TZYW/TAW series positive pressure shell type/increased safety type brushless excitation synchronous motor is an innovative product developed by Jiamusi Motor Co., Ltd. according to the technical standards of explosion-proof motor industry and product development trend. The innovation and frontier of explosion-proof technology application of the product has been verified through the international scope of novelty examination. In 2013, it passed the new product appraisal organized by the Industry and Information Technology Commission and obtained the first product (set) honorary certificate and the national key new product certificate. The motors of this series of products not only retain the advantages of the increased safety motor, such as no spark, arc and dangerous temperature, TE time protection, etc. At the same time, it has the advantages of positive pressure shell type explosion-proof motor safety, and the standby motor can take off at any time when it is under pressure holding state. It has the characteristics of beautiful appearance, small vibration, low noise, high protection level, convenient operation and maintenance, high safety and reliability. Widely used in petroleum, petrochemical, chemical, fertilizer, coal, natural gas and other industries, working in the "2" zone of explosive gas environment, driving reciprocating compressor and other large mechanical equipment. The TZYW/ TAW10000KW-20P explosion-proof synchronous motor produced for CNOOC's Huizhou Refining & Chemical Phase II Project in 2016 is the largest positive pressure enclosure/increased safety brushless excitation synchronous motor in China.
