TozoniMAGLEV is a self-regulating system for high-speed, ground transportation, based on permanent magnets and steel rails, and is designed for magnetic levitation, stabilization, and propulsion of vehicles moving at high speed.

TozoniMAGLEV is essentially a new type of MAGLEV, using permanent magnets as sources of magnetic fields and laminated carbon steel cores for rails. TozoniMAGLEV is based on a new principle involving the interaction between permanent magnets and steel cores. Permanent magnets are rigidly assembled and installed on a train, and steel cores are a part of the track. This is the most efficient way of electromagnetic interaction. 

The most important peculiarity of TozoniMAGLEV is its self-regulation. For the first time ever, a system possessing a minimum of potential energy at its neutral levitation position has been created. This means that, during the vehicle flight, it reacts instantaneously and flawlessly to any shift of the vehicle from its trajectory and to any deviation from its given speed by producing internal stabilizing forces, returning the vehicle back and changing its speed to assigned value.

As any prototype of Maglev, TozoniMAGLEV comprises three parts: suspension, linear motor, and power system. But these systems are different in principle. Amlev subsystems are :
  • Magneto-dynamic levitation and stabilizing self-regulating system - MDS
  • Linear synchronous motor based on permanent magnets - PMLM
  • Conventional power system that uses constant frequency  of 50Hz. 
The Magneto-Dynamic System and and Linear Synchronous Motor are both comprised of permanent magnets and steel cores, and are functionally connected and interacting with each other.

The Magneto-Dynamic System provides levitation and stabilization of a vehicle suspended in a magnetic field produced by its own permanent magnets. The Linear Synchronous Motor produces the propulsion force, providing the assigned velocity of the vehicle along a preliminary designated trajectory of the guideway. The vehice velocity is determined by the interaction of the magnetic field of the vehicle magnets with a current traveling wave in the stator winding powered by the current of constant 50Hz frequency.

Each of said subsystems is comprised of two main parts: 
  1. Fixed part - guideway/stator (which is common for both subsystems ) including extended steel core rails of the Magneto-Dynamic System, and extended three-phase windings of the Linear Synchronous Motor
  2. Moving part - permanent magnets of the levitator of the Magneto-Dynamic System, and permanent magnets with the steel cores of the rotor of the Linear Synchronous Motor – all affixed to the moving vehicle. 
Each of the subsystems is self-regulating and operates without fast response servo control. Self-regulation is defined as coordinated interaction between mechanical and electro-magnetic processes within the structures of both subsystems.

It is possible to design a small rotation model for measuring destabilizing forces impacting a flying vehicle at its shifts from an assigned trajectory, which allows to eliminate the full-scale modeling stage when designing the TozoniMAGLEV system. 

The different applications of TozoniMAGLEV, such as a simplified version of TozoniMAGLEV and a Gas-Gun accelerator based on MDS for a repeated launch of heavy objects into space, are also presented.
