Abstract

Background. The development and research of linear induction traction drives for magnetic-levitation transport is an urgent task. Linear induction motors can be used as the main traction machines for advanced transport and as additional traction machines for traditional rolling stock.

Aim. This study aims to research on the features of regulation of a traction linear induction motor with variable resistance by short-circuited winding of the secondary element.

Materials and methods. The ratios for calculating the resistances of the short-circuited winding of the secondary and starting traction forces of an adjustable linear induction motor are analytically established.

Results. The obtained ratios made it possible to calculate the starting resistances of the short-circuited winding of the secondary element and the traction forces of the engine.

Conclusion. This study of the regulation of the resistance of the short-circuited winding of the secondary element and the starting traction forces of a linear induction motor provides guidance on choosing rational modes of switching on the motor.
