Complete solutions of electronics for electric mining locomotive EE-90K
Comprehensive solution for the mining traction locomotive electronics. For the main drives, the SEMIKRON SEMiX equipped inverters are based on the proven UNIFREM platform. For each locomotive drive, unique torque-speed vector control is used – the joystick on the control panel in the locomotive cabin is not only the speed reference, but also the torque reference. The torque between the individual drives is intelligently electronically balanced for the smooth operation of the locomotive. The locomotive control system is based on the SIMATIC S7-1200 system, it has a color display.
