High-efficiency motors: "Haze Killers”

  • Emissions from burning coal are a major cause of air pollution
  • The amount of electricity saved each year by an ABB 12kW high-efficiency motor could power 12 households in Beijing

  • In China's primary energy structure, coal occupied a share of nearly 66% in 2013. More than half of the country’s total coal consumption is used for by the power industry; and large amounts of soot, sulfur dioxide and nitrogen oxide emissions from burning coal have become an important cause of haze1. Effectively reducing electricity consumption indirectly results in lowering coal consumption—“saved energy is the greenest energy.”

    High-efficiency motors are one of the most effective ways to save electricity. According to statistics, motors account for two-thirds of the world's industrial electricity consumption, equivalent to 28% of the world's total electricity consumption; but in China, the ratio is as high as over 50%. If the efficiency of all electric motor systems nationwide increases by 1%, the amount of electricity saved this way over a year is enough to power 9.2 million Chinese households2. Promoting the use of high-efficiency motors should become an important part of China's economic transformation, contributing to energy saving and the reduction of emissions and haze.

    As a leader in the global electric motor industry, ABB has long been committed to promoting the application of high-efficiency motors in China. In 2007, ABB took the lead in launching the high-efficiency motor M3BP in the Chinese market. Later in 2011, ABB launched the M2BA series high-efficiency motors in the Chinese market as well as the efficient aluminum-shelled motor in 2013. In 2014, ABB will launch a high-efficiency, explosion-resistant motor and the IE3 super-efficient motor, further expanding its motor product line to meet the fast-growing market demand for high-efficiency motors in China.

    Compared with an ordinary motor of the same power, a high-efficiency ABB 11kW motor improves energy efficiency by 2% and can save 33,600 kWh electricity a year, equivalent to the annual electricity consumption of 12 households. In 2013 alone, high-efficiency motors provided by ABB in the Chinese market helped customers save 410 million kWh electricity—equivalent to the annual electricity consumption of 142,000 households3 —and reduce carbon dioxide emissions by approximately 400,000 metric tons.

    In early 2014, ABB launched its first low-voltage motor designed specifically for the Chinese market—the M2BAX. The product was mainly designed by the Chinese development team and was debuted in China as well. It is in line with the international IE2 high-efficiency standard of the IEC as well as China’s Level 3 energy efficiency standard (GB18613-2012).

    Using the high-efficiency M2BAX motor, customers can not only effectively save power and improve efficiency, but of the cost recovery time of the M2BAX is only 3-6 months—much higher than ordinary motors. IEA report data shows that electricity cost is undoubtedly the “main driver” of operating costs throughout the entire life cycle of a motor, accounting for an average of more than 95%. The excellent energy-saving effects of using high-efficiency motors can help customers recover investment costs within a reasonable time frame. They also benefit from its long-term low-energy-consumption.

    As a general-purpose high-performance low-voltage three-phase AC induction motor, M2BAX has a wide range of applications in many areas, including water treatment, HVAC, food and beverage, textile machinery, machine tools and other industries. With its excellent stability, M2BAX can significantly reduce the unplanned downtime of the production line normally caused by the failures of ordinary electric motors.

    Wu Yuhui, head of ABB Motors and Generators in China, says: "ABB has more than 100 years of experience in motor manufacturing as well as an industry-leading product design concept. It can supply electric motors to the vast majority of industrial areas. In the future, based on China’s national energy planning, ABB will develop more efficient electric motor products and solutions to meet the Chinese market demand. "

    ABB (www.abb.com) is a leader in power and automation technologies that enable utility and industry customers to improve their performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 150,000 people. ABB has a full range of business activities in China, including R&D, manufacturing, sales and services, with 19,000 employees, 37 local companies, and an extensive sales and service network across 109 cities.
