Hey guys, as part of a Uni project I need to source some small hydraulic motors and I was wondering if anyone could point me in the right direction? These need to be as small as possible due to clearance issues. Also the higher torque output the better
Cheers!

you can even have the hydraulic rams off them too...

ooh, whats a hydraulic motor then? i thought they were another name for the electric pump thing (using electric motors rather than engine driven)

ah, for driving wheels with hydraulics, sorry

You could try this site:

http://www.hydraulicsonline.co.uk/hydraulic-motors/omm-hydraulic-motor%20/omm-gerotor-125cc-hydraulic-motor-60.html

or rs has small gear motor which you can drive backwards of course.

Ta for that guys After looking I reckon I'm gonna need a radial motor for the high starting torque, but I don't think they make them as small as I need

If they are that small wouldnt an electric motor be a more cost effective and simpler option!?

Maybe, I'm after a high torque and compact motive power. Also needs to be as light as possible etc. I've always thought of small electric motors as signficantly lacking torque. Also a hydraulic motor can't be back driven, which is useful in this application

Edit: Just realised I havn't said what it's for- it's a mechanical arm. Doesn't need massive power, only lifting about 75kg or so.

We use electric driven rams at work. Also called actuators!!

Some of them are beasts and quite small.

I work with wheelchairs and rebab so look down that line maybe. Powered elevating leg rests and hoists are common.
