As a result of the study, an experimental test bench was developed for testing high-torque hydraulic motors. A methodology for experimental studies of a unified series of planetary hydraulic motors has been developed. It has been established that an increase in the throughput of a hydraulic motor with a modernized distributed system makes it possible to increase the hydromechanical efficiency of the modernized hydraulic motor by 11 to 14%, the volumetric efficiency by 2 to 4%, and the overall efficiency by 7 to 9%. The increase in the values of the hydromechanical, volumetric and overall efficiency of the modernized hydraulic motor explains the increase in the throughput of its distributed system. It has been established that the torque of the developed serial hydraulic motor is 300 to 325 min −1 , which is a sign of the rigid characteristics of this hydraulic motor. The stability of the torque (within 1.5%) developed by the modernized hydraulic motor 370 to 375 H.m in the frequency range of 75 to 450 min −1 is confirmed by its rigid characteristic.
