The compelling case for high-pressure geroler motors

High Torque Low Speed (HTLS) motors using gerotor and geroler technology have been in use since the 1950s but are generally considered for low and medium pressure applications.

Eaton has been expanding the envelope by developing geroler motors that operate reliably at higher pressures, up to 345bar (intermittent pressure drop). High-pressure motors are able to accomplish more in a smaller package compared to medium-pressure technology.

When it comes to enhancing performance of both mobile and stationary hydraulic systems, high-pressure technology can be used to reduce package size, improve starting torque, and reduce system costs. At the end of the day, this means that skid steer loaders, drilling equipment, grinders and mixers, material handling and other mobile equipment can get more done, generate less emissions and use less fuel.

Switching from medium to high-pressure models is typically driven by three factors:

1. Equipment size: as machines become more compact and nimble, higher pressure products allow the same capability in a smaller envelope.
2. Capability gains: applications where more capable motors yield more productive or efficient machinery
3. Future compatibility: supporting future upgrades and changes
