China South Locomotive Zhuzhou Electric Co., Ltd. and the national key institutions jointly developed by Zhejiang University, included in the national 863 plan "high-speed railway major key technology and equipment development of key projects", with completely independent intellectual property rights TQ-600 permanent magnet synchronous traction Motor, in the company's national testing station successfully passed the test to verify, with good "anti-demagnetization" capacity, the performance indicators to meet the design requirements, becoming the first through the national verification of high-speed rail permanent magnet traction motor The
It is understood that the permanent magnet synchronous traction motor will be the first in early 2014 has been equipped with a large number of service 350km / h high-speed rail, to further improve China's high-speed rail in energy saving, emission reduction, safety, comfort and other competitive advantages, marking the Chinese high-speed rail has been broken International technology monopoly, successfully entered the era of permanent magnet drive.
The company in charge of the designer He Yunfeng introduction, permanent magnet traction motor with power density, power conversion efficiency, overload protection and other advantages, and permanent magnet loss is plagued by its popular application of the world problems. TQ-600 permanent magnet synchronous traction motor using the world's new rare earth permanent magnetic materials, the coercivity of up to 381h, good magnet stability, anti-demagnetization ability. When the test temperature reaches 180 ℃, the permanent magnet irreversible loss is less than 5%. Through the finite element simulation analysis, the permanent magnet fully meet the requirements of anti-demagnetization of the motor. In all operating conditions, the permanent magnet will not produce demagnetization phenomenon, to ensure the reliability of the motor performance.
It is understood that a row of 8 high-speed rail with TQ-600-type permanent magnet motor drive, compared to the current 365kW AC motor, a single motor power increased by 65% to 600KW, the maximum power of 635kW, the total number of motor can be reduced from 24 to 13 units. Single motor power density increased 31.5%, weight reduction of 1/3, the total weight of the motor vehicle to reduce 3165kg, equivalent to more than 50 adult weight, reached the international advanced level, which China's high-speed rail further energy saving is of great significance
According to reports, the motor insulation performance, ventilation structure, etc. are also in the international leading position. The insulation technology combines the advantages of high-power locomotives and high-speed traction motor insulation structures, with higher insulation reliability; the use of a new closed ventilation design to ensure that the motor internal cooling system clean and clean.
