Abstract
Application in mines and mines of asynchronous engines with a phase rotor is limited by safety rules. Miner electric locomotives with direct current motor with consecutive excitation gained the greatest distribution. The modern level of development of control systems allows creating various mechanical characteristics. The questions of possible use of the asynchronous engine with a short -circuited rotor in system of the electric drive of a miner accumulator electric locomotive are considered. Functional and block diagrams of a control system of the asynchronous drive of a mine electric locomotive are offered. The model realization of the asynchronous electric drive in the environment of imitating modeling of MatLab/Simulink is accomplished. The results of modeling of system of the electric drive with the asynchronous engine are given. The control of the drive is simulated by the four-position controler, and feedback - on resistance moment. The special attention is focused to questions of formation of mechanical characteristics of the asynchronous electric drive of a mine electric locomotive. The block d iagram of the model of the asynchronous drive is developed. It allows receiving a range of mechanical characteristics approached to the mechanical characteristic of the direct current motor with consecutive excitation.
