient use of existing energy sources. The industrial sector has enormous potential for energy savings, from motor-driven applications to the use of frequency converters and high-efficiency motors to reduce energy consumption and reduce losses, often helping to reduce energy usage by 20% to 50%.
Motor efficiency is the ratio of the mechanical power output divided by the electrical power input. The world-record ABB synchronous motor is ultra-efficient in the factory test that customers have witnessed, and will be installed on an air separation unit that produces industrial gases to drive the compressor. This synchronous motor is a special type of AC motor with a size of approximately 5 m x 4 m x 4 m and an output of 44 MW. Typical applications for synchronous motors are fans, pumps, mills, mine hoists and compressors in the air separation, oil and gas, chemical, marine, metallurgical, mining, water and wastewater, and pulp and paper industries.
