Have dificult to search.

Whats brand have motor specifications:
Min RPM 10 RPm or less and less 2 in3/rev
Torque 780 lbf.in (if possible)

Have webpage, for select product byhigh numbers manufactures !?

Go to the Home Page of this Forum and look at "Motors, low-speed/high-torque" in the "Designers Guide" and take your pick.

I check list. All motors have small torque and high consume.

My priority is high torque and high autonomy.
I get luck, search motor less 1 ml/revolution and torque big.

My interpretation is correct? Its all motor less 2ml oil for 360º.

I don't see how a 1ml (1 cc, or 0.06 cubic inches) motor can put out 1100lb-ft (1450 N-m) at 2320psi (16 MPa). According my my calculations, that gives you 22 lb-ft. You would need 115 000 psi with a 0.06 cubic inch motor to acheive 1100 lb-ft. LOL

There's a general dichotomy with hydraulic motors; you trade displacement/torque for speed or trade speed for displacement/torque. High torque motors generally turn slowly. High speed motors generally have no torque.

Sampo makes radial piston drive motors that operate efficiently at 20 RPM, where they put out 29 500 lb-ft (40 000 Nm). Of course they require 26 GPM (100 l/min) and almost 6000 psi (400 bar).

This is the opposite extreme, of course, but you get the picture.
