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.
