Hydraulic motor for very slow rotation
Hydraulic motor for very slow rotation
(OP)
Hi all,
I am building a hydraulic drive system for a radio dish. The required speed is very low, so I can do it with a 1/2hp gear pump with a flow rate of 0.27GPM. The links to the pump and motor that I am looking at are given below.
The motor is rated for 21hp with a flow rate of 16GPM. I will not be using it at full capacity, but I need the high torque and the ability to hold against strong wind gusts, so I am using hydraulics.
My question is this: Will the motor be happy operating at such a small fraction of its capacity? I plan to use solenoid valves to control the position of the motor. How feasible is this?

It sounds like the correct type of motor for your application is the Char-Lynn type gerotor motor. https://www.eaton.com/Eaton/ProductsbyMarket/Agric...

I concern we have seen in the past is a notch filter to compensate for dish resonances when the wind blows. These can be implemented in the user program.
If the dish isn't too big you can use a Moog Flo-Tork

The flotork converts linear motion to rotational. We/our distributor have used flotork and our controllers on test nose wheel landing gear test systems.
