Abstract
The article deals with analysis of the impact of the law change control parameters on the character of transient processes in a mode of constant power of switched reluctance motor mine locomotive using models developed for the program Simulink software package Matlab. As the control parameters selected number of turns of the phase, angle of inclusion Θon and the angle Θoff. The results of calculations on these models for the motor capacity of 27 kW and a rotation speed 1215 r / min. It is shown that with a constant number of turns with increasing speed in the range of 1: 3 angle Θon growing almost to the critical, deteriorating the shape of the phase current and increase torque ripple. After reducing by half the number of turns in the middle of the range dramatically reduced torque ripple, improve the shape of the current and reduce the angle Θon, thus expanding the range of speed control in this mode.
