Apparatus for damping oscillations in the propulsion direction in a magnetically suspended propulsion vehicle driven by a synchronous linear motor
摘要：
A track bound propulsion vehicle such as a magnetically suspended vehicle and driven by a synchronous linear motor having a stator supplied from a fixed ac network with the stator installed along the track as a travelling field winding has a correcting element furnishing an ac output voltage at the network frequency and also connected to the travelling field winding to superimpose a voltage thereon with the phase of the ac output voltage of the correcting element adjustable by means of a control signal receiving an input from means measuring a quantity proportional to oscillations in the propulsion direction for damping such oscillations.
摘要（中）：

具有磁悬浮车辆的轨道推进车辆由具有从固定交流网络供给的定子的同步线性电动机驱动，定子沿轨道安装作为行进励磁绕组，具有校正元件，该校正元件提供交流输出电压 网络频率，并且还连接到行星磁场绕组以在其上叠加校正元件的交流输出电压的相位的电压，借助于控制信号可以调节，控制信号通过测量与推进方向上的振荡成比例的量的装置 阻尼这种振荡。
