德国铁路为提高现有以及今后动车的功率,研究了轮轨系统中使用直线电动机技术的可能性。首要的问题是,用直线电动机产生的附加切向力提高牵引力。接着的另一个项目是,研究直线电动机产生的附加法向力分量是否能提高传递到轮轨接触点上的牵引力或制动力,以及是否能降低轻型导向的端部控制车对侧风的敏感性。 German Railways In order to improve the current and future power car, the possibility of using linear motor technology in wheel-rail systems was studied. The primary problem is that the additional tangential force generated by the linear motor increases traction. Another project followed was to investigate whether the additional normal force components generated by the linear motor can increase the traction or braking force transmitted to the wheel and rail contact points and reduce the sensitivity of the light steering end control car to crosswinds .
