Introduction: Hunan Special Motor Co., Ltd. is located in Nanzui Town, Yuanjiang City, near the scenic Dongting Lake. It is a professional manufacturer of special motors for lifting and metallurgy. It is a wholly-owned subsidiary of Hunan Wananda Group, and its predecessor is Hunan Motor Factory and Hunan Construction Machinery Factory. It was founded in the early 197s. ? The company covers an area of 782, square meters, including a production area of 2, square meters, a factory building area of 56, square meters, total assets of more than 85 million yuan, and more than 8 employees, including more than 2 professional and technical personnel. The company has workshops for casting, forging, mold manufacturing, welding, mechanical processing, electrical processing, paint dipping, heat treatment, cold working, machine assembly, etc. It is equipped with 129 sets of advanced equipment such as EDM, wire cutting, special machine tools for machining motor base and end cover, special keyway milling machine for motor, high-speed slot punching machine and VPI vacuum pressure paint dipping. It has measurement rooms for length, precision measurement, mechanics, electricity and thermal engineering, and is a national second-class measurement unit. It has laboratories for mechanical performance, electrical performance, motor type test and chemical analysis. ? Since the state approved the designated production of special motors for lifting metallurgy in the early 197s, the enterprise has been developing and growing continuously through multi-stage technical transformation. In 1993, the company entered the ranks of "the 5 largest electrical machinery and equipment manufacturers in China". After the technical transformation of medium-sized high-voltage and variable-frequency motors in 25-26, it has now formed an annual capacity of 3, kilowatts of special motors for lifting metallurgy. Companies adhere to the market-oriented, vigorously adjust the industrial product structure, actively develop new products, and constantly improve product adaptability. The company has been a member of Jiamusi Explosion-proof Motor Research Institute, Shanghai Motor Technology Research Institute, China Electrical Appliance Industry Association Small and Medium-sized Motor Branch and China Construction Machinery Industry Association. It has jointly developed various new motor products with high technical content, excellent performance and reliable quality with Hunan University, Xiangtan University, Jiamusi Explosion-proof Motor Research Institute, Changsha Construction Machinery Research Institute of the Ministry of Construction and other colleges and research institutes, and has become an internship base for graduate students in Hunan University and other institutions and a research, production and test base for new motor products. The special motor and electromagnetic coupling for tower crane of France Potan Company and the two-speed braking motor for tower crane of Germany Liebherr Company have been introduced and trial-produced, which has filled the domestic blank and become a substitute for imported products. The company's "pole-doubling and pole-changing winding scheme" won the national patent, and the YZRDW series eddy current braking two-speed wound motor developed by applying this patent was rated as "national new product in 1995". Technical conditions of variable frequency speed regulating three-phase asynchronous motor for lifting and metallurgy (GB/T21972.1-28), technical conditions of variable frequency speed regulating three-phase asynchronous motor for YGP series roller table (GB/T21969-28) and technical conditions of YZR3 series winding rotor three-phase asynchronous motor for lifting and metallurgy (GB/T21973-28) ? The company strives for survival by quality, expands the market by quality, and improves and perfects the quality management system in line with ISO91 international standards. In 1999, it passed the ISO91 international standard quality system certification, and in 23, it passed the ISO 91: 2 international standard quality management system certification. ? The company's main products are: YKS and YJK series medium-sized high-voltage motors, YZ, YZR, YZE, YZRE, YZRW, YZRC, YZRDW, YJZR2 series lifting metallurgical motors, YD, YDEJ, YZD and YZTD series multi-speed motors for tower crane, YGP, YP2, YZP series variable frequency motors and YPKK series medium-sized motors. The company has won high praise from users for its products with reliable quality and excellent performance and good after-sales service, and enjoys a high reputation among users. It has been selected by more than 2 iron and steel enterprises such as Shagang Group, Wuhan Iron and Steel Group, Baotou Steel Group, Jiugang Group, Taigang Group and Xinjiang Bayi Steel Plant, and dozens of cranes, tower cranes, winches, fans, pumps, railway loading and unloading, mines and hydraulic machinery enterprises as cooperative supporting manufacturers, and some products have been applied as supporting parts in the country. The products sell well in more than 2 provinces and cities except Taiwan Province and Tibet, and some of them are sold abroad with the main engine. In January 28, Wuhan Iron and Steel Group International Economic and Trade Corporation awarded the company the honorary title of "27 Excellent Supplier". YZR series motor, the company's fist product, won the title of "first-class product" in the product quality spot check of the national and provincial quality and technical supervision departments, and won the "Hunan Product Quality Award" in 2. It was once rated as "specially recommended product" by the former Ministry of Machinery and the State Bureau of Quality and Technical Supervision, and was rated as "Hunan Famous Brand Product" for four consecutive years from 2 to 29. In 27, the three-phase asynchronous motor was rated as a national customer satisfaction product by china association for quality. "Chishan" brand trademark was recognized as "Famous Trademark of Hunan Province" for two consecutive years in 24 and 27. In 26, the company was awarded as "Excellent Enterprise in Quality Management Group Activities" in Hunan Province, and in 27, it was awarded as "Double Excellent Position in the Industry" in the "27 Questionnaire Survey on Product Quality and Service Satisfaction of Hunan Users Concerned about the Industry" organized by China Quality Miles Market Research Center. In June, 28 and July, 29, he won the first prize of the activity achievement of the excellent quality management group of Hunan machinery industry and the first prize of the activity achievement of the excellent quality management group of national machinery industry. In July, 28, he won the title of "Top 1 Enterprises of Hunan Brand Reputation" from 1,3 declared enterprises in the first Hunan Brand Reputation Forum and the large-scale series of publicity and education activities of credit changing life, and became the first member of Hunan Brand Reputation Alliance.
