NHM JMDG NAM Hydraulic Motor | Radial Piston Motor | LSHT Wheel Drive Motor | High Torque Oil Motor

NHM, JMDG, NAM Series LSHT Radial Piston Hydraulic Motors

Product Overview: The NHM, JMDG, and NAM Series are classic crankshaft-connecting rod radial piston motors. Utilizing hydrostatic balance technology, these motors significantly reduce frictional losses, ensuring smooth operation even at extremely low speeds. With their massive output torque and high-pressure capabilities, they are the ideal power core for wheel drives, winch hoisting, injection molding machinery, and mining equipment. This category covers the full spectrum from the compact NHM1 to the heavy-duty NHM31, supporting various shaft ends (keyed, splined) and distributor configurations.

Key Technical Advantages:

• Elite Starting Torque: Thanks to the hydrostatic balancing and advanced sealing, mechanical efficiency is exceptionally high, with starting torque typically exceeding 90% of theoretical values.

• Low-Speed Stability: The unique crankshaft architecture ensures smooth output at speeds as low as 1 RPM without “creeping” effects.

• Heavy-Duty Bearing Support: Equipped with high-strength tapered roller bearings, these motors can withstand significant radial and axial loads, allowing for direct drive of heavy wheels or winches.

• Rugged Longevity: The simple modular design makes maintenance straightforward, and they are far less sensitive to oil contamination than axial piston counterparts.

• Target Applications: Injection molding screw drives, marine winches, construction drill rigs, and specialized vehicle wheel drives.
