Background: Linear motion devices for industrial machines and robots are expected to realize their high efficiency drive and simple structure. Usually, a feed screw mechanism composed of a rotary motor and a ball-screw or slide-screw is employed. However, it has some problems such as the decrease of the drive efficiency, flexibility against external forces, noise, etc. Various linear actuators and motors have been developed utilizing the feature of a direct drive. Aim: In this paper, we propose a novel linear actuator which 2 movers can be independently controlled using 3-phase and 6-phase superimposed currents for decreasing the size and weight of the system. The proposed linear actuator is driven by the operating principle of a vernier motor which is expected to achieve a high thrust force density per permanent magnet volume. Methods: The operating principle and the static thrust force characteristics of the proposed linear actuator are verified by an electromagnetic field analysis using 3-D finite element method, and the back electromotive force characteristics are also analyzed. In addition, the dynamic characteristics under position feedback control are analyzed. The control system uses a vector control using PID controller, and the control input is given by the 3-phase and 6-phase superimposed currents. Results: The static force characteristics were investigated. From the analyzed results, the force interference between the two movers was small. Moreover, the interference of the back electromotive force of the 3-phase and 6-phase movers were not observed. The movers could be independently driven under position feedback control using 3-phase and 6-phase superimposed currents. The dynamic characteristics analyses showed that the mover well followed a target position. From a step response, the time constant and the response of the position feedback system were investigated. Conclusion: This paper presents a linear vernier actuator with two movers. The basic structure and operating principle of the actuator were described. Moreover, the static characteristics and the dynamic characteristics under position feedback control were analyzed. It was found that the movers can be independently driven.

The humanity is entering the 6th technological paradigm. The technologies that shape it, form new sectors of the economy, will trigger change in educational programmes, and emergence of innovative modes of transport and connection. Maglev transport system, where one of the key advantages over conventional transport is full automation, is a powerful instrument for innovative development of mainline infrastructure, and an optimal solution, that enables achieving digital the socialization of public transport. In accordance with the laws of transition to the next technological paradigm, transport will face a technical revolution. The existing transport development model is maintained by gigantic infusion of resources. However, it is obvious that this is a backward model, being inadequate to both the society and business. The development of projects of innovative transport based on maglev technology, will foster development of new materials, technologies and hardware. The maglev technology is multifunctional, it allows engineering transport systems for various purposes, that correspond to consumers changing demand. Its application spheres are not fully exposed yet. However, the key issues, such as economic efficiency, aptitude to meet the societys and economys demand, are proved and obvious. The Russian president supported project of construction of the Moscow-Saint Petersburg high-speed mainline is ideal for realisation on the basis of maglev technology. The innovative technology that is able to provide disruptive development of Russias transport infrastructure is the maglev technology. Its application in transport industry, that plays a decisive role in development of safety and the countrys connectivity, will secure Russias leading position today and guarantee stable economy development in the future.

Passenger transport is a basis in the transport system of any country. The task of transport is to provide an opportunity for every person to reach any point of our planet, not only safely, comfortably and quickly, but with little expenses. Aim: the arm of this study is to evaluate dynamics and share of transport expenses in population of the Russian Federation, and to study interrelation between figure of transport expenses of population and its transport mobility, and passenger transport fares. Methods: to achieve the set aim, such common scientific methods as observation, analysis, generalization, and analogy were used. Results: it is noted that transport expenses of the population increase at a slower pace than consumer spending. When considering the factors affecting the transportation costs of the population, it was determined that against the background of decreasing volumes of passenger traffic there is an increase in transportation tariffs. When comparing the indices of passenger tariffs and the consumer price index, a rapid increase in the cost of passenger traffic compared to prices for consumer goods was noted, which makes transport services less accessible to the public. Conclusion: The accelerating pace of life and economic realities today pose to transport companies certain tasks to ensure high speeds. High-speed ground transportation is coming to the fore, one of the types of which is a magnetic-vehicle transport, which, in addition to high speed, has certain advantages, such as safety, comfort, energy efficiency and high throughput. The development of new high-speed modes of transport, including a magnetic-casting, will ensure a high level of transport mobility and, accordingly, the country's economic development.

Global socio-economic trends require a dramatic acceleration of transport links. The creation of new high-speed transport systems is an urgent task, the success of the solution of which largely determines the improvement of the quality of life and the trade and economic development of states, regions, cities. The main strategic goal of the development of the transport system is to meet the needs of society, taking into account the value of time and using innovative factors focused on the effective development of a competitive environment, offering quality transport services based on developed infrastructure, and a high level of application of innovative techniques and technologies. The Russian railways as a transport system need a good restructuring due to the fact that its qualitative characteristics, especially infrastructure, are not able to efficiently solve the existing problems of the global economy. The aim of this article is to study perspective trends for the development of the railway sector in the context of digitalization of the economy.

Background: At high speeds of motion of the magnetic-levitation transport (MLT), linear induction motors (LIM) have a secondary longitudinal edge effect (SLEE). SLEE occurs when magnetic field of inductor interacts with the currents of the secondary element (SE) outside the MLT crew. SLEE reduces the efficiency of traction LIM. Therefore, the task of reducing the influence of SLEE is relevant. Aim: Development and research of a linear induction motor without a secondary longitudinal edge effect. Methods: To achieve this aim, new designs of linear induction motors have been proposed, which do not have a SLEE. The secondary element of the LIM (track structure of the MLT) is made of cylindrical conductive rods installed with the possibility of rotation. Traction LIM of the MLT equipped with two brushes that close the rods of the SE within the length of the inductor. When the MLT crew moves, the rods outside the inductor are not closed by brushes and there is no current in them. There will be no SLEE. Another method to solve this problem is using reed switches to close and open the rods of the secondary element. Results: The possibility of increasing the efficiency of the LIM has been achieved.

Background: The arch trestle allows using two working surfaces: internal (under the arch) and external (over the arch) which may be used for moving of the transport pods. Transport pods include magnetic field sources, and the trestle is equipped with a stator winding. The stator winding is subdivided into the accelerating winding and suspension and levitation winding. As an option, the winding providing levitation can be replaced with permanent magnets. Aim: to show capacities of the arch trestle for transportation of passengers and goods. Methods: patent search, modeling. Results: simultaneous transportation of goods and passengers is possible both in the same and opposite directions. Conclusion: the efficiency of the transport system increases due to bilateral movement of modules.
