Superconducting Electrodynamic Suspension Technology

Magnetic Levitation Principle

Stable levitation is achieved through electromagnetic forces generated by relative motion between onboard superconducting magnets and ground-based suspension coils. This EDS technology represents a major advancement over conventional magnetic levitation systems.

Innovative Propulsion System

Propulsion operates via interaction between the induction field created by onboard magnets and the traveling wave magnetic field generated by ground-based traction coils. This system ensures smooth and efficient propulsion at very high speeds.

Levitation Activation

At 150km/h, onboard magnets induce currents in ground-based suspension coils through electromagnetic induction, generating coupling force. The vertical component of this induced force lifts the train, while the horizontal component provides propulsion through differential repulsion.

Superior Levitation Gap

Superconducting EDS technology offers considerably expanded levitation range. The CRRC Changchun vehicle achieves substantial 100mm levitation gap and 70mm guidance gap, contributing to its high-speed capability.

Revolutionary Safety and Reliability

Secure Guideway Design

The maglev vehicle operates on a U-shaped semi-enclosed guideway. CRRC asserts this design effectively eliminates vehicle derailment risk.

Self-Stabilizing System

It incorporates a self-stabilizing levitation system that eliminates the need for active control, crucial for ensuring reliability at high speeds. This innovation significantly reduces operational complexity.

Power Failure Safety

Superconducting magnets remain operational for more than one hour during power failure, enhancing safety and operational continuity.

Advanced Technical Innovations

Specialized Levitation Bogie

A specially developed levitation bogie constitutes a key innovation, enabling rubber wheel contact at low speeds for ground operations and levitation guidance during high-speed operation.

Magnetic and Cooling System

The vehicle integrates a high-temperature superconducting (HTS) magnet and low-energy cryogenic cooling system, both developed by CRRC.

Advanced Braking System

A sophisticated braking system integrates primary electric and supplementary hydraulic systems to achieve required average deceleration performance of -1m/s².

Testing and Future Plans

Current Test Track

A 200-meter test track is currently under construction at the CRRC Changchun plant, with completion expected by year-end.

This track will serve to verify the prototype's design and enable CRRC Changchun to implement necessary modifications to the propulsion system and bogies.

Future Testing

To conduct full levitation tests, a longer track will be required. No confirmed plans have been announced regarding longer track construction.
