The problems of inverter-fed drive of hydraulic pump in volumetric control system with use typical motors, i.e.: induction (AC), brushless dc (BLDC) and synchronous permanent magnet (PMSM) have been analysed. Laboratory results of volumetric control were compared with results of throttling control of hydraulic drive system. In the speed and flow control of hydraulic systems the conventional type controllers were used. The tests were carried out for the drives with motors of 2,5 kW.
