Power Range: Our marine motors cover a wide spectrum from tens to thousands of kilowatts, offering proven models that provide flexible solutions for main propulsion and auxiliary power needs across all vessel types, from small fishing boats to large engineering ships.
Rated Voltage: The product line supports multiple common voltage levels, including 380V, 440V, 690V, and higher specifications, ensuring compatibility with mainstream domestic and international shipboard grid standards for easier system integration and power matching.
Efficiency Class: The entire series meets or exceeds the IE3 premium efficiency standard, with select models achieving the IE4 super-premium class. Efficiency is particularly optimized for the common load range, ensuring significant energy savings during actual operation.
Power Factor: Utilizing scientific electromagnetic design and material application, our motors deliver a high power factor at rated load. This reduces reactive power loss, lessens the burden on the ship’s electrical network, and enhances the overall efficiency of the power system.
Protection Class: Featuring a standard IP56 rating for effective protection against wave spray and dust ingress. Higher protection levels (e.g., IP66) are available upon request to ensure safe and reliable operation in exposed deck areas or damp compartment environments.
Frame Material: Constructed with high-strength cast iron or cast aluminum alloy frames, combining structural robustness with light weight. Surfaces receive specialized anti-corrosion and salt-spray treatments, offering exceptional weather resistance to withstand harsh marine environments.
Cooling Method: Primarily employs totally enclosed fan-cooled (IC411) or water-jacket cooled (ICW81A) designs. These provide high cooling efficiency, ensuring reliable long-term operation and controlled temperature rise in enclosed spaces or high ambient temperatures.
Insulation Class: Stator windings utilize Class F or Class H insulation systems, processed with Vacuum Pressure Impregnation (VPI). The insulation materials offer high temperature, moisture, and vibration resistance, providing substantial electrical safety margins and significantly extended service life.
Mounting Type: Available in various standard configurations including B3 (foot-mounted), B5 (flange-mounted), and B35 (foot and flange-mounted). Designs are compact with precise installation dimensions, ensuring compatibility with diverse shipboard foundations and connection requirements.
Bearing Type: Equipped with heavy-duty deep groove ball bearings or cylindrical roller bearings, paired with long-life grease lubrication and high-quality sealing. These bearings offer high load capacity, extended lubrication intervals, and are specifically suited for vessel pitch and roll conditions.
Starting Torque: High starting torque, typically exceeding 150% of rated torque. Ensures smooth, reliable, and responsive starts under heavy-load conditions or during sudden propeller load changes.
Breakdown Torque: Superior breakdown torque ratio, generally over 200% of rated torque. Provides ample overload capacity to handle short-term peak demands in rough sea conditions, preventing unexpected stalling.
Noise Level: Designed for quiet operation with noise levels below 85 dB(A) at rated load (specific values vary by power). Optimized airflow and electromagnetic design minimize aerodynamic and electromagnetic noise for enhanced onboard comfort.
Vibration Level: High-precision dynamic balancing of the rotor ensures overall vibration meets the “Good” class according to ISO 10816 standards. Smooth operation with minimal mechanical vibration protects both the motor and connected equipment.
Duty Cycle: Designed for S1 continuous duty, with robust construction and cooling margins to reliably handle intermittent and variable shipboard operating cycles (S2-S10), supporting both long-term continuous and periodic marine missions.
Operating Temperature: Designed for ambient temperatures from -25°C to +50°C. Insulation and lubrication systems are optimized for high-temperature environments, ensuring stable performance without degradation in tropical waters or hot engine rooms.
Altitude: Standard models are suitable for altitudes up to 1000 meters. For higher altitude applications, special design and derating are available to ensure sufficient insulation and cooling capacity, accommodating global shipping routes.
Safety Certifications: Products hold full CCS (China Classification Society) type approval. Certifications from other major international classification societies such as ABS, DNV, and BV are available upon request, ensuring compliance with global maritime safety and environmental regulations.
Warranty Period: We provide an 18-month warranty from the date of delivery. The warranty covers defects in materials and workmanship, underscoring our confidence in product reliability.
Compliance Standards: Design and manufacturing strictly adhere to international electrical standards including IEC 60034 and ISO 8528, as well as the electrical equipment rules of major classification societies. This guarantees industry-leading performance, safety, and environmental adaptability.
