[0002] Axial fixed-displacement motors are a type of hydraulic transmission equipment commonly found in hydraulic systems, used to produce high-torque and high-speed outputs. They typically adopt the design of axial pistons or axial piston pumps / motors. The working principle of these motors is based on the pistons moving along the axis, causing hydraulic fluid to generate pressure inside the motor and driving the motor to rotate. Axial fixed-displacement motors are usually larger and may be more elongated or tubular in shape to accommodate the pistons and other hydraulic components inside. The shapes and sizes of ordinary motors may be more diverse, depending on their specific types and application scenarios. The external accessories of axial fixed-displacement motors may be related to the connection method of their hydraulic systems, such as the connection interfaces of hydraulic pipelines. The external accessories of ordinary motors may be related to the connection of their electrical systems, such as power lines and control lines, etc. Since axial fixed-displacement motors are usually used in industrial applications, their installation methods may need to consider more mechanical structures and supports to ensure their stability and safety. Generally, the shock-proof effect, heat insulation ability, and heat dissipation ability of axial fixed-displacement motors are not good.
