Sauer danfoss 51V160 bent axis variable displacement motor

The 51V160 belongs to the Series 51 family of bent-axis variable displacement motors from Danfoss Power Solutions (formerly Sauer-Danfoss). Its “160” designation refers to the maximum displacement: 160 cm³/rev. It uses a bent-axis design, meaning the cylinder block is angled relative to the drive shaft—typically at 40 degrees—which allows higher operating pressures and smoother operation compared to swashplate designs.

Variable Displacement Control Options

One of the strongest selling points of the 51V160 is its flexible control architecture. You can choose from several integrated control systems depending on your application:

1. Hydraulic Remote Control (HD)

A simple pilot-pressure input adjusts displacement proportionally. Ideal for open-loop systems where an operator manually controls speed via a joystick or foot pedal.

2. Electric Proportional Control (ED)

Uses a 12V or 24V solenoid to modulate displacement based on current input (typically 200–600 mA). Perfect for PLC-controlled or CAN-based machinery like automated guided vehicles (AGVs) or robotic excavators.

3. Load Sensing / Pressure Compensated (LS/PC)

Automatically reduces displacement when system pressure exceeds a set threshold—protecting both the motor and the pump from overload. Commonly used in fan drives or conveyor systems where the load varies unpredictably.

4. Constant Power (Power Limiter)

Adjusts displacement to keep power consumption within a preset limit. This prevents engine stall in diesel-hydraulic systems—critical in forestry mulchers or rock crushers.

Tip from the field: If you’re retrofitting an older machine, the electric proportional control (ED) is often the easiest to integrate because it only needs a clean PWM signal and a return line. No additional pilot plumbing required.

Common Applications

Mobile Cranes and Boom Trucks

The 51V160 powers winch drums and slewing rings. Its ability to shift from high-torque/low-speed (full displacement) for lifting to low-torque/high-speed (reduced displacement) for fast line payout saves cycle time.

Drilling Rigs

Rotary heads demand constant torque across varying RPM ranges. The 51V160’s bent-axis design delivers steady torque even as rock hardness changes, reducing bit chatter and extending tool life.

Agricultural Sprayers and Spreaders

Variable-rate application requires precise wheel speed control. With the 51V160, operators can adjust ground speed independently of engine RPM, ensuring consistent chemical coverage.

Marine Propulsion and Winches

Saltwater environments demand corrosion resistance. The 51V160 features a zinc-plated housing and stainless steel control spools as standard—not just an option.
