Results of testing the shearer advance system with two motors integrated with frequency transducers were presented. Comparison of new solution of advance drive system, which consists in implementation of two haulers in which motors of 1000 V supply voltage are installed (each of them is supplied from frequency transducer integrated with the motor) with currently used system, where two haulers with motors of 480V are used and they are supplied from one frequency transducer installed outside the haulers, was the objective of research work conducted by the KOMAG Centre.
