I. Four Core Advantages for Extreme Marine Environments
Corrosion Resistance: stainless steel shell + special ceramic coating, no rust after salt spray test, complying with NORSOK M-001 standard;
Wide-Range Adaptability: Stable operation at -40℃~85℃, IP68 protection to isolate seawater, and resistance to typhoon-level strong winds of 60m/s;
High Efficiency & Precision: Permanent magnet synchronization technology achieves over 96% energy efficiency, saving 20%~30% energy, with a speed control accuracy of ±1rpm;
Long-Term Reliability: 15-year design life, and maintenance-free structure to reduce operation and maintenance costs.
II. Scenario-Specific Adaptation to Empower Core Operating Equipment
(1) Marine Cranes: Stable Heavy Load Control for Multi-Posture Operations
The motors feature 1.5x instantaneous overload capacity, and the field-weakening speed regulation technology meets the switching demand of “high speed under light load and low speed under heavy load”:
Fixed Boom Crane: permanent magnet motor, stable operation at 0-1500rpm;
Knuckle Boom Crane: high-torque motor, optimizing the coordination of multi-joint linkage;
Lattice Boom Crane: dual-motor redundancy design to ensure heavy load safety, with 10ms emergency braking response.
(2) Marine Winches: Constant Force Traction to Resist Dynamic Loads
The torque closed-loop control achieves ±2% tension accuracy, and the low-speed and high-torque characteristics are suitable for deep-water operations:
Mooring/Pipe-Laying Winches: Constant tension output to avoid steel cable breakage, adapting to load fluctuations caused by ocean waves;
Deep-Water Anchoring Winches: Stable torque in the low-speed range of 5-100rpm, enabling precise control of anchor chain lowering.
