Hydraulic Gerotor & Geroler Motors

With a design based on the Orbit Principle in which an internal gear rotates inside of an external fixed gear, these gerotor motors are known for their reliable high-power density, modularity and economic design.

Only three primary moving components are needed to transmit torque through the motor: star, drive and output shaft. Shaft rotation can be instantly reversed by changing inlet / outlet flow while generating equal torque in either direction. A variety of displacement sizes are available in each motor family that provide a wide variety of speeds and torque ranges from any series of motors. The results are compact, modular, economical designs that can be easily customized to suit a wide variety of application needs. 

Motor options include:

  • Displacement size (cubic inches or cc's per revolution)
  • Output shaft size and type
  • Mounting flange type
  • Porting interface
  • A wide selection of special features such as integrated brakes, sensors, integrated cross-over relief valves, 2-speed capability, manifold valve packages and environmental protection suited for corrosive environments.
