Axial piston hydraulic motor
Oilgear

Oilgear's MFW and MVW fixed and variable displacement bi-directional high-speed motors are offered in two frame sizes and four displacements, allowing for greater flexibility to match pressure and capacity.

The MFW fixed displacement motor maintains constant torque with varying horsepower. Because the motor is fixed, maximum torque is available at all times when in operation, whether the motor is stalled or operating at full rpm. Horsepower output is approximately proportional to speed, making it is possible to reduce pump delivery when stalled, or bring the motor and load up to speed while maintaining full torque.

The MVW variable displacement motor can operate with constant horsepower and variable torque, or with constant torque or constant horsepower. When operating with constant horsepower and varying torque, the MVW motor can adjust speed over a 4:1 range when driven by a fixed delivery hydrostatic pump. When a variable displacement motor is driven by a variable delivery pump, constant torque or constant horsepower at variable speed can occur.
