Apparatus for damping oscillations in a linear motor comprising an excitation winding and a traveling field winding supplied from a fixed a-c system in which means are provided for generating a transversal field in the air gap of the synchronous linear motor, with the generating means controlled by a control means providing an adjustable current thereto in response to a control signal supplied from a control device having as an input the output of measuring means developing a signal proportional to the oscillations in the propulsion vehicle drive. |
