Staffa HMC125 HMC030 Motor | HMC45-Z-S03 | HMKB100T3W2A30LJ | Dual Displacement Motor

Kawasaki Staffa HMC & HMKB/HMKC Dual Displacement Radial Piston Motors

Product Overview: The Staffa Series motors are the global benchmark for high-torque propulsion technology. As high-performance Low Speed High Torque (LSHT) radial piston motors, the HMC and HMKC series are specifically engineered for heavy-duty applications requiring frequent shifts between torque and speed. This selection features core models: from the compact HMC030, the versatile HMC45, the heavy-duty HMC125, to the high-spec HMKC080T3 and HMKB100T3W2A30LJ. Renowned for its unique hydrostatic balancing technology, this series is widely used in marine winches, shredder drives, injection molding machines, and heavy material handling equipment.

Key Technical Advantages:

• Seamless Dual-Displacement Shifting: Enables on-the-fly displacement changes under load, providing a perfect synergy between “High Torque Mode” and “High Speed Mode” while maximizing energy efficiency.

• Peak Mechanical Efficiency: Utilizing a patented hydrostatically balanced piston structure, internal friction is minimized, delivering up to 95% of theoretical torque even at startup.

• Elite Low-Speed Control: Ensures ultra-smooth operation at speeds below 1 RPM, effectively eliminating any “stick-slip” effects for precision maneuverability.

• High-Pressure Resilience: Rated for continuous operation at 250 Bar with extreme shock load resistance, ensuring an extended service life in harsh environments.

• Modular Configuration Options: Available with various shaft ends (keyed, splined), mounting flanges, and integrated control valve blocks tailored to diverse industrial needs.

• Target Applications: Marine crane hoists, offshore positioning winches, industrial mixers, and tunnel boring machine (TBM) drives.
