Description

ABB DSSR122 4899001-NK power supply unit for DC input/DC output
ABB has used the NMI series of high-voltage modular motors in the sea fastening expansion irrigation and water lifting project. This series of motors was developed and listed by the local R&D team in 2014, and has been widely used in the water and sewage, power, conveyor and other industries. The flexible modular design can be customized according to customer needs, so that the overall performance of the system equipment can be optimized. In this reconstruction project, ABB’s technical team made a special design for the installation mode of NMI, which can fully fit the equipment assembly and maximize the installation space.

DSSR122 In terms of performance characteristics, NMI series high-voltage modular motor has four advantages:
Vertical scheme of high thrust bearing: angular contact ball bearing scheme, basic design, applicable to the situation where there is no additional axial thrust or only limited axial thrust. Spherical roller thrust bearing scheme, with a special design mechanism, is applicable to the occasion where the driven equipment will generate large axial thrust to the motor bearing.
High power density and compact structure: high power density effectively reduces the cost of ownership. The compact structure makes the motor lighter, requires less space for installation, and reduces the infrastructure investment for motor installation.
Standard design based on efficiency: based on GB 30254-2013, two sets of efficiency design, GBII (high efficiency) and GBIII (basic efficiency).
Multiple cooling modes: NMI has designed a variety of cooling modes: IC01/611/81W/06/616/666/86W, etc. to meet various demands under different working conditions.
It is reported that ABB NMI series high-voltage modular motors have been successfully applied in many large-scale water conservancy projects, such as Nanning Yongjiang Water Diversion Project, Yancheng New Water Source Area and Water Diversion Project, Yellow River East Diversion Project (Qingdao Yellow River Diversion Project), South to North Water Diversion Huinanzhuang Pump Station and St. Helena Water Conservancy Project, as a powerful tool to deal with the challenge of water shortage and efficient use of water resources, Highlighting ABB’s modular and customized motor capabilities and experience in large-scale water conservancy projects.
As Luo Hui, head of IEC low-voltage motor business unit in ABB Motion Control Business Unit in China, said, “ABB has always had great advantages in providing customized and customized motors. Based on the global product technology platform and the accumulated rich industrial application experience, we have summarized some customer application scenarios and needs in specific industries into optional configurations for customers to choose. This has greatly reduced the complexity of customers when purchasing motors. At the same time, due to ABB’s customized We have built an application capability that can be more suitable for complex scenarios to deliver customized demand motors. “
