The technical scheme of China's first permanent magnet direct drive electric locomotive has passed expert review

Zhongche datong electric locomotive co., LTD., which developed China's first permanent magnet direct drive electric locomotive technology, has passed the expert review, the company announced Thursday. This is an important achievement in the research and development of high-power ac drive electric locomotives in China.

According to the introduction, permanent magnet direct drive is the most advanced driving technology at present, and also the industry recognized next generation driving technology. In recent years, zhongche datong company has actively promoted the research and development of new products, accelerated the research and development of high-end electric locomotive products, and won the recognition of the European market.

Previously, the china-white freight 1 and china-white freight 2 locomotives developed by CRRC datong company for belarus have been running steadily. With the aforementioned high-end rail transit products, belarus is able to carry out transnational joint transportation missions in a number of countries, such as Russia and Lithuania, effectively consolidating its position as a transport hub in the Eurasian continental bridge.

Car BiSiCong datong company related chief, said in a few days ago, by the China railway corporation, southwest jiaotong university and other units of evaluation experts agree that car in datong company development with permanent magnet direct drive system of electric locomotive main technical indicators innovative and technological advantages, the system performance is excellent, agree through design review.

According to bi sicong, permanent magnet direct drive technology is characterized by remarkable energy saving and environmental protection, which is widely used in wind power generation, oil exploitation and geological exploration. This permanent magnet direct drive technology is first applied in high-power ac drive electric locomotive, which will effectively promote the "upgrade" of the overall performance of China ac drive electric locomotive.

It is understood that China's first permanent magnet direct drive electric locomotive developed by China railway locomotive datong company will be offline within this year. The locomotive is equipped with 1200KW permanent magnet motor. Compared with other ac electric locomotives of the same power, this type of locomotive can save about 200 degrees of power per hour. Because the locomotive driving system adopts direct drive mode, the structure is simple, which can effectively reduce the loss of mechanical energy consumption and improve product reliability.
