Abstract (en)

[origin: DE19513987A1] Proposed is a hydrostatic radial-piston motor (10) with an adjustable cylinder ring (18) which has integrated means designed to determine the eccentricity (20) between the cylinder ring (18) and the rotor (14). The eccentric position of the cylinder ring (18) leads, in conjunction with the rotating rotor (14) and the restraining of the guide shoes (17) on the cylinder ring (18), to a stroke action of the piston (16) in the radial direction. This, and kinematic conditions in the motor (10), leads to a change in the distance between two consecutive guide shoes (17). This change in distance takes place in proportion to the eccentricity (20) of the cylinder ring (18) and is determined by a measuring device. This measuring device has a signal transducer (27) which generates an amplified voltage signal as the guide shoes, which act as signal generators, move over it. This signal is fed to evaluation electronics (28) where it is used to determine the eccentricity, rotor rpm and other parameters.
