Abstract: A self-regulating magneto-dynamic system, utilizing steel core rails and permanent magnets as sources of magnetic field, provided for magnetic levitation, stabilization and propulsion in a high speed ground transportation vehicle moving with high speed without friction along a track having a predetermined trajectory, comprising of a self-regulating magneto-dynamic levitation and stabilizing system (MDLSS) provided for magnetic levitation and stabilization of the vehicle, and a permanent magnet linear synchronous motor (PMLSM) provided for stable propulsion of the vehicle. Both systems are situated on the same vehicle, interacting with each other only through electro-magnetic process, working synchronously, supporting each other's stability and self-regulation, where the stability of the MDLSS affects the functionality of the PMLSM, and the precise work of the PMLSM allows for more optimum design of the MDLSS.

Abstract: An Electromagnetic Levitation Catapult for preliminary acceleration of a heavy individual payload includes a Magnetodynamic Levitation and Stabilizing Self-Regulating System providing stable flight of the payload along a pre-determined trajectory, a rotor with changeable size of the pole pitch, a stator extended along the trajectory of flight and a synchronizing mechanism. The stator is divided into three distinct sections: a start section where the winding turns have the same length, an acceleration section where the length of the turns increases in the direction from the start section, and a deceleration section. The payload is supported by a chassis carrying the rotor, so that when the rotor engages the stator, a propulsion force is created and propulses the payload along the trajectory. The rotor includes immovable long magnets and short magnets capable of being moved in the vertical direction. The synchronizing mechanism co-ordinates the pole pitch of the rotor with the turn length of the stator winding.

Abstract: A Linear Synchronous Motor for a high-speed, ground transportation vehicle includes a linear extended guideway stator assembly containing two extended symmetrical three-phase stator windings supported on the guideway and a rotor installed on the vehicle chassis and having an even number of identical units. When the winding is powered by three-phase sinusoidal current of constant frequency, the traveling wave of the sinusoidal current arises and runs along the stator. By varying the length of the turns of the stator windings, the velocity of the traveling wave is variable on different sections of the guideway, which include acceleration section, constant velocity section and deceleration section. Each of the rotor units includes vertically magnetized permanent magnets and two "C"-shaped steel cores which close the magnetic lines through two parallel air gaps. The permanent magnets move downward and upward within the "C"-shaped steel cores.

Abstract: The proposed Magneto-Dynamic Levitation and Stabilizing Self-Regulating System (MDLSS) is designated for the stable flight of a heavy body along a given trajectory and can be employed for the magnetic levitation of vehicles and cars in high-speed ground transportation systems and for self-regulating magnetic bearings, various devices for ground acceleration, and also in the launching of space ships, missiles, and other technologies. The MDLSS system includes identical unique units connected rigidly with each other by non-magnetic ties and oriented relative to each other such that de-stabilizing forces created in one unit are compensated by stabilizing forces created in another unit once the equilibrium has been violated. Each of the units contains two extended steel cores (C-shaped in their cross-section), both lateral surfaces of which are covered by non-magnetic metallic screens, and a magnet assembly placed symmetrically in the air gap between the tips of the cores.
