Hydraulic Motor Selection

If you are going to use an Eton drive motor, then contact Eaton engineering and have them advise you as to what motor will fill the bill for you.

thanks for ur quick and clever answer...........

You don't say how fast you want the load to move. With given oil q and P, power in oil = 18.67kW. This gives max velocity of load ~ 0.9m/s, 238 sprocket rpm for torque 750Nm. OK if you need lower speed, but supplier has to know.

Above ignores efficiency of the hydraulic motor but this is likely to be ~ 90%, so covered by your 1.3 safety factor, but need to check.

Every Fluid Power, (hydraulics & pneumatics,) Distributer has Application/Sales Engineers available to assist customers in choosing the proper product for the application presented.

CALL YOURS!

To Hilltop & Prbarry, I say, "I thought this was an engineering column!"

The following link: http://hydraulics.eaton.com/products/motors_main.htm takes you to the main Eaton Motor page. PDF catalogs are available from this page forward for all the motor types Eaton has. All the catalogs have easy to use performance charts giving you torque & RPMs at given flow & pressures for all displacement motors. I personally like the 2000, 6000, and 10000 Spool motor series, but normally working in imperial units, I can't tell you off hand whether these are appropriate for your application.

Silver Ghost,

You are right, this is an Engineering column.

But part of being an engineer is knowing where to get the proper information you need in order to make informed decisions as to the components you will use in a particular application.
The best source of information is from the manufacture/distributer of a particular item.

They know their products and are aware that they will ultimately be liable for misapplication.

(Personally, I would not take an individual's product recommendation as gospel, but as another product to be investigated.)

We are part of this site in order to offer helpful advice.
Part of that advice would include places to go to get information.

In 30 years of successfully designing various machines ranging from agricultural equipment, food processing equipment, semiconductor manufacturing equipment and medical equipment, I learned that the world of engineering is very complicated.

Ultimately, we all need input from various sources in order to do our jobs efficiently and to deliver the best design we can.

You say in your last sentence, "I can't tell you off hand whether these are appropriate for your application."

But an application engineer from the Manufacture/Distributer of Eaton can!
