THE ANALYSIS OF MEANS OF IMPROVING CHARACTERISTICS OF LINEAR INDUCTION TRACTION MOTORS FOR HIGH-SPEED GROUND TRANSPORT

The paper considers methods of improving the performance characteristics of high-speed linear induction traction motors (LITM). The theory of these machines is given based on the analysis of a three-dimensional magnetic field and it enables the characteristics of the motors having single-side or double-side inductors with any type of wind and different types of reactive buses (solid, laminar) to be calculated. A comparison of the calculated characteristics with the experimental data for the previously investigated model of LITM and of the high-speed LITM tested at Pueblo (USA), proves the accuracy of the calculations. Use has been made of the engineering method of calculation given in the previous article for making a general and effective analysis, and methods, have been determined for increasing tractive effort and improving other characteristics of the LITM. A more precise quantitative analysis and calculation of expected characteristics has been made based on the three-dimensional theory. It has been shown that the best effect may be obtained by reduction of the reactive bus conductivity to a rational value with a correct choice of the pole pitch of the inductor. The use of three-phase compensation windings is not effective. An analysis of the characteristics of motors with single-layer and double-layer windings for an odd and even number of poles is given.
