The problems of improvement of modern types of transport and creation of new ones are important and topical for the human society development. One of the most promising and environmentally-friendly modes of transport is the high-speed maglev transport, moving at speeds of approximately 500 km/h. Objective. Justification of linear induction motor, development and research of various constructions of this type of motors. Methods. Description of linear induction motor with longitudinal and transverse magnetic flux for combined traction and lateral stabilisation system of maglev transport, having increased lateral stabilisation forces. The mathematical modelling of magnetomotive force (MF) in the air gap of traction linear motor of this type has been conducted. To analyse the MF the assumption has been made about even distribution of magnetic induction in the air gap in transverse direction and its sinusoidal longitudinal direction, making it possible to develop new mathematical model of MF distribution in the air gap of linear induction motor with longitudinal and transverse magnetic flux Results. The developed mathematical model for calculation of MF on traction linear machine will enable increasing accuracy of traction and lateral stabilisation combined system forces for maglev transport. The same relates to mutual location of inductor to the secondary element. All this proves the successful ten-year commercial operation experience of magnetically suspended train carrying passengers from an airport to Shanghai, P.R. China. The values of traction and lateral stabilisation forces of linear induction motor with longitudinal and transverse magnetic flux is greatly influenced by the character of current distribution in the secondary element. The character itself is influenced by MF distribution in the air gap.
Background: Currently, great attention is paid to the problem of increasing the efficiency of transport in cities. The use of urban Maglev transport with linear traction motors will improve the transport infrastructure of megacities.
Aim: The use of magnetic-levitation transport with linear induction motors (LIM) is proposed. It is proposed to use traction linear induction motors (LIM) for urban Maglev transport, increasing the safety of a new type of transport.
Materials and Methods: In this work, the design of a linear traction induction motor was proposed, which can increase lateral stabilization forces and safety of traffic by performing the lateral parts of the secondary element of a linear induction motor in the form of short-circuited windings.
Results: Improving efforts of the lateral stabilization improve crew safety.
