Porównanie parametrów trakcyjnych lokomotywy kopalnianej wyposażonej w różne typy napędu z silnikami prądu stałego i zmiennego

The paper presents the electrical and timing characteristics of drive systems of battery locomotive weighing 12 tons, equipped with electric drive motors of various types. Analysis is done using the DC motor drive, used commonly in today locomotives and AC motors, asynchronous squirrel-cage and synchronous with permanent magnets. Presented results obtained by simulation of trains equipped with these types of drives, and energy balance was made on the sample transport route. Presented in this paper simulation results of different types of drives, the propulsion engines allow to choose the drive when upgrading mine locomotives.
