MAGNETIC LEVITATION TRANSPORT SYSTEM (LIRO) 
Invention Overview: 
The invention relates to a magnetic levitation transport system, specifically a system 
comprising a movable element in magnetic levitation. It also describes a method for 
moving this element using the system. This technology is applicable in various fields 
such as industrial transport and precision guidance systems. 
Field: 
The patent pertains to the field of magnetic levitation transport systems, specifically 
focusing on systems comprising movable elements in magnetic levitation for use in 
various applications including elevators, industrial transport, and precision guidance 
systems. 
Problem: 
The primary problem addressed by the patent is the complexity, high cost, and 
maintenance challenges associated with existing magnetic levitation systems and 
rotary-linear transmission technologies. These systems often require continuous power 
supply, experience mechanical wear, and need complex infrastructure for operation. 
Technical Problem Solved: 
The invention addresses the need for a transport system that is simple in design, has low 
manufacturing and operating costs, and allows efficient and accurate movement of the 
movable element. 
Solution: 
The patent proposes a transport system utilizing permanent magnets to achieve 
magnetic levitation and movement without the need for external power sources for 
generating magnetic fields. The system comprises: - A rotatable shaft supported by bearings in a supporting frame. - A series of identical permanent driving magnets fixed to the shaft, each with magnetic 
poles phase-shifted by 120° relative to neighboring magnets. 
- At least one set of three permanent propulsion magnets configured as plates with 
coplanar flat surfaces facing the shaft, arranged in an N-S, N-S, N-S sequence along the 
shaft’s longitudinal axis. - A movable element fixed to the set of propulsion magnets and guided by two parallel 
guide rails with grooves. Permanent guide magnets are fixed on the extremities of the 
movable element and within the grooves, creating a repulsive magnetic interaction to 
maintain levitation. 
The system enables the movement of the movable element along the shaft’s 
longitudinal axis through the interaction of the rotating magnetic fields generated by the 
driving magnets and the static magnetic fields of the propulsion magnets. 
Applications: - Extraction of fluids (e.g., water or crude oil) from great depths and bringing them to the 
surface. - Vertical movement of an elevator (residential or industrial). - Horizontal movement of various loads (e.g., objects, goods, people, animals). 
Key Components: 
1. Shaft supported on bearings within a supporting frame, capable of rotating about a 
longitudinal symmetry axis. 
2. Permanent driving magnets fixed to the shaft, spaced equally, with magnetic poles 
axis phase-shifted by ±120° relative to neighboring magnets. 
3. Set of three identical permanent propulsion magnets configured as plates, arranged 
coplanar and at a specific distance from the driving magnets. 
4. Movable element with two profiled extremities, fixed to the propulsion magnets, 
arranged in alignment with the shaft. 
5. Two guide rails with grooves accommodating the extremities of the movable element, 
using guide magnets for magnetic repulsion and levitation. 
Preferred Embodiments: 
- Driving magnets can have an annular or prismatic bar shape, fixed either on the 
exterior or inside the shaft. - Keepers are used to guide and amplify the magnetic fields generated by the driving 
magnets towards the movable element. - The system may include a second assembly of keepers and a closed loop conveyor belt 
with propulsion magnets. 
Method of Operation: 
1. Positioning the movable element in an initial position. 
2. Rotating the shaft to cause the movement of the movable element along the 
longitudinal axis. 
3. Halting the rotation to stop the movement at the desired position. 
Advantages: 
The key advantages of the proposed system include: - Elimination of the need for external power sources to generate magnetic fields, relying 
solely on permanent magnets. - Reduced operating and maintenance costs due to the lack of mechanical wear and the 
simplicity of the design. - Efficient and accurate movement of the movable element facilitated by the phase
shifted magnetic fields and permanent guide magnets. 
Novelty: 
The patent introduces a novel configuration of magnetic levitation transport systems 
using phase-shifted permanent magnets and guide magnets to achieve movement and 
levitation without external power sources. The use of a 120° phase shift in the magnetic 
poles of the driving magnets and the specific arrangement of propulsion and guide 
magnets presents a unique solution not found in prior art. Given the detailed 
configuration and the absence of similar systems in publicly available knowledge, this 
invention is considered novel. 
Inventive Step: 
The inventive step lies in the specific arrangement and interaction of the phase-shifted 
driving magnets and the propulsion magnets, as well as the use of guide magnets for 
maintaining levitation. This configuration is not an obvious solution to someone skilled 
in the art, given the traditional reliance on continuous power supplies and more complex 
systems in existing magnetic levitation technologies. The invention's simplicity, cost
effectiveness, and reliance on permanent magnets provide a significant advancement 
over known solutions.
