Features
  • wide adjustment range Handles both high-speed and high-torque demands, making it versatile for various applications.
  • infinitely variable displacement control Seamlessly adjusts from maximum displacement (Vg max) down to zero (Vg min = 0), ensuring precise hydraulic control.
  • proportional speed regulation Output speed adapts directly to input flow and inversely to displacement, optimizing your system’s performance.
  • adaptive torque output As pressure differential and displacement increase, the motor automatically enhances torque output, delivering the power your system needs.
  • smooth hydrostatic drive A broad adjustment range, multiple control options, and excellent startup characteristics make it a versatile and efficient solution.
  • cost-saving design By eliminating gear reducers and requiring a smaller hydraulic pump, this motor helps reduce system costs without compromising performance.
  • compact and durable build Designed for long service life, featuring a high power-to-weight ratio and outstanding volumetric efficiency to keep your system running longer with minimal maintenance.
