铁道车辆牵引电动机的技术动向

通过对铁道车辆用牵引电机功率电子技术等的革新,实现了小型、轻量、高功率化。并且,替代直流电机的感应电机,已广泛用于电动车（地面上）、通勤电动车直至新干线车辆、机车等所有铁道车辆上,成为技术成熟的牵引动力系统。今后,感应电机仍将属于主流牵引电机。而近年来,对新一代牵引电机提出了更高要求,如高速化（电机的小型、轻量、高功率...

Technical trend of traction motors for railcars

With the help of power electronic techniques,traction motors for railcars have realized compact design,light weight and high power.As an alternative to DC motor,induction motors have found wide applications in mass transit vehicles,commuter cars and Shinkansen locomotive and vehicles,and have become a technically mature traction power system.Over the past few years,stricter requirements have been made of the new generation of traction motors,such as high speed(small in size,light in weighthigh efficiency), ...
