In this paper was processed topic of experimental analysis of a toothed hydromotor under variable load. For the purposes of analysis and measurement it has been used system build at the Faculty of Engineering in Rijeka. The system is designed, engineered and adapted for experimental hydromotor analysis. In order to perform an experimental analysis of system it is necessary to know the specification and role of each individual component used in the system. The system can be divided into three subsystems, a hydraulic system, a brake system, and a measuring devices which are used to measure the work parameters in the system. Braking hydromotor testing is performed to determine its propertis, which makes it easier to predict system behavior during exploitation. Measurements were made by changing the braking intensity of the hydromotor step by step and we measured the value of the every parametar at each intensity. The measurements were repeated several times to ensure the accuracy and repeatability of the measured size. In the paper are presented results obtained by measuring and analyzing system and the physical sizes we have in the system are explained. The results obtained by measuring are compared with the data that the manufacturer of the hydromotor provide with their product . In addition to system comparisons, the goal is to identify the advantages and disadvantages of the current system and to study ways of improving the existing system of breaking hydromotor in the future.
