Abstract Disclosure is made of a traction means with electrodynamic suspension of aehicle, intended for high-speed land transport and comprising a synchronous linear motor whose exciting winding is mounted on the vehicle and at the same time serves as the exciting winding for electrodynamic suspension of the vehicle, whereas the three-phase armature winding of said synchronous linear motor extends horizontally along the track and is a single-layer winding with one turn for the pole and phase. In the active area, the conductors of the armature winding are made as strips parallel to the track plane and having a width up to one third of the pole pitch. The exciting winding induces eddy currents in said strips on the side of the vehicle, which eddy currents ensure electrodynamic suspension of the vehicle. Traction means of this type can be used in the future in high-speed urban and suburban transport.
