I have seen in many data sheets of Hydraulic Gear motor a spec called : "Minimum Speed = 450 RPM" ( 450 is an example)
In your experience or theoretical knowledge what happens If I run the motor slightly below this speed (say 150 RPM ) by reducing the flow of Oil.
Does it lose torque/or any other spec but stay running normally ?
Does it stop moving smoothly? ( I have seen this "discontinuity effect" in real life when flow is too low the motor speed was around 10RPM)
note: what I mean by discontinuity is that the motor moves a push then stops as if it is gathering oil then move a push again.
