    Why can DMS08 Low Speed ​​High Torque Piston Motor have high speed and low torque?

    1. Innovation in design concept
    The low-speed, high-torque characteristics of the DMS08 low-speed, high-torque motor
    first come from the innovation of its design concept. Traditional motors often pursue high speeds in exchange for greater power output. In certain specific application scenarios, such as heavy machinery, precision machining equipment, and occasions requiring strong traction, low-speed, high-torque motors are more suitable. Based on this demand, DMS08 achieves stable and strong torque output at a lower speed by optimizing key design elements such as piston stroke, cylinder layout, and transmission mechanism.

    2. Exquisite coordination between piston and cylinder
    The core of the DMS08 piston motor lies in the exquisite coordination between its piston and cylinder. By increasing the piston diameter and stroke, each working cycle generates greater thrust, which is then converted into greater torque output. The design of the cylinder also fully considers the principles of fluid mechanics to ensure that the hydraulic oil flows smoothly in the cylinder, reduce energy loss, and improve transmission efficiency. The piston and cylinder are made of high-strength wear-resistant materials, which not only prolongs the service life of the motor, but also ensures the stability of long-term operation.

    4. Synergy of hydraulic system
    The low-speed and high-torque performance of DMS08 plunger motor is also inseparable from the synergy of hydraulic system. The hydraulic system provides stable and adjustable driving force for the plunger motor by controlling the flow and pressure of hydraulic oil. In the design of DMS08, the hydraulic system adopts advanced control technology and efficient pumps, valves and other components to ensure that the motor can provide appropriate power support under different working conditions. By optimizing the layout and parameter settings of hydraulic circuits, energy loss can be further reduced, transmission efficiency can be improved, and the low-speed and high-torque performance of the motor can be enhanced.
