The 51000A is a detailed model of the control module, marking exclusive configurations such as the type of control signal and response parameters
The suffix “S” is a supplementary code, usually indicating an enhanced sealing grade, adaptation to special working conditions (such as dusty and humid environments), or a specific industry standard adaptation version

Product attributes
The specific content of the attribute category
Core type: High-pressure adaptive control inclined shaft axial piston variable motor
Key parameters: Nominal pressure 400bar, maximum pressure up to 450bar. Maximum displacement: 107cm³/r; At the maximum displacement, the rated speed is 3550rpm, providing stable output under high-pressure conditions
The adapter circuit is compatible with both open and closed hydraulic circuits and is suitable for the hydrostatic transmission systems of mobile machinery and industrial equipment
The adaptation scenarios are mainly used for heavy equipment such as drilling RIGS and excavators, and can also be adapted to working conditions that require high torque output, such as pile driving machinery and port lifting equipment
The structural configuration can be selected as flat key shaft or splined shaft, equipped with standard flange connection, and supports two interface types: flange oil port and threaded oil port

Working principle
This motor adopts an inclined shaft structure and an axial conical plunger rotation assembly design. After high-pressure hydraulic oil enters the motor, it drives the internal plunger to move back and forth. The plunger exerts a force on the inclined cylinder block, thereby forming the torque that drives the cylinder block to rotate. Its displacement can be steplessly adjusted from maximum to zero through the control mechanism. Specifically, the HA high-pressure adaptive control module senses the pressure changes in the system and automatically adjusts the inclination Angle of the inclined axis to change the effective stroke of the plunger. The greater the Angle of the inclined shaft, the longer the plunger stroke, the greater the displacement, the greater the output torque and the lower the rotational speed. Conversely, the displacement decreases and the rotational speed increases. Eventually, in this way, the dynamic adaptation of torque and rotational speed is achieved, converting hydraulic energy into stable mechanical energy and transmitting it to the load.

Product features
Strong adaptability to working conditions: The maximum pressure of 450bar is suitable for high-pressure and heavy-load scenarios. The wide adjustment range can simultaneously meet the dual demands of high speed and high torque of the equipment. No additional transmission is required, and it is compatible with the complex working conditions of various heavy machinery.
Precise and flexible control: The HA high-pressure adaptive control mode can automatically adapt to system pressure fluctuations with a fast response speed. Combined with the VSD control module, it can achieve precise speed and torque adjustment, adapting to the dynamic changes of different loads.
Reliable and durable structure: The compact and sturdy bearing system extends the service life. The inclined shaft has a large swing range and a small moment of inertia, with high starting efficiency. It can adapt to frequent start-stop conditions and reduce mechanical losses.
Outstanding economic performance: No need to configure a shift transmission, and it can be used in conjunction with a small hydraulic pump, reducing the overall volume and cost of the system, while lowering energy consumption and enhancing the comprehensive operational efficiency of the hydraulic system.

Installation and operation
Installation specifications: The bottom-mounted installation is preferred to ensure that the motor is below the lowest oil level in the oil tank. If the top-mounted installation (with the shaft facing upwards) is adopted, a check valve with an opening pressure of 0.5bar should be installed on the oil discharge pipeline of the housing to prevent oil leakage and insufficient lubrication of the bearing. Installation must be carried out by professionals, strictly adhering to the tightening torque specified in the VDI2230 standard to prevent thread damage. The oil drain port at the highest point of the shell must be connected to a pipeline to the oil tank, and the pipeline outlet must be lower than the lowest oil level in the oil tank.
Operation requirements: Before the trial run, the motor should be filled with hydraulic oil and all the air drained. After a long period of shutdown and restart, this operation should also be repeated. During operation, it is necessary to monitor the temperature of the oil and the shell. The high temperature in the electromagnet area can easily cause scalding, so protective measures should be taken. It is necessary to use hydraulic oil of the appropriate specification to avoid the mixture of impurities. It can be equipped with accessories such as flushing valves and booster valves to prevent contamination and maintain the stability of system pressure.
