Abstract / scope
This document specifies a procedure for the determination of a rating of the source flow ripple, source impedance and pressure ripple levels generated by positive-displacement hydraulic motors, including bidirectional motors.
This document is applicable to all types of positive-displacement motor operating under steady-state conditions, irrespective of size, for frequencies from 50 Hz to 3 500 Hz. It is applicable for the inlet port of positive-displacement motors.
