This invention introduces a compact magnetic levitation system utilizing a Halbach permanent magnet (PM) array wheel. The system operates without an external motor by harnessing alternating pole pieces of varying sizes and polarities within the Halbach rotor. This configuration enhances the magnetic field intensity inside the rotor, enabling self-propulsion and rotation. The design includes a stator and conducting plate to facilitate levitation and rotational movement. This innovative system aims to enhance efficiency and applicability in magnetic levitation applications where compactness and autonomous operation are desired.

Conventional designs of Electrodynamic Wheel (EDW) magnetic levitation system using a Halbach rotor has inefficiencies and complexities associated with it:
- External Motor Dependency increases space requirements, and introduces mechanical connections (like drive shafts or gear assemblies), which can lead to additional points of failure.
- Complexity of Design increases manufacturing costs and reduces reliability
- Self-Propulsion Without External Motor using the interaction between its magnetic configuration and the stator’s coils to induce rotational forces which reduces complexity, size, and potential points of failure in the system.
- Enhanced Magnetic Field Intensity due to Halbach rotor design increases the magnetic field intensity on one side, leading to stronger levitation forces and more efficient propulsion.
- Compact Design makes it suitable for applications where space is limited or where minimizing weight and size are critical factors.
- Improved Efficiency and Reliability by reducing energy losses associated with separate motor components, and having fewer moving parts and simplified construction.
- High-Speed Capability: strong magnetic fields and efficient force generation, makes it particularly suitable for high-speed operations like transportation systems.
- The Halbach rotor retainer was 3D printed in plastic and used readily available block-shaped magnets.
- The stator was taken from an existing outer rotor motor available in the market and rewound with suitable enamelled copper wire.
- The prototype achieved over 17% higher lift-to-magnet weight compared to conventional designs, indicating improved levitation performance.
