Testing of selected designes drive systems of mine battery locomotives

The paper describes stand tests of innovative drive system of Lea BM-12 mine battery locomotive, which are realized within the project number N R01 0009 06 entitled "Mechatronic drive system for rail vehicles designed to operate in explosive atmosphere". The innovative drive system of Lea BM-12 mine battery locomotive includes permanent magnet synchronous motor (PMSM) vector controlled from the voltage inverter. New drive system is supplied from explosion-proof battery pack. Scope of testing included preparation and implementation of regulator's primary system, which controls locomotives drive system cooperating with braking device and testing of Lea BM-12 drive system according to known work cycle of the locomotive which was developed basing on the real communication system in one of mines.
