Domestic first rare earth permanent magnet subway passengers operate

  The reporter learns from electric car era: changsha city rail transit line 1 permanent magnet traction system has passed before the passenger review, China's first listed "metro" rare earth permanent magnet has been in changsha metro line 1 in passenger service.

  According to the introduction, changsha city rail transit line 1 rare earth permanent magnet traction system train is China's first line of the autonomous rare earth permanent magnet traction system of the subway train. In early 2015, the overall design of the rare earth permanent magnet traction system was completed. In March 2016, the train was officially put into trial operation. As of 7 July, the train has completed a total of 12,500 km of unfailure-free test runs.

  "Compared with ordinary subway trains, the biggest difference of the rare earth permanent magnet traction system is that it adopts a more efficient and energy-saving permanent magnet motor as the driving force, which helps to achieve green travel." Electric car era in the deputy general manager and chief engineer is to introduce, traction electric drive system is implemented in rail transit vehicles driving "heart" of the unit, its performance to some extent determines the dynamics of the rail transit vehicle quality, energy consumption and control performance, is one of the core system of rail transit vehicles. The energy consumption of traction system accounts for about 40% to 50% of total energy consumption of rail transit system. The latest test results show that the train of rare earth permanent magnet traction system can reduce the energy consumption by about 11.5 %. Considering the regenerative energy of the traction system, the comprehensive energy consumption of the permanent magnetic traction system can be reduced by about 30%.
