A6VM oblique axis variable motor
The A6VM inclined shaft variable motors are of an inclined shaft axial piston design with an integrated axial tapered piston structure. This design makes the motor suitable for hydraulic transmissions in open and closed circuits.
The A6VM tilting shaft variable motor is used in the mobile and stationary equipment industry to meet the requirements of high speed and high torque. Its wide range of adjustment allows for excellent performance in a wide range of operating conditions.
Product features
◉ Wide adjustment range: With a wide range of adjustment, the variable motor is able to meet high speed and high torque requirements.
◉ Speed ratio relationship: The output speed is proportional to the input flow rate and inversely proportional to the displacement.
◉ Torque impact factor: Output torque increases with the increase of pressure difference between the high and low pressure sides of the motor and with the increase of motor displacement.
◉ Excellent driving characteristics: Wide adjustment range of hydrostatic drive, a variety of control variables device, good starting characteristics.
◉ Excellent structural performance: Compact structure, durable, excellent power/weight ratio.
