Sauer Hydraulic Motor 51V Series

Sauer Hydraulic Motor 51V Series

Type: Axial piston motor with variable displacement bent axis design
Series 51 and 51-1
Size: 060 080 110 160 250

Series 51 and 51-1 variable displacement motors are bent axis design units, incorporating spherical pistons.
These motors are designed primarily to be combined with other products in closed circuit systems to transfer and control hydraulic power. Series 51 and 51-1 motors have a large maximum / minimum displacement ratio (5:1) and high output speed capabilities.

SAE, cartridge, and DIN flange configurations are available. A complete family of controls and regulators is available to fulfill the requirements of a wide range of applications.

Motors normally start at maximum displacement.

This provides maximum starting torque for high acceleration.

The controls may utilize internally supplied servo pressure.

They may be overridden by a pressure compensator which functions when the motor is operating in motor and pump modes.

A defeat option is available to disable the pressure compensator override when the motor is running in pump mode.

The pressure compensator option features a low pressure rise (short ramp) to ensure optimal power utilization throughout the entire displacement range of the motor.

The pressure compensator is also available as a stand-alone regulator.
