  • Geroler motors are similar in design to the geroter motor, but feature better low-speed performance characteristics and higher overall efficiency. They can generate up to 15 hp. Motors with the Geroler element provide high starting and running torque as well. By minimizing friction, the Geroler element helps to increase efficiency while providing smooth output shaft rotation even at very low speeds.


  • Speed up to 1,150 rpm
  • Compact size
  • Provides high efficiency, even at start-up and low speeds
  • Motor shaft rotation can instantly be reversed by changing direction of input/output flow while generating equal torque in either direction


  • SAE ports
  • Splined and tapered shafts
