ABSTRACT:
A power supply system for a drum-cutter mining machine utilized in longwall mining operations. Three-phase electrical power is supplied to a rectifier circuit positioned remote from the mining machine to rectify the three-phase electrical power. Rectified electrical power is supplied to the mining machine through cables, whereat the electrical power is inverted by inverters. Power transistors are coupled between the inverters and the respective motors of the mining machine. Positioning the rectifier remote from the mining machine allows the body of the mining machine to be of reduced dimensions.
