Hydraulic Motor
 

Does anyone know of a company that makes micro hydraulic motors like the ones used in the Hidromek 490 excavator? Or can you possibly use a hydraulic gear pump as a motor?

GBH Modellbau offers 2 different models...but very few technical information available from the website...

My memory of the relationship between pumps and motors is that any motor can be used as a pump, but pumps must be modified in order to be used as motors. AvE has a video on this topic (beware of language - he does have a tendency to swear a bit, along with some crude jokes at times). Good info, regardless. One of the things he does on his channel is take things apart to show how they work (generally tools, but other small appliance-like things as well).

I believe the modification is a pressure seal on the shaft. He goes over it in the video.

I had a look at the website for Modellbau, and it’s all in German and you can only register a German address to sign up, a little bit frustrating.
