According to research conducted by the Ministry of Economic Affairs' Bureau of Energy, power consumed by motor equipment and applications account for over 50% of overall electrical power consumption. In addition, industrial motor equipment and applications account for over 70% of industrial electrical power consumption. This is why the development of motor products towards energy conservation has become a sure trend. In light of this, Tatung has developed the IE3 premium-efficiency motor.
It is often said that "motor is the mother of machinery, while machinery is the mother of industry." since motors are the core part of various types of power machinery. As early as 1949 Tatung already understood the importance of motors, which is why Tatung introduced related technologies from Westinghouse of the United States and Toshiba of Japan to establish its own development capabilities in this area. In 1974, Tatung commenced operation of its factory in Sanhsia and began producing motor products using automated equipment.
Today, Tatung's Sanhsia factory produces a wide range of motors, with horsepower ranging from 1/4HP to 30,000HP. The types of motors produced by Tatung include single-phase motors, three-phase motors, high voltage motors, low-pressure motors, generators, high-efficiency motors, explosion-proof motors, gear motors and speed variators, variable-frequency drive motors, elevator motors, pump motors, as well as many other types of special motors for specific applications.
It is also worth mentioning that Tatung was the first motor manufacturer in Taiwan to obtain the CNS mark and has also obtained various other certifications: NEMA and UL in the United States; T MARK and JIS in Japan; CSA in Canada; the CE MARK in the European Union; GB in China; ISO-9001, ISO-14001, and OHSAS 18001-2007. In 2010, Tatung even launched the world's first motor product with carbon footprint verification, which has helped it solidify its foundation in the global market.
In summary, Tatung has been developing motors for over 60 years, and its products are sold in virtually every corner of the world. Tatung also has many plans for developing motors for overseas markets going forward.
According to Book Kuo, Vice Director of the Domestic Sales Division of Tatung's Motor Business Unit, "Ever since Tatung first started engaging in the motor business, efficiency has been one of its focal points. Tatung has always worked to use less material to produce higher horsepower. Today, due to trends towards energy conservation as well as carbon reduction, virtually every country is stressing the ability of motors and systems to conserve energy. This is a testament to the value of the IE3 motor or even the permanent magnet servo motor. Permanent magnet servo motors which use servo system for control are different from variable- frequency drive motors that use inverters as their basis for control. Permanent magnet servo motors have higher accuracy in terms of control and therefore are more capable of increasing efficiency in terms of energy conservation."
Years of R&D has laid the foundation for the development of high-efficiency motors
Back when competitors were still focusing on IE1+, Tatung was already conducting R&D on IE3 premium-efficiency motors. In the early stages of IE3 development, Tatung was alone at the cutting edge and faced many obstacles, but it was able to overcome those obstacles. Now, countries including the United States and Japan, are making the use of IE3 motors mandatory due to energy conservation requirements. Tatung's line of IE3 products, including products that comply with or even exceed CNS14000 (version 2012) standards are fully ready to meet the needs of this unstoppable trend.
Tatung's IE3 motor products have four primary characteristics, says Book Kuo. Firstly, they are "highly efficient," not only reducing process loss, but also decreasing copper and iron loss due to the use of high quality silicon steel. Secondly, they are "low magnetic flux," suppressing temperature rise as well as reducing loss by reducing magnetic flux densities. Thirdly, they have "high air volume and low-loss fans," which increase heat dissipation and reduce mechanical loss. Finally, they have "new configuration," meeting requirements concerning high strength, minimal temperature rise, and low vibration by increasing the heat-dissipation surface area and reinforcing the motor frame.
In addition to high-efficiency motors, Tatung is also one of the few vendors that possess the ability to produce custom-made large high voltage motors. Kuo also says that although the horsepower range is usually between 1/4HP to 30,000HP, Tatung is capable of producing specific large motors for all kinds of operations, including desalination plants, large cement plants, and big fans and blowers applications, with even higher load requirement.
There are a number of reasons why Tatung has been able to successfully develop such products. It is able to take advantage of CAE analysis in its R&D and design efforts to produce high-efficiency, high power factor, and high horsepower products, as well as products with long lifetime and optimized bearing strength structures. Furthermore, Tatung also has the largest vacuum pressure impregnation (VPI) system, which can prevent coronas at high voltages and ensure a long product life for the motor.
Also, the trend towards low carbon emission and zero pollution has fueled the popularity of electric vehicles. Tatung has teamed up with research institutions (including ITRI and the Metal Industries Research & Development Center) and many vehicle manufacturers to develop EV motors. Products developed include motors for forklifts, dune buggies, pickup trucks, electric yachts, and electric buses. These products are already in production and available on the market, and there have already been orders for them.
According to Kuo, Tatung's motor business is based in Taiwan and is actively promoting its visibility globally by participating in trade shows and exhibitions. Tatung has established operations with local partners in Thailand, Malaysia, Canada, and Europe, and has established branches in Singapore, Japan, and the United States to expand its business. Tatung has also established strategic alliances with maintenance plants in India in order to expand its post-sales services there and is actively pursuing related certifications in the Middle East. Furthermore, Tatung is also planning to establish sales locations in Saudi Arabia in hopes that the products of its successful R&D efforts can be exported overseas so that they can be enjoyed by people all over the world.
