Series H1 variable displacement motors are bent axis design, 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 H1 motors have a large maximum/minimum displacement ratio of 5:1 and high output speed capabilities.
The expanded function of zero degree capability, coupled with a high performance 32 degree maximum angle, creates opportunities to easily improve the machine performance for:
• Wheel assist on the steering axle of high inertia machines (i.e. combines) and could include Anti Slip Control
• Off-highway machines requiring Anti Slip (i.e. Ag sprayer)
• Multi-motor applications requiring optimized work and transport modes (i.e. wheel loader, Ag sprayer) utilizing the zero degree position for maximum transport speed
• Improved machine (i.e. Single Drum Roller) gradeability through precise Anti Slip Control
The Anti Slip Control reduces ground damage, increases traction control and improves machine controllability for the operator. SAE, Cartridge (not available for 250 cm3) and DIN (not available for 250 cm3) flange with radial or axial high pressure port configurations are available including the loop flushing device.
A complete family of controls and regulators are 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.
All controls utilize internally supplied servo pressure. This 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 during deceleration/braking.
The pressure compensator option features a low pressure rise to ensure optimal power utilization throughout the entire displacement range of the motor.
Speed sensor options are available to cover all frame sizes and flange styles. They are capable of sensing the following, all in one package;
• Speed
• Direction
• Temperature
