. In linear traction drives of high speed vehicles moving with velocities about 350 – 450 km/h it is expedient to use synchronous motors with stator winding located on track structure and constant magnetic field sources (permanent magnets, superconducting windings or bulk superconductors) located on the vehicle. Such high speed traction system does not require the moving contact for its power supply and it means a considerable advantage of system. Lack of a moving contact on the vehicle involves also the use of contactless system for auxiliary power supply. Purpose. The purpose of the paper is to analyze the versions of contactless auxiliary energy consumers power supply of high speed maglev vehicles with synchronous traction motors. Method. Weight, size and energy parameters of maglev vehicles power supply sources for auxiliary consumers are discussed and their areas of use are analyzed. Results. For contactless power supply of auxiliary energy consumers of maglev vehicles with electrodynamic suspension it is expedient to use linear induction generators and rechargeable batteries. For maglev vehicles with electromagnetic suspension it is expedient to use linear generators, linear transformers and rechargeable batteries. Practical significance. Results may be used for creation of national commercial high speed maglev transport. Conclusion. The choice of combination of power supply sources for auxiliary consumers is determined by vehicle magnetic suspension type. For vehicles with electromagnetic suspension it is expedient to use linear transformers, linear induction generators and rechargeable batteries. For vehicles with electrodynamic suspension use superconducting magnetic systems it is expedient to use linear generators and rechargeable batteries.
