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 mag-
netic 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 de-
velop 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 lon-
gitudinal and transverse magnetic flux is greatly influenced by the character of current distri-
bution in the secondary element. The character itself is influenced by MF distribution in the
air gap.
