CSR's permanent subway operation exceeds 10,000 kilometers

It is reported that the Shenyang Metro Line 2 train carrying the CSR permanent magnet synchronous traction system has achieved safe passenger operation mileage of 10,000 kilometers and carried more than 500,000 passengers, realizing the first-time operation of the permanent magnet synchronous traction system. New breakthrough.

According to the experts of the CSR Zhuzhou Institute, compared with the traditional asynchronous traction motors, the permanent magnet synchronous traction motor has many advantages, such as stable speed, high efficiency, small size, light weight, low noise, high reliability, etc., and is more energy-efficient than asynchronous traction motors. Can reach more than 10%. Traction power transmission system is a “heart” unit that realizes electromechanical energy conversion in rail transit vehicle equipment. Its performance determines the power quality, energy consumption, and control characteristics of rail transit vehicles to some extent, and is the key to the energy-saving upgrade of rail transit vehicles. part.

The 600 kw permanent magnet synchronous motor developed by CSR Zhuzhou has high power density and strict volume restriction. It is the largest power in the domestic rail transit field and the first high-speed permanent magnet synchronous traction motor for high-speed EMUs. The overall technical level is leading domestically. The market prospect is very broad.

CSR Zhuzhou Institute took the lead in the basic research of permanent magnet synchronous traction system in 2003 and set up a professional research team to overcome the system matching technology, low inverter switching frequency and high difficulty of the intermediate circuit, as well as ventilation cooling structure and motor Quantitative and high-power permanent magnet motor manufacturing technology and other difficulties, and with professional manufacturing capabilities and advanced testing levels to achieve the transformation of technology, has become a model of high-tech achievements to achieve industrialization of one of the models. At present, the company is making every effort to break through the market. In the next phase, it will continue to deepen the development of urban rail transit market and continuously promote the industrialization of the company's permanent magnet synchronous traction system.
