ELECTRODYNAMIC SUSPENSION SYSTEM Russian patent published in 2019 - IPC B60L13/10 B61B13/08 

FIELD: machine building.

SUBSTANCE: invention relates to magnetic suspensions for vehicles. System of electrodynamic suspension contains the crew and track in the form of a gutter. On the bottom of the crew are superconducting solenoids excitation system electrodynamic suspension. On the side walls of the crew are superconducting solenoids of the excitation system of a linear synchronous motor. Stator windings of a linear synchronous motor are located on the vertical walls of the gutter. Gutter track structures are located on the bottom of the trench; they are made at the cruising speed in the form of a multi-link track structure, and at the acceleration sites of the end stations as a discrete set of short-circuited coils. At the same time, in the bottom of the front part of the crew, facing the track, there are air inlets connected by means of blowing grooves made in the bottom of the crew with profiled spiral grooves on the bottom surface of the bottom.

EFFECT: technical result is to increase the value of the quality factor of levitation.
