Direct Current Motors Series Z2-900 Large-size

The Z2-900 series electrical machinery which is developed and designed by our company independently is a main-drive direct current motor specially used for the metallurgy,the mine and the petroleum. This series electrical machinery's main feature is the electrical machinery have solid multi-angular laminate frame, box end shield, end shield rolling bearing, type of cooling of the motors of this series is IC37 or IC86W. Its advantage is covering a smaller area, costing less money, lower noises and convenient for maintenance. Compared with the same type of ZD series electrical machinery, its single weight is lighter than the ZD series'by about 30%, compared with the same type of import machinery,its price is only 1/3 of the import machinery, and has the extensive market prospect. The design and the manufacture of this series electrical machinery are base on absorbing the advanced technology of Siemens,ABB Company .Thus, the electromagnetism parameters and mechanism parameters of this series electrical machinery are in the domestic advanced standard, and achieve the international advanced level.This article introduced the Z2-900 direct current motor's spectrum design in detail, the standardization design, the universalized design, the analysis confirmation of the fibre tape fastened structure of armature winding, fibre tape performance test ,electrical machinery's insulation structure and the characteristic, the equalizer structure and the computation, electrical machinery's interior and exterior spare part structure, the tentative data confirmation and the electromagnetism computation and the design of computer program for retrieval. And unifies the present situation, has carried on the simple analysis to market prospect. Along with the fast development of mining of our country steel industry, the Z2-900 direct current motor must be developed swiftly.
