Hyosung produces all types of motors, ranging from low-voltage small motors to ultra-high voltage large scale motors, playing a key role in domestic industry. With the capacity to produce a 20,000 horsepower motor and automatic production lines, Hyosung produces more than 40,000 motors per month and supplies them to domestic and overseas customers who recognize outstanding quality. We will provide advanced products which are lighter and more efficient. This product ensures high compatibility by adopting KS and international standards (IEC, NEMA) and is available in a variety of types - totally enclosed, semi-enclosed and class F, H and C insulation types. The use of computers in designing electromagnetic circuits, CAD/CAM-based structure design and precision machinery, ensure high reliability. This product is available for various purposes, in such areas as general industry, steel industry, power plants and ships, satisfying KS and international standards. Its features include an excellent insulation system, special squirrel-cage rotor structure, low-vibration and low noise design. This product is a combination of an induction machine and permanent magnet motor which functions as an induction machine upon starting, and as a synchronous machine during operation, providing higher efficiency and power than a high efficiency motor. This compact and lightweight product adopts a high performance SmCo-based permanent magnet, and uses the coils and insulator to endure a high temperature of 180'C. Its exterior is made of aluminum alloy to endure vibration and shock, and it adopts the MIL standard to select the parts that satisfy military specifications. Optimum design of core and windings and use of premium materials reduce loss by 20-30%, and the margin in temperature increase extended the life of a motor. The change of the external fan's shape and structure have reduced the turbulence and electromagnetic noise, resulting in a noise decrease of 3-8dB compared to a standard motor. Most of the capacity types and dimensions are consistent with those of standard motors, and this ensures the compatibility of the product. Motor driven by direct current, the DC motor provides high speed variability and precision, so it is generally used as a driving motor in the speed-variable continuous process for steel and extrusion machines, steel wire and power cable machines. The stator, main pole and interpole were designed to have a complete lamination structure of an all-in-one type, so it is very mechanically strong. This product adopts various cooling types and protection classes. This generator can provide a primary and secondary power source to various industrial facilities including factories, buildings, large apartments and ships. The adoption of an excellent insulation system has greatly increased product life, and its automatic voltage regulator using a thyristor provides superior voltage features. Based on the expertise and technology accumulated while producing motors for over 40 years, we provide various technical services regarding prevention and maintenance, not only for Hyosung products, but also for other products. A special vehicle equipped with high voltage motor diagnosis system enables speedy and accurate diagnosis, and the diagnosis data are saved in a DB to maximize the reliability and efficiency of customer facilities. The casting business of Hyosung realized standardization in such products as motor frames, brackets, terminal boxes and covers, and it is developing a firm reputation in diverse areas, such as, reducers, pumps, circuit breakers and other various industrial parts.
