Poclain MS Motor | MS50, MS35, MS08 | Radial Piston High Torque

Poclain MS Series High-Torque Radial Piston Motors

Product Overview: The Poclain MS Series motor is the global leader in Low Speed High Torque (LSHT) drive solutions. Utilizing a unique radial piston and cam-ring design, MS motors deliver smooth and powerful torque even at extremely low speeds. This selection covers a full range of scales, featuring the heavy-duty MS50-2-D1A-R50-2A10, the mid-to-large versatile MS35-2-1C9-R35-1310-5EJM, and the compact MS08-0-121-A08-1120-000. These motors are extensively used in rotary drilling rigs, forestry equipment, mining machinery, and wheel drive systems, offering superior shock resistance even under the most severe overloading conditions.

Key Technical Advantages:

• Extreme Torque Density: The radial piston technology ensures constant torque delivery across the full speed range, with startup efficiency approaching 100%.

• Modular Configuration Options: Allows for integrated mechanical brakes (parking brakes), 2-speed displacement shifting, and various distribution backplates to fit any chassis design.

• High-Pressure Robustness: Rated for 400 Bar (5800 PSI) continuous and 450 Bar (6500 PSI) peak pressure. Reinforced stator profiles and rotor groups ensure long industrial service lives.

• Vibration & Thermal Resilience: Robust cast-iron housings are built to withstand severe mechanical shocks while maintaining high volumetric efficiency at extreme temperatures.

• Target Applications: Crawler drive systems, winch motors, road construction machinery, industrial shredders, and off-road heavy vehicles.
