Char-Lynn® Gerotor/Geroler Motors
The Char-Lynn® brand has been recognized as the industry leader in low-speed, high-torque (LSHT) hydraulic motor technology for more than 45 years. Named after the late hydraulic industry pioneer, Lynn Charlson, Char-Lynn motors are based on what he called the Orbit Principle which gives them their reliable high power density, modularity and economic design. A wide variety of displacements are available in each of the 3 Char-Lynn product families:
- Spool valve motors
- Disc valve motors
- VIS (Valve-In-Star) motors
These products can be easily customized to a wide variety of application needs.
Eaton disc valve motors allow higher flows and higher pressures than spool valve motors, resulting in higher torques and efficiencies. All are available in standard mount, wheel mount, or bearingless configurations with many shaft and port options and speed sensors to meet a broad range of application requirements. Eaton disc valve motors deliver unrivalled quality and are supported by manufacturing systems that ensure on time delivery.
Char-Lynn spool valve motors distribute pressurized fluid into and out of the orbit gear set (gerotor or geroler) via valve slots integrated into the output shaft which also incorporates hydrodynamic journal bearings. The spool valve section can be optimized for low flow, low speed needs, using a low speed spool option to enhance smooth running performance
Eaton Valve-in-Star (VIS) motors are the next step in the evolution of low speed high torque (LSHT) hydraulic motors. The VIS design provides a more compact package, better efficiency and higher pressure capability than other types of LSHT hydraulic motors. Eaton VIS motors are primarily intended for use in closed loop applications.
