Kawasaki Staffa HMB, HMC & HMK High Torque Five Star Radial Motors

Product Overview: The Kawasaki Staffa Series is the definitive global standard for Low Speed High Torque (LSHT) hydraulic transmission. Famously known as “Five Star Motors” for their distinct radial piston layout, this range features the HMB (Fixed), HMC (Dual Displacement), and the heavy-duty HMK (Enhanced) series. This selection covers the entire spectrum: from the compact HMB030/P/F/21 to mid-range HMC045 and HMB200, up to the high-capacity HMB325 and HMB400. Notably, it includes the HMK Enhanced Series (e.g., HMKC200T3, HMKB100T3), engineered for higher pressures and extreme shock loads. These motors are the premier choice for marine winches, injection molding drives, offshore platforms, port machinery, and heavy shredders.

Key Technical Advantages:

• Superior Starting Torque: Hydrostatically balanced piston designs ensure massive torque output even at zero RPM, facilitating smooth starts for heavy machinery under full load.

• Dynamic Dual-Displacement (HMC/HMKC Series): Models like HMC045 and HMKC200 allow on-the-fly displacement shifts, enabling a seamless transition between high torque and high speed.

• HMK Reinforced Architecture: HMKB100 and HMKC200 utilize advanced valve plate technology and reinforced bearings, offering higher pressure ratings and superior fatigue resistance for high-cycle operations.

• Peak Pressure Resilience: Standard series rated at 250 Bar, while the HMK series manages higher transient peaks, maintaining stability under severe overloads.

• Extreme Mechanical Efficiency: The classic radial configuration minimizes internal friction, ensuring consistent torque output across the entire speed range.

• Target Applications: Heavy-duty winch propulsion, deck machinery, scrap shearers, TBMs, high-capacity injection molding, and mining conveyors.
