For that kind of setup, you are in the right family. This is an Eaton Vickers 35M Series vane motor and the listed applications include elevator scraper drives, hydrostatic drives, and auxiliary applications. It is a single configuration motor with a 115 ring size and 7.44 displacement.
Question by: Rex F on Oct 14, 2025, 9:57 AM
torque rating on this motor, is that 115 lb-in per 100 psi across the whole operating range or just at a specific pressure point?
Answer by: Customer Support on Oct 15, 2025, 7:17 PM
That 115 lb-in per 100 psi figure is the rated torque output for this motor, and it scales with pressure. So if you're running at 200 psi, you're looking at roughly 230 lb-in of torque. It's a straightforward linear relationship for vane motors in this series, which makes it pretty easy to work backwards from your load requirements when sizing things out.
